What Is Social Freez­ing for Men (Sperm Cry­op­reser­va­tion)?

You may not want chil­dren today, but can well imag­ine start­ing a fam­i­ly at a lat­er time. Before a planned vasec­to­my or a med­ical treat­ment that could impair fer­til­i­ty, the desire may also arise to pre­serve sperm as a pre­cau­tion. As you age, the ques­tion of how your own sperm qual­i­ty is devel­op­ing and whether ear­ly pre­cau­tion­ary mea­sures make sense can also become more impor­tant.

In social freez­ing for men, sperm are frozen as a pre­cau­tion and stored for pos­si­ble lat­er use. In so-called sperm cry­op­reser­va­tion, a semen sam­ple is exam­ined, pre­pared, and deep-frozen at approx­i­mate­ly −196 °C. This allows sperm to be stored long-term and used when need­ed as part of a lat­er fer­til­i­ty treat­ment. If freez­ing is done with­out an acute med­ical rea­son, it is referred to as social freez­ing.

The goal is to pre­serve the pos­si­bil­i­ty of lat­er fam­i­ly plan­ning. Whether and when freez­ing sperm may make sense for you per­son­al­ly depends on your indi­vid­ual sit­u­a­tion and should be dis­cussed with a physi­cian.

Lat­er Use of Frozen Sperm

  • Insem­i­na­tion (IUI): Here, the sperm are placed into the part­ner’s uterus at the appro­pri­ate time.
  • IVF: In this pro­ce­dure, an egg is arti­fi­cial­ly fer­til­ized.
  • ICSI: In ICSI, we specif­i­cal­ly inject one sperm into an egg.

Which treat­ment is most suit­able in an indi­vid­ual case depends on var­i­ous factors—particularly the qual­i­ty and num­ber of frozen sperm, but also the age and med­ical con­di­tions of the part­ner. If lat­er insem­i­na­tion is to be an option, it may make sense to freeze a larg­er num­ber of semen sam­ples today, as a cor­re­spond­ing sam­ple is required for each treat­ment attempt. With IVF or ICSI treat­ment, however—depending on sperm quality—fewer frozen sam­ples may be suf­fi­cient. We there­fore take into account which options you wish to keep open for lat­er when plan­ning cry­op­reser­va­tion.

When Does Freez­ing Sperm Make Sense?

Logo Ikon For Future Fam­i­ly Plan­ning

Fam­i­ly plan­ning does not always fit the cur­rent moment in life. Per­haps you want to focus first on edu­ca­tion or career, the right part­ner for start­ing a fam­i­ly is not yet there, or you sim­ply want to take your time with the top­ic of chil­dren and fam­i­ly. If you can gen­er­al­ly imag­ine becom­ing a father lat­er, you can freeze sperm today and thus pre­serve sperm from your cur­rent life phase for the future. In so-called social freez­ing for men, sperm are frozen as a pre­cau­tion and stored for pos­si­ble lat­er fer­til­i­ty treat­ment. This does not com­mit you to any­thing today. Rather, you pre­serve an addi­tion­al option for the future—for the time when a fam­i­ly fits into your life.

Logo Ikon With Increas­ing Age

Male fer­til­i­ty also changes with age—though more slow­ly and lat­er than in women. There is no fixed age lim­it for men. How­ev­er, as you age, the num­ber, motil­i­ty, and qual­i­ty of sperm can change. DNA changes in sperm also occur more fre­quent­ly. Stud­ies also show asso­ci­a­tions between high­er pater­nal age and an increased risk of mis­car­riage as well as cer­tain genet­ic and neu­rode­vel­op­men­tal dis­or­ders in the child. A real­is­tic per­spec­tive is impor­tant to us here: the absolute risks remain low over­all, and men of advanced age can of course have healthy chil­dren. If you con­scious­ly wish to post­pone your desire for chil­dren to a lat­er time, it may there­fore make sense to con­sid­er freez­ing sperm ear­ly. With a semen analy­sis, we can assess your cur­rent sperm qual­i­ty and dis­cuss togeth­er whether cry­op­reser­va­tion makes sense for you per­son­al­ly.

Logo Ikon Before Med­ical or Drug Treat­ment

Before med­ical pro­ce­dures such as surg­eries, chemother­a­py, or radi­a­tion ther­a­py, as well as before a planned vasec­to­my, fer­til­i­ty can be per­ma­nent­ly impaired. Cry­op­reser­va­tion offers the oppor­tu­ni­ty to pre­serve sperm cells as a pre­cau­tion and keep the option of lat­er father­hood open.

Logo Ikon Freeze Sperm Before Vasec­to­my

Any­one who decides on a vasec­to­my gen­er­al­ly con­sid­ers their fam­i­ly plan­ning com­plete. How­ev­er, life sit­u­a­tions and per­son­al wish­es can change. If you wish to pre­serve an addi­tion­al option for this even­tu­al­i­ty, you can freeze sperm before the vasec­to­my and have them stored long-term. The frozen sperm are avail­able to you for fer­til­i­ty treat­ment if you lat­er wish to have chil­dren. We will dis­cuss indi­vid­u­al­ly with you how many semen sam­ples make sense for this pur­pose.

Logo Ikon Freeze Sperm Before Gen­der-Affirm­ing Treat­ment

Before gen­der-affirm­ing hor­mone ther­a­py or cer­tain sur­gi­cal pro­ce­dures, it may make sense to think about your own fam­i­ly plan­ning. In par­tic­u­lar, longer-term hor­mone ther­a­py can sig­nif­i­cant­ly reduce or halt sperm pro­duc­tion. If you wish to keep open the pos­si­bil­i­ty of hav­ing a child lat­er with your own sperm, you can freeze them before start­ing treat­ment and have them stored long-term. We are hap­py to advise you per­son­al­ly on the appro­pri­ate tim­ing and the process of cry­op­reser­va­tion.

Freez­ing Sperm: Assess­ment by Our Experts

Gold stan­dard

The goal of cry­op­reser­va­tion is to pre­serve sperm in the best pos­si­ble qual­i­ty for a lat­er time. Mod­ern cry­op­reser­va­tion meth­ods have been estab­lished for many years and are an inte­gral part of mod­ern fer­til­i­ty treat­ments. They are designed to freeze sperm as gen­tly as pos­si­ble and store them long-term. Freez­ing sperm is par­tic­u­lar­ly advis­able before med­ical pro­ce­dures that can impair fer­til­i­ty or when fam­i­ly plan­ning is intend­ed for lat­er.

For lat­er fer­til­i­ty treat­ment, it is not crit­i­cal that every sin­gle sperm sur­vives the process unchanged. After thaw­ing, the sam­ple is pre­pared in the lab­o­ra­to­ry, and sperm that are as motile and suit­able as pos­si­ble are select­ed for treat­ment. We there­fore assess the sperm before freez­ing with a semen analy­sis to esti­mate the ini­tial qual­i­ty and indi­vid­u­al­ly rec­om­mend how many sam­ples should be stored for mean­ing­ful pre­cau­tion­ary mea­sures.

Sup­ple­men­tary treat­ments & addi­tion­al options

Semen analy­sis

The semen analy­sis is the basic exam­i­na­tion for assess­ing male fer­til­i­ty. Among oth­er things, sperm count, motil­i­ty, and mor­phol­o­gy are ana­lyzed. The results pro­vide infor­ma­tion on whether and in what form freez­ing sperm makes sense.

DNA Frag­men­ta­tion

The DNA frag­men­ta­tion test eval­u­ates the genet­ic integri­ty of sperm. Increased frag­men­ta­tion can affect fer­til­iza­tion capac­i­ty. The test pro­vides addi­tion­al infor­ma­tion, espe­cial­ly in cas­es of reduced sperm qual­i­ty or unful­filled desire for chil­dren.

Hor­mon­al Assess­ment

A hor­mon­al exam­i­na­tion can be use­ful to assess the hor­mon­al pre­req­ui­sites for fer­til­i­ty. It helps to bet­ter clas­si­fy pos­si­ble caus­es of reduced sperm qual­i­ty and coor­di­nate fur­ther pro­ce­dures.

TESE (Tes­tic­u­lar Sperm Extrac­tion)

If no sperm or only severe­ly lim­it­ed sperm are found in the ejac­u­late, tis­sue can be removed from the testis dur­ing a small biop­sy (TESE). This tis­sue can either be frozen for lat­er use or the sperm can be used direct­ly as part of assist­ed repro­duc­tion.

Process: How Freez­ing Sperm Works

The process of freez­ing sperm is clear­ly struc­tured and takes place in sev­er­al coor­di­nat­ed steps. The goal is to safe­ly obtain the sperm, assess them med­ical­ly, and pre­serve them long-term.

  1.  Con­sul­ta­tion Appoint­ment and Semen Analy­sis

    At the begin­ning, we dis­cuss your per­son­al sit­u­a­tion, your med­ical his­to­ry, and the rea­son why you wish to freeze sperm.

    We explain the process of cry­op­reser­va­tion and dis­cuss what pos­si­bil­i­ties it offers for your lat­er fam­i­ly plan­ning and where its lim­its lie. The con­sul­ta­tion appoint­ment can take place on-site, by tele­phone, or via video con­sul­ta­tion. After­wards, a semen analy­sis can be per­formed to assess the num­ber, motil­i­ty, and oth­er impor­tant char­ac­ter­is­tics of the sperm. You are also wel­come to have the semen analy­sis done before the con­sul­ta­tion appoint­ment. We can then dis­cuss the find­ings togeth­er direct­ly and assess how many semen sam­ples may make sense in your per­son­al sit­u­a­tion.

    Make an appoint­ment
  2. Pro­vide Semen Sam­ple

    You can pro­vide the semen sam­ple in a pri­vate, qui­et room at our cen­ter. If you live no more than about 30 to 40 min­utes from our prac­tice, you can also col­lect the sam­ple at home and then bring it to us.

    We will of course explain in advance what you should pay atten­tion to dur­ing col­lec­tion and trans­port. Before freez­ing, we also require a blood test for cer­tain infec­tious dis­eases, par­tic­u­lar­ly HIV as well as hepati­tis B and C. This test is legal­ly required for cry­op­reser­va­tion of sperm and can be per­formed direct­ly at our cen­ter. Depend­ing on sperm qual­i­ty and your per­son­al plan­ning, it may make sense to freeze sev­er­al semen sam­ples. We will dis­cuss indi­vid­u­al­ly with you how many col­lec­tions we rec­om­mend in your case.

  3. Pre­pare and Freeze Sperm (Cry­op­reser­va­tion)

    After col­lec­tion, the semen sam­ple is care­ful­ly exam­ined direct­ly in our lab­o­ra­to­ry and pre­pared for cry­op­reser­va­tion.

    Among oth­er things, we assess the num­ber and motil­i­ty of the sperm. We then pre­pare the sam­ple in a spe­cial cry­opro­tec­tive medi­um, freeze it in a con­trolled man­ner, and store it at approx­i­mate­ly −196 °C in liq­uid nitro­gen (cry­op­reser­va­tion).

  4. Store Sperm Long-Term

    After cry­op­reser­va­tion, your semen sam­ples are clear­ly labeled, doc­u­ment­ed, and stored for you in our mod­ern cryos­tor­age facil­i­ty.

    There they remain avail­able to you for lat­er fer­til­i­ty treat­ment even after many years. Estab­lished safe­ty and qual­i­ty stan­dards apply to stor­age. The sam­ples are care­ful­ly assigned and the con­di­tions in the cryos­tor­age facil­i­ty are con­tin­u­ous­ly mon­i­tored. You decide your­self how long you wish to store your sperm. We will of course inform you in advance about stor­age, costs, and all orga­ni­za­tion­al mat­ters.

Freeze Sperm at Our Cen­ter in Munich

Freez­ing sperm is a very per­son­al deci­sion. It is there­fore impor­tant to us that you feel well advised and that the entire process is sim­ple, dis­creet, and uncom­pli­cat­ed for you.

Sched­ule Con­sul­ta­tion Appoint­ment
  • Per­son­al Con­sul­ta­tion

    We will review your indi­vid­ual sit­u­a­tion and your semen analy­sis and dis­cuss with you whether cry­op­reser­va­tion makes sense, how many sam­ples we rec­om­mend, and what options you can keep open for lat­er.

  • Every­thing under one roof

    Con­sul­ta­tion, semen analy­sis, lab­o­ra­to­ry, cry­op­reser­va­tion, and long-term stor­age all take place direct­ly at our cen­ter in Munich. You have short dis­tances and ded­i­cat­ed con­tacts, and your sam­ple does not need to be trans­port­ed between dif­fer­ent facil­i­ties for the indi­vid­ual steps.

  • Dis­creet Sam­ple Col­lec­tion

    For col­lect­ing the semen sam­ple, a pri­vate, pro­tect­ed room is avail­able to you at our cen­ter. If you live near­by and can bring the sam­ple to us with­in the required time win­dow, sam­ple col­lec­tion at home is also pos­si­ble after pri­or arrange­ment.

  • Own lab­o­ra­to­ry

    Your semen sam­ple is exam­ined, pre­pared, and cry­op­re­served direct­ly in our own lab­o­ra­to­ry. Your sam­ple thus remains entire­ly with­in our cen­ter from exam­i­na­tion to long-term stor­age.

  • On-Site Cryos­tor­age

    The sperm are then stored at −196 °C in liq­uid nitro­gen in our on-site cryos­tor­age facil­i­ty. If you wish to use your frozen sperm lat­er for fer­til­i­ty treat­ment, this can be per­formed direct­ly at our cen­ter if desired. The sam­ples are avail­able on-site and do not need to be sent to anoth­er cen­ter first.

After visiting two other fertility clinics (one of which I left in tears), I had almost lost hope of finding a place where I would truly feel heard. Then I met Dr. Sarah Comploj, and everything changed. From the very first consultation, I felt genuinely listened to and treated as an individual. Unlike my previous experiences, where I was quickly told I needed IVF without anyone really taking the time to understand my situation or carefully review my test results, here I felt that my case truly mattered. Every step was explained thoughtfully, and my concerns were taken seriously. What stood out the most was that I never felt like just another patient or that the focus was on money. Instead, I felt that the entire team was committed to helping me achieve my dream in the most appropriate and personal way possible. Today, I am holding my one-month-old baby in my arms, and I will forever be grateful for the care, compassion, and expertise I received here. I can only highly recommend this clinic and Dr. Comploj 🩷

Every appointment I’ve had over the last few months has been consistently informative, professional, and conducted in a personal manner. The treatment plan was explained in detail and any concerns or questions always answered. She also speaks perfect English if required. I’m impressed with how well organised the clinic is and how quickly results are processed, and last-minute appointments made available. For anyone who is going through the struggle of infertility it’s a difficult and vulnerable time, but I always felt so reassured and in good hands with Dr Mann.

Our multiple years-long Kinderwunsch journey was spent under the care of Dr. Mann and her Kinderwunsch practice team. Dr. Mann is not only a highly competent expert in her field, she's also empathetic and kind. She treated each appointment with a sense of being genuinely invested — listening to concerns or questions, planning for my unique treatment needs, and explaining processes or procedures without rushing (because she knows it's likely your first time going through something ... even though it might be her 40000th time). Her practice is busy and it's because she's the best. The practice team is cheerful and helpful. The waiting area is comfortable with pleasant music, flowers, and they even laid out gingerbread during Christmas time. They have a lab on-site so results are often same-day. I particularly found the technology they use to share results via email quickly so helpful. And I always felt at ease speaking in my native language and not pressured to try to keep up with unfamiliar German terminology. I'm forever grateful to have found Dr. Mann. We plan to visit soon with our new plus-one :) - RB & JB

We had an absolutely wonderful experience with Dr. Mann. Her positive energy and competence was so reassuring and much appreciated during the potentially stressful time of trying to have a baby. I really loved how we could communicate in either English or German over complicated and sensitive reproductive matters. She took the time to answer all of our questions and offered us a wealth of information regarding the treatments. And her staff brought the same good vibes and Expertise to the practice. Some of the best and painless blood draws I’ve ever had, and they were always very responsive through emails as well as telephone communication. Online appointment system was also great. Video consults super convenient. The setting of the practice itself is an oasis of peace and calmness. As soon as I stepped through the doors I felt relaxed with the music, green plant wall, and well designed and decorated space. Technology and quality of equipment is very good. Yes, sometimes the waiting time had been 30+ minutes, but because the patient care is so excellent, I’ll be back for future treatments as needed, and would highly recommend this practice and team to anyone.

Costs for Freez­ing Sperm in Munich

The costs for freez­ing sperm con­sist of prepara­to­ry diag­nos­tics, cry­op­reser­va­tion, and sub­se­quent stor­age. Before freez­ing, we first exam­ine the num­ber, motil­i­ty, and qual­i­ty of your sperm with a semen analy­sis. This allows us to assess whether and how many semen sam­ples should be frozen for mean­ing­ful pre­cau­tion­ary mea­sures.

In addi­tion, an infec­tion screen­ing for HIV as well as hepati­tis B and C is required before cry­op­reser­va­tion.

To the cost overview
Semen Analy­sis — approx. €165

The semen analy­sis is used to exam­ine semen qual­i­ty and pro­vides infor­ma­tion on the num­ber, motil­i­ty, and mor­phol­o­gy of sperm. An extend­ed semen analy­sis includ­ing DNA frag­men­ta­tion analy­sis is avail­able for approx­i­mate­ly €395.

A DNA frag­men­ta­tion analy­sis is not required for every man. We will dis­cuss indi­vid­u­al­ly with you whether fur­ther exam­i­na­tion makes sense in your sit­u­a­tion.

Make an appoint­ment
Infec­tion Screen­ing — approx. €80

The infec­tion screen­ing includes the required tests for HIV as well as hepati­tis B and C and serves as safe prepa­ra­tion for cry­op­reser­va­tion.

Make an appoint­ment
First Semen Sam­ple — approx. €590

The first semen sam­ple is pre­pared in our own lab­o­ra­to­ry, frozen, and then safe­ly stored in our cryos­tor­age facil­i­ty at −196 °C.

Make an appoint­ment
Long-Term Stor­age — approx. €380/year

Your cry­op­re­served sperm are stored long-term at −196 °C in our on-site cryos­tor­age facil­i­ty. For lat­er fer­til­i­ty treat­ment, the sam­ples are avail­able direct­ly at our cen­ter.

Notes on Billing

No fixed or flat-rate prices: We bill on the basis of the offi­cial scale of fees for doc­tors (GOÄ). Accord­ing to the GOÄ, we are not allowed to quote fixed or flat-rate prices for med­ical ser­vices. The prices men­tioned are intend­ed to pro­vide ori­en­ta­tion and are typ­i­cal for the treat­ments men­tioned.

Pos­si­ble VAT Lia­bil­i­ty: Med­ical ser­vices may be sub­ject to VAT (cur­rent­ly 19%). This applies if, after diag­nos­tics, no med­ical indi­ca­tion or con­firmed diag­no­sis is present and it is there­fore not a med­ical treat­ment in the strict sense. This may par­tic­u­lar­ly be the case for social freez­ing treat­ments, but also for treat­ment of sin­gle moth­ers and same-sex cou­ples.

Note on Cost Cov­er­age by Health Insur­ance

If you wish to freeze your sperm as a pre­cau­tion for your lat­er fam­i­ly planning—for exam­ple, before a vasec­to­my or because your desire for chil­dren is planned for a lat­er stage of life—this is gen­er­al­ly a self-pay ser­vice. You then bear the costs for diag­nos­tics, cry­op­reser­va­tion, and long-term stor­age your­self.

With pri­vate health insur­ance, cost cov­er­age may be pos­si­ble, par­tic­u­lar­ly in cas­es of med­ical indi­ca­tion. How­ev­er, whether and to what extent costs are cov­ered depends on your indi­vid­ual insur­ance con­tract and plan. We there­fore rec­om­mend clar­i­fy­ing cost cov­er­age with your pri­vate health insur­ance before begin­ning cry­op­reser­va­tion. We are hap­py to pro­vide you with a cor­re­spond­ing cost esti­mate for this pur­pose.

For those with statu­to­ry health insur­ance, there is a right to cost cov­er­age under cer­tain con­di­tions if a germ cell-dam­ag­ing treat­ment is immi­nent due to an ill­ness and freez­ing the sperm is med­ical­ly necessary—for exam­ple, before chemother­a­py, radi­a­tion, or oth­er fer­til­i­ty-dam­ag­ing treat­ments. This cost cov­er­age is pro­vid­ed with­in the frame­work of statu­to­ry med­ical care. Since we are a pri­vate fer­til­i­ty cen­ter, we can­not bill this ser­vice through statu­to­ry health insur­ance.

It may also be worth look­ing at your employ­er’s ben­e­fits: some com­pa­nies now con­tribute to the costs of fer­til­i­ty preser­va­tion and social freez­ing as part of their employ­ee ben­e­fits. Whether freez­ing and stor­ing sperm are includ­ed depends on the respec­tive ben­e­fit pro­gram.

Fre­quent­ly Asked Ques­tions About Freez­ing Sperm

Can You Freeze Semen?

Yes. After appro­pri­ate prepa­ra­tion, sperm can be cry­op­re­served at approx­i­mate­ly −196 °C in liq­uid nitro­gen and stored long-term. This can make sense both for per­son­al rea­sons and before cer­tain med­ical treat­ments.

How Does Freez­ing Sperm Work Specif­i­cal­ly?

First, we dis­cuss your per­son­al sit­u­a­tion and exam­ine semen qual­i­ty with a semen analy­sis. After the required infec­tion screen­ing, you pro­vide a semen sam­ple. This is exam­ined and pre­pared in our lab­o­ra­to­ry, mixed with a cry­opro­tec­tive medi­um, and then cry­op­re­served at approx­i­mate­ly −196 °C in liq­uid nitro­gen. The sam­ple can then be stored long-term in our cryos­tor­age facil­i­ty.

Up to What Age Can You Freeze Sperm?

A gen­er­al med­ical age lim­it for pre­cau­tion­ary freez­ing of sperm can­not be mean­ing­ful­ly estab­lished. What mat­ters are your cur­rent sperm qual­i­ty, your health sit­u­a­tion, and your fam­i­ly plan­ning. With a semen analy­sis, we can assess your per­son­al start­ing sit­u­a­tion.

How Long Can You Freeze Sperm?

Sperm can be stored at approx­i­mate­ly −196 °C in liq­uid nitro­gen for very long peri­ods. At these tem­per­a­tures, the bio­log­i­cal process­es of the cells prac­ti­cal­ly come to a stand­still. The sperm there­fore do not age bio­log­i­cal­ly fur­ther dur­ing cryos­tor­age.

Accord­ing to cur­rent sci­en­tif­ic knowl­edge, there is no known bio­log­i­cal max­i­mum dura­tion after which sperm could no longer be used sole­ly due to stor­age time. For the qual­i­ty of stored sperm, the ini­tial qual­i­ty of the semen sam­ple and the tim­ing of freez­ing are there­fore decisive—not the dura­tion of sub­se­quent stor­age.

How Many Semen Sam­ples Should I Freeze?

How many semen sam­ples make sense can­not be deter­mined across the board. Deci­sive fac­tors include your cur­rent sperm qual­i­ty, the rea­son for cry­op­reser­va­tion, and your per­son­al fam­i­ly plan­ning. The ques­tion of whether you wish to have one or more chil­dren lat­er and for which fer­til­i­ty treat­ment the sperm may be used also plays a role.

After the first semen analy­sis, we can assess the ini­tial sit­u­a­tion and plan togeth­er with you how many sam­ples make sense and how many col­lec­tions are need­ed for this. For lat­er insem­i­na­tion, for exam­ple, more sperm are usu­al­ly need­ed than for ICSI. Depend­ing on sperm qual­i­ty, a small­er num­ber may already be suf­fi­cient; in oth­er sit­u­a­tions, we rec­om­mend freez­ing a larg­er num­ber of semen sam­ples.

How Long Must I Abstain Before Semen Col­lec­tion?

We gen­er­al­ly rec­om­mend an absti­nence peri­od of a few days before semen col­lec­tion. How­ev­er, the opti­mal dura­tion may depend on your sperm qual­i­ty and the planned exam­i­na­tion. We will inform you before the appoint­ment what absti­nence peri­od makes sense in your per­son­al sit­u­a­tion.

Can I Col­lect the Semen Sam­ple at Home?

Yes, if you live near our prac­tice, this is pos­si­ble after pri­or arrange­ment. The sam­ple must be brought to us with­in the agreed time win­dow and under suit­able con­di­tions.

What Does the Qual­i­ty of Frozen Sperm Depend On?

The qual­i­ty of the semen sam­ple at the time of freez­ing is deci­sive. The num­ber, motil­i­ty, and vital­i­ty of the sperm play a par­tic­u­lar­ly impor­tant role. The freez­ing and thaw­ing process can also reduce the motil­i­ty of some of the sperm. We there­fore exam­ine the ini­tial sam­ple before cry­op­reser­va­tion with a semen analy­sis and can thus assess how many sam­ples may make sense for lat­er use.

How Can Frozen Sperm Be Used Lat­er?

After thaw­ing, the sperm are gen­er­al­ly used as part of fer­til­i­ty treat­ment. Depend­ing on num­ber and qual­i­ty, insem­i­na­tion, IVF, or ICSI may be options. Which method makes sense lat­er can only be assessed based on the con­di­tions that exist at that time.

Does Freez­ing Affect Sperm Qual­i­ty?

The goal of cry­op­reser­va­tion is to pre­serve sperm in the best pos­si­ble qual­i­ty for a lat­er time. Mod­ern cry­op­reser­va­tion meth­ods have been estab­lished for many years and are designed to freeze sperm as gen­tly as pos­si­ble and store them long-term. How­ev­er, the freez­ing and thaw­ing process is not entire­ly with­out effect: motil­i­ty and vital­i­ty in par­tic­u­lar may be low­er after thaw­ing. Sci­en­tif­ic stud­ies also show that changes to the cell mem­brane and an increase in DNA frag­men­ta­tion can occur in some of the sperm. How pro­nounced these changes are depends among oth­er things on the qual­i­ty of the ini­tial sam­ple and the freez­ing method used.

For lat­er fer­til­i­ty treat­ment, how­ev­er, it is not crit­i­cal that every sin­gle sperm sur­vives the process unchanged. After thaw­ing, the sam­ple is pre­pared in the lab­o­ra­to­ry and sperm that are as motile and suit­able as pos­si­ble are select­ed for treat­ment. Depend­ing on the num­ber and qual­i­ty of avail­able sperm, these can lat­er be used for insem­i­na­tion, IVF, or ICSI. We there­fore assess the sperm before freez­ing with a semen analy­sis. This allows us to esti­mate the ini­tial qual­i­ty and indi­vid­u­al­ly rec­om­mend how many sam­ples should be stored for mean­ing­ful pre­cau­tion­ary mea­sures.

What Does It Cost to Freeze Sperm?

The total costs con­sist of diag­nos­tics, cry­op­reser­va­tion, and long-term stor­age. You will find the cur­rent indi­vid­ual prices in our cost sec­tion above. If sev­er­al sam­ples make sense, we will pro­vide you with an indi­vid­ual cost overview in advance.

Does Health Insur­ance Cov­er Cry­op­reser­va­tion?

For social freez­ing, freez­ing sperm is gen­er­al­ly a self-pay ser­vice. In cas­es of med­ical indi­ca­tion, cost cov­er­age may be pos­si­ble. Since we are a pri­vate cen­ter, we can­not bill through statu­to­ry health insur­ance. Those with pri­vate insur­ance should clar­i­fy cost cov­er­age with their insur­er in advance.

Can I Freeze Sperm Before a Vasec­to­my?

If you wish to pre­serve an addi­tion­al option for a lat­er desire for chil­dren despite a planned vasec­to­my, cry­op­reser­va­tion before the pro­ce­dure may make sense. After a semen analy­sis, we can assess how many sam­ples are advis­able for this pur­pose.

What Hap­pens If No Sperm Are Found in the Semen Analy­sis?

If no sperm are detectable in the ejac­u­late, this does not nec­es­sar­i­ly mean that no sperm of your own can be obtained. Under cer­tain con­di­tions, sperm can be obtained direct­ly from tes­tic­u­lar tis­sue by means of TESE and sub­se­quent­ly cry­op­re­served.
