What is sperm dona­tion?

Sperm dona­tion is a form of fer­til­i­ty treat­ment in which donor sperm is used. It is used when the part­ner has no sperm or not enough func­tion­al sperm, or when women with­out a part­ner or les­bian cou­ples wish to have a child. Sperm dona­tion can be used as part of insem­i­na­tion (IUI) or IVF/ICSI treat­ment. The donor sperm comes from licensed sperm banks and is select­ed accord­ing to defined med­ical and genet­ic cri­te­ria.

  • Donor insem­i­na­tion

    If the con­di­tions for preg­nan­cy are good for the woman and at least one fal­lop­i­an tube is open, insem­i­na­tion with donor sperm can be a sim­ple and gen­tle option. The pre­pared donor sperm is placed direct­ly into the uterus at the appro­pri­ate time.

  • IVF/ICSI treat­ment

    If addi­tion­al fer­til­i­ty fac­tors play a role—for exam­ple blocked fal­lop­i­an tubes, endometrio­sis, a reduced ovar­i­an reserve, or old­er age—IVF or ICSI may be advis­able. The eggs are fer­til­ized with the donor sperm in the lab­o­ra­to­ry.

Who sperm dona­tion is suit­able for

Logo Ikon Cou­ples

If the part­ner has no sperm or only very lim­it­ed suit­able sperm, or if cer­tain genet­ic risks exist, treat­ment with donor sperm may be an option.

For les­bian cou­ples, sperm dona­tion is an estab­lished and legal­ly clear­ly reg­u­lat­ed way to enable pregnancy—either in the nat­ur­al cycle or in com­bi­na­tion with insem­i­na­tion or IVF/ICSI treat­ment.

Logo Ikon Sin­gle women

Women who wish to have a child with­out a part­ner can become preg­nant with the help of sperm dona­tion. Which treat­ment is appro­pri­ate depends on the per­son­al and med­ical sit­u­a­tion.

Spe­cial aspects of sperm dona­tion

Sperm dona­tion is med­ical­ly estab­lished and clear­ly reg­u­lat­ed by law. At the same time, it is a very per­son­al deci­sion that often rais­es ques­tions about genet­ic ori­gin and how to inform the child lat­er on.

  • Pro­fes­sion­al soci­eties rec­om­mend an open, age-appro­pri­ate approach to the child’s con­cep­tion sto­ry.
  • Chil­dren con­ceived through sperm dona­tion have a legal­ly reg­u­lat­ed right to infor­ma­tion about the iden­ti­ty of the sperm donor from the age of 16.
  • In med­ical­ly super­vised sperm dona­tion, the sperm donor does not become the child’s legal father and is not liable for child sup­port.
  • Ques­tions about genet­ic and social par­ent­hood can be dis­cussed calm­ly even before treat­ment begins.

We delib­er­ate­ly take plen­ty of time for your ques­tions and for the spe­cial med­ical, legal, and per­son­al aspects of treat­ment with sperm dona­tion. Our aim is not only to pro­vide you with excel­lent med­ical care, but also to give you space to dis­cuss your thoughts, wish­es, and any uncer­tain­ties in peace. We will dis­cuss the options for spe­cial­ized psy­choso­cial coun­sel­ing with you and sup­port you in find­ing a path that feels right and good for you.

Med­ical safe­ty & respon­si­ble sup­port

Treat­ment with donor sperm is an estab­lished method in repro­duc­tive med­i­cine and, for many dif­fer­ent fam­i­ly con­stel­la­tions, a way to achieve preg­nan­cy.

We work with care­ful­ly select­ed, licensed sperm banks in Ger­many and abroad, where donors are exam­ined accord­ing to defined med­ical, genet­ic, and qual­i­ty cri­te­ria.

Which treat­ment is appro­pri­ate for you depends on your per­son­al and med­ical sit­u­a­tion. Depend­ing on age, ovar­i­an reserve, cycle, fal­lop­i­an tube func­tion, and oth­er find­ings, insem­i­na­tion or IVF/ICSI may be con­sid­ered. Togeth­er, we choose the path that fits your cir­cum­stances and wish­es. How­ev­er, sperm dona­tion is about more than med­ical treat­ment alone. Ques­tions about select­ing a donor, genet­ic ori­gin, how to inform the child lat­er, and your own under­stand­ing of par­ent­hood can be very per­son­al. We delib­er­ate­ly take time for this and sup­port you with open­ness, appre­ci­a­tion, and with­out pres­sure. In addi­tion, we rec­om­mend spe­cial­ized psy­choso­cial coun­sel­ing for so-called gamete dona­tion.

Sup­port­ive coun­sel­ing & treat­ments

PSYCHOSOCIAL COUNSELING

Sperm dona­tion involves med­ical, legal, and emo­tion­al aspects alike. In accom­pa­ny­ing psy­choso­cial coun­sel­ing, top­ics dis­cussed with you include an open approach to the con­cep­tion sto­ry, social and bio­log­i­cal par­ent­hood, and pos­si­ble issues that may arise at dif­fer­ent stages of the child’s life. Indi­vid­ual questions—for exam­ple for solo moth­ers or same-sex couples—also have space here. This cre­ates clar­i­ty and strength­ens your deci­sion on a sta­ble foun­da­tion.

Cycle mon­i­tor­ing & mild stim­u­la­tion

Before insem­i­na­tion, the cycle can be mon­i­tored in a tar­get­ed way or gen­tly sup­port­ed hor­mon­al­ly to deter­mine the opti­mal time for treat­ment. Through indi­vid­ual adjust­ments, we increase the chance of suc­cess­ful treat­ment. Ther­a­py is always designed to be as gen­tle as pos­si­ble.

IVF/ICSI with donor sperm

If addi­tion­al fac­tors such as impaired fal­lop­i­an tube func­tion or reduced ovar­i­an reserve are present, IVF or ICSI with donor sperm may be med­ical­ly advis­able. Fer­til­iza­tion takes place in the lab­o­ra­to­ry under con­trolled con­di­tions. Espe­cial­ly in more com­plex start­ing sit­u­a­tions, this option offers a high­er like­li­hood of preg­nan­cy.

Cry­op­reser­va­tion of fer­til­ized eggs or embryos

If, as part of IVF or ICSI, more embryos devel­op than can be trans­ferred in that cycle, suit­able embryos can be frozen for lat­er treat­ments. This allows anoth­er embryo trans­fer at a lat­er time with­out the need for renewed stim­u­la­tion and egg retrieval.

Process of sperm dona­tion for fer­til­i­ty treat­ment

At our fer­til­i­ty cen­ter Die Kinder­wun­schärztin in Munich, we guide you in a struc­tured and empa­thet­ic way through all steps of treat­ment with sperm dona­tion. From med­ical prepa­ra­tion and select­ing a suit­able sperm bank through to per­form­ing insem­i­na­tion or IVF, each step fol­lows an indi­vid­u­al­ly coor­di­nat­ed treat­ment plan and is pro­vid­ed under per­son­al med­ical care.

  1. Ini­tial con­sul­ta­tion & med­ical plan­ning

    At the begin­ning, we take time to get to know your per­son­al sit­u­a­tion, your wish­es, and your pre­vi­ous expe­ri­ences in detail.

    We dis­cuss your med­ical his­to­ry, car­ry out the nec­es­sary exam­i­na­tions, and plan the next diag­nos­tic and med­ical steps togeth­er.

    Make an appoint­ment
  2. Legal and psy­choso­cial coun­sel­ing

    In addi­tion to med­ical aspects, sperm dona­tion also involves legal and per­son­al ques­tions.

    That is why we dis­cuss these top­ics with you ear­ly on and sup­port you in orga­niz­ing spe­cial­ized psy­choso­cial and—depending on your fam­i­ly constellation—legal coun­sel­ing. This allows impor­tant ques­tions to be clar­i­fied calm­ly before treat­ment begins.

  3. Select­ing the donor

    We then sup­port you in choos­ing a suit­able sperm bank and an appro­pri­ate donor.

    You will have access to ver­i­fied donor pro­files and can take your time to decide which donor is suit­able for you. If you have any ques­tions, we are always here for you.

  4. Plan­ning the treat­ment

    Once the med­ical pre­req­ui­sites have been clar­i­fied and you have select­ed a donor that is right for you, we plan the appro­pri­ate treat­ment togeth­er.

    Depend­ing on your sit­u­a­tion, this may be insem­i­na­tion in a nat­ur­al or sup­port­ed cycle, or IVF/ICSI treat­ment.

  5. Car­ry­ing out the treat­ment

    Treat­ment is car­ried out accord­ing to an indi­vid­u­al­ly coor­di­nat­ed plan. Dur­ing insem­i­na­tion, the pre­pared donor sperm is placed into the uterus at the appro­pri­ate time.

    Treat­ment is car­ried out accord­ing to an indi­vid­u­al­ly coor­di­nat­ed plan. Dur­ing insem­i­na­tion, the pre­pared donor sperm is placed into the uterus at the appro­pri­ate time. With IVF/ICSI, fer­til­iza­tion takes place in the lab­o­ra­to­ry, fol­lowed by embryo trans­fer.

  6. Preg­nan­cy test (approx. 14 days lat­er)

    About two weeks after insem­i­na­tion, or about 10 days after embryo trans­fer, the preg­nan­cy test is per­formed.

    We dis­cuss the result togeth­er and calm­ly plan the next steps with you.

We flew from overseas to work with Dr Mann and her team. Everyone was so kind, empathetic and extremely helpful. Everyone spoke English and made us feel very welcome. We could not have asked for better care than what we received from Dr Mann and her team. Bonus, the offices are beautiful.

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.

I had a wonderful experience with the Kinderwunsch practice, and especially with dr. Corina Mann. From the very beginning, dr Mann was attentive, knowledgeable, and truly invested in helping me achieve the best possible outcome. She took the time to understand my goals and tailored my treatment plan to make sure I had the best chance of success. Thanks to her care and expertise, I was able to maximise my results and reach my goals. I always felt supported, informed, and in the best hands. Dr Mann always answered my countless questions with a smile :) I’m incredibly grateful for her dedication and would wholeheartedly recommend her to anyone starting their fertility journey.

Since my doctor was busy and couldn't do the procedure herself, I had an appointment with Sarah to have my fallopian tubes checked. I was very nervous before the procedure, but it turned out to be for nothing! Sarah described and explained every step of the procedure and was extremely friendly.

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

Dr.Albrecht is really good and friendly. She is best at her own way. But reception staff is very very very worst and disappointing. They themselves book an appointment and say it’s not booked. Luckily in Doctorlib my appointment was visible. Staff is very very rude. And they respond very rudely. I can give 0 rating for Staff at reception.

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.

I have only the best words to describe my experience at the clinic. I personally worked with Dr. Albrecht and she was amazing. Every appointment was done on time, informative and clear on what the next steps are. She offered details and support with my every question. Where I wasn’t sure of my German we swapped to English to make sure I understood everything. The clinic is run in a very efficient way, organized, planned and as a process oriented person I loved it!

Costs of sperm dona­tion

The costs depend on which treat­ment is med­ical­ly appro­pri­ate for you. In addi­tion to med­ical con­sul­ta­tion and diag­nos­tics, there are costs for the donor sperm and its ship­ping, as well as for the fer­til­i­ty treat­ment itself. Depend­ing on the sit­u­a­tion, cycle mon­i­tor­ing, med­ica­tion, or addi­tion­al lab­o­ra­to­ry ser­vices may be added.

Before treat­ment begins, you will receive a trans­par­ent overview of the expect­ed costs.

To the cost overview
IUI with donor sperm — approx. €470–540

Insem­i­na­tion with donor sperm includ­ing med­ical and orga­ni­za­tion­al prepa­ra­tion as well as treat­ment per­for­mance.

The required appoint­ments for cycle mon­i­tor­ing and hor­mone checks are not includ­ed.

Make an appoint­ment
Cycle mon­i­tor­ing & hor­mone checks — approx. €180–200 per appoint­ment

Ultra­sound and hor­mone checks to deter­mine the opti­mal time for insem­i­na­tion. Usu­al­ly 1–3 appoint­ments are need­ed.

Make an appoint­ment
IVF with donor sperm - approx. €3,200–3,600

With IVF, the ovaries are stim­u­lat­ed, the eggs are retrieved, and then com­bined with the donor sperm in the lab­o­ra­to­ry. After suc­cess­ful fer­til­iza­tion, embryo trans­fer takes place.

The costs of IVF treat­ment include med­ical care, egg retrieval, fer­til­iza­tion in the lab­o­ra­to­ry, and embryo trans­fer. Fur­ther costs are incurred for the required med­ica­tion and anes­the­sia. Depend­ing on the indi­vid­ual sit­u­a­tion, addi­tion­al ser­vices such as cry­op­reser­va­tion may be added.

Make an appoint­ment
ICSI with donor sperm — approx. €6,200–6,900

With ICSI, a sin­gle sperm cell is inject­ed direct­ly into the egg. ICSI may be advis­able, for exam­ple, if a pre­vi­ous IVF treat­ment did not result in fer­til­iza­tion.

The treat­ment process is iden­ti­cal to IVF treat­ment. In the lab­o­ra­to­ry, how­ev­er, dur­ing intra­cy­to­plas­mic sperm injec­tion (ICSI), a sin­gle sperm cell is select­ed under the micro­scope and inject­ed direct­ly into the egg.

Make an appoint­ment
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 have been car­ried out, no med­ical indi­ca­tion or con­firmed diag­no­sis is present and it is there­fore not a med­ical treat­ment in the strict sense. This can be the case in par­tic­u­lar with social freez­ing treat­ments, but also with the treat­ment of sin­gle moms and same-sex cou­ples.

Note on Cost Cov­er­age

We would be hap­py to pro­vide you with detailed cost infor­ma­tion for the planned treat­ment in advance. This allows you to clar­i­fy cost cov­er­age with your pri­vate health insur­ance (PKV) as best as pos­si­ble before­hand. Statu­to­ry health insur­ance (GKV) does not cov­er costs at our cen­ter.

Fre­quent­ly asked ques­tions about sperm dona­tion

How does the selec­tion of a sperm donor work?

We work with licensed sperm banks in Ger­many and abroad and sup­port you with the selec­tion. You will receive access to ver­i­fied donor pro­files with infor­ma­tion, for exam­ple, on appear­ance, med­ical his­to­ry, and oth­er per­son­al char­ac­ter­is­tics. You can take your time to decide which donor is right for you.

Is sperm dona­tion anony­mous in Ger­many?

With med­ical­ly super­vised sperm dona­tion, the donor’s data is doc­u­ment­ed in the sperm donor reg­is­ter. This gives the child the oppor­tu­ni­ty lat­er to learn about their genet­ic ori­gin. Until the age of 16, the legal guardians can request infor­ma­tion; from the age of 16, the child can do so them­selves.
The sperm donor does not assume a legal parental role and is not liable for child sup­port.

What are the pre­req­ui­sites for insem­i­na­tion?

For insem­i­na­tion, at least one fal­lop­i­an tube should be open. We also take into account age, ovar­i­an reserve, the cycle, pos­si­ble pre-exist­ing con­di­tions, and oth­er med­ical fac­tors. If the chances of preg­nan­cy with insem­i­na­tion are low, IVF/ICSI may be more appro­pri­ate. We dis­cuss this with you depend­ing on your sit­u­a­tion.

How many attempts are typ­i­cal with sperm dona­tion?

This can­not be defined across the board. With insem­i­na­tion, sev­er­al cycles are often nec­es­sary because the chance of preg­nan­cy per attempt is lim­it­ed. Typ­i­cal­ly, sev­er­al insem­i­na­tion cycles are car­ried out first before the next steps are reassessed. With IVF/ICSI, the prob­a­bil­i­ty of suc­cess per cycle is gen­er­al­ly high­er, but it also involves greater med­ical effort. We dis­cuss the opti­mal treat­ment strat­e­gy with you indi­vid­u­al­ly.

Is psy­choso­cial coun­sel­ing manda­to­ry?

Psy­choso­cial coun­sel­ing is strong­ly rec­om­mend­ed by us and by pro­fes­sion­al soci­eties, but it is not manda­to­ry. Coun­sel­ing pro­vides space to calm­ly dis­cuss ques­tions about genet­ic ori­gin, how to inform the child lat­er, and your own under­stand­ing of par­ent­hood. We work with expe­ri­enced coun­sel­ing cen­ters and con­tacts and, if you wish, can con­nect you with the right per­son.

Do I also need legal coun­sel­ing?

Depend­ing on your fam­i­ly con­stel­la­tion, legal ques­tions can play an impor­tant role. We address these top­ics with you ear­ly on and, if need­ed, con­nect you with expe­ri­enced lawyers from our net­work.

How long does the entire process take from con­sul­ta­tion to treat­ment?

After the ini­tial con­sul­ta­tion, we first clar­i­fy the med­ical pre­req­ui­sites and plan the nec­es­sary exam­i­na­tions. In par­al­lel, the donor can be select­ed. Once all pre­req­ui­sites are met and the sperm sam­ple is avail­able, treat­ment can often begin with­in a few weeks or with one of the next cycles.

Some cou­ples also like to seek advice in advance and plan treat­ment for a lat­er time.

Is there an age lim­it for treat­ment with sperm dona­tion?

There is no gen­er­al legal age lim­it. How­ev­er, deci­sive fac­tors include age, ovar­i­an reserve, health pre­req­ui­sites, and the indi­vid­ual like­li­hood of preg­nan­cy. We dis­cuss these fac­tors with you open­ly and real­is­ti­cal­ly and plan treat­ment accord­ing­ly.

Is sperm dona­tion also pos­si­ble for sin­gle women?

Yes. We also treat women with­out a part­ner with donor sperm. We dis­cuss which med­ical and orga­ni­za­tion­al steps are nec­es­sary indi­vid­u­al­ly dur­ing the ini­tial con­sul­ta­tion.

Can les­bian cou­ples be treat­ed with donor sperm at our cen­ter?

Yes. We sup­port les­bian cou­ples in start­ing a fam­i­ly with donor sperm and plan treat­ment individually—depending on the med­ical sit­u­a­tion, as insem­i­na­tion or IVF/ICSI.

Can the same donor be used lat­er for a sib­ling?

Depend­ing on the sperm bank, it may be pos­si­ble to reserve addi­tion­al sam­ples from the same donor. If it is impor­tant to you to have a genet­ic sib­ling with the same donor, we rec­om­mend tak­ing this into account ear­ly when select­ing and reserv­ing.
