Com\u00admon caus\u00ades of an unful\u00adfilled wish to have a child<\/h2>\n\n\n\n

An unful\u00adfilled wish to have a child affects many cou\u00adples: Around one in six cou\u00adples do not become preg\u00adnant nat\u00adu\u00adral\u00adly with\u00adin a year. The caus\u00ades are varied\u2014and they may lie with the woman, the man, or both togeth\u00ader.
Sev\u00ader\u00adal fac\u00adtors often interact\u2014and some\u00adtimes the ini\u00adtial exam\u00adi\u00adna\u00adtions do not show any abnor\u00admal find\u00adings at first.
 
If preg\u00adnan\u00adcy does not occur over a longer peri\u00adod, it can there\u00adfore make sense to clar\u00adi\u00adfy pos\u00adsi\u00adble caus\u00ades in a tar\u00adget\u00aded way. It is not always nec\u00ades\u00adsary to wait for a spe\u00adcif\u00adic peri\u00adod first: In cas\u00ades of cycle dis\u00ador\u00adders, known pre-exist\u00ading con\u00addi\u00adtions, or oth\u00ader indi\u00adca\u00adtions of reduced fer\u00adtil\u00adi\u00adty, ear\u00adli\u00ader eval\u00adu\u00ada\u00adtion may also be advis\u00adable. <\/p>\n\n\n\n

For sound diag\u00adnos\u00adtics, it is cru\u00adcial to involve both part\u00adners equal\u00adly. Fer\u00adtil\u00adi\u00adty dis\u00ador\u00adders can have dif\u00adfer\u00adent causes\u2014hormonal, func\u00adtion\u00adal, struc\u00adtur\u00adal, or genet\u00adic. How\u00adev\u00ader, it is not always pos\u00adsi\u00adble to iden\u00adti\u00adfy a sin\u00adgle cause\u2014often a more com\u00adplete pic\u00adture only emerges from the inter\u00adac\u00adtion of var\u00adi\u00adous fac\u00adtors. <\/p>\n\n\n\n

Dis\u00ador\u00adders of the female hor\u00admon\u00adal bal\u00adance can mean that eggs do not mature, or only rarely mature, and ovu\u00adla\u00adtion does not occur. Signs may include irreg\u00adu\u00adlar, very long, or absent cycles.

Typ\u00adi\u00adcal fea\u00adtures are irreg\u00adu\u00adlar or absent ovu\u00adla\u00adtion and often ele\u00advat\u00aded andro\u00adgen lev\u00adels. Pos\u00adsi\u00adble accom\u00adpa\u00adny\u00ading symp\u00adtoms include acne, increased body hair, or hair loss; some women also have insulin resis\u00adtance.

Fer\u00adtil\u00adi\u00adsa\u00adtion takes place in the fal\u00adlop\u00adi\u00adan tube. If the fal\u00adlop\u00adi\u00adan tubes are blocked, dam\u00adaged, or impaired in their func\u00adtion by adhe\u00adsions, the egg and sperm can\u00adnot meet, or can only meet with dif\u00adfi\u00adcul\u00adty.

Age is a key influ\u00adenc\u00ading fac\u00adtor on female fer\u00adtil\u00adi\u00adty.

Infec\u00adtions and inflam\u00adma\u00adtion of the male gen\u00adi\u00adtal tract can impair sperm qual\u00adi\u00adty and, in some cas\u00ades, sperm trans\u00adport. These include inflam\u00adma\u00adtion of the tes\u00adti\u00adcles or epi\u00addidymis, for exam\u00adple after cer\u00adtain bac\u00adte\u00adr\u00adi\u00adal or sex\u00adu\u00adal\u00adly trans\u00admit\u00adted infec\u00adtions. Mumps orchi\u00adtis, espe\u00adcial\u00adly after puber\u00adty, can also per\u00adma\u00adnent\u00adly impair sperm pro\u00adduc\u00adtion. Depend\u00ading on the cause and sever\u00adi\u00adty, the changes may be tem\u00adpo\u00adrary or per\u00adma\u00adnent. <\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Even with nor\u00admal sperm pro\u00adduc\u00adtion, too few or no sperm may enter the ejac\u00adu\u00adlate if the sperm ducts are blocked or not ful\u00adly devel\u00adoped. Caus\u00ades can include pre\u00advi\u00adous inflam\u00adma\u00adtion, surgery, or injuries, as well as con\u00adgen\u00adi\u00adtal changes. In con\u00adgen\u00adi\u00adtal absence of the vas def\u00ader\u00adens, for exam\u00adple, changes in the CFTR gene may be the under\u00adly\u00ading cause. <\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Genet\u00adic changes are an impor\u00adtant cause of severe male fer\u00adtil\u00adi\u00adty dis\u00ador\u00adders. These include Kline\u00adfel\u00adter syn\u00addrome with an addi\u00adtion\u00adal X chro\u00admo\u00adsome as well as so-called AZF dele\u00adtions on the Y chro\u00admo\u00adsome. They can impair sperm pro\u00adduc\u00adtion to vary\u00ading degrees\u2014up to the com\u00adplete absence of sperm in the ejac\u00adu\u00adlate (azoosper\u00admia). In cas\u00ades of marked abnor\u00admal\u00adi\u00adties in the semen analy\u00adsis, genet\u00adic eval\u00adu\u00ada\u00adtion is there\u00adfore often advis\u00adable. <\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Hor\u00admon\u00adal dis\u00ador\u00adders can sig\u00adnif\u00adi\u00adcant\u00adly impair sperm pro\u00adduc\u00adtion. Sperm pro\u00adduc\u00adtion is reg\u00adu\u00adlat\u00aded by hor\u00admones from the brain, pitu\u00aditary gland, and tes\u00adti\u00adcles. Con\u00addi\u00adtions that dis\u00adrupt this reg\u00adu\u00adla\u00adtion can lead to reduced or absent sperm pro\u00adduc\u00adtion. Depend\u00ading on the find\u00adings, changes in FSH, LH, testos\u00adterone, or pro\u00adlactin, for exam\u00adple, may play a role. <\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Cer\u00adtain med\u00adica\u00adtions can impair sperm pro\u00adduc\u00adtion or sex\u00adu\u00adal func\u00adtion.

As a result, sperm pro\u00adduc\u00adtion can decrease marked\u00adly or come to a com\u00adplete stop. After dis\u00adcon\u00adtin\u00adu\u00ada\u00adtion, sperm pro\u00adduc\u00adtion often recov\u00aders, but this can take sev\u00ader\u00adal months and is not always ful\u00adly pre\u00addictable. Oth\u00ader med\u00adica\u00adtions can also affect male fer\u00adtil\u00adi\u00adty and should be tak\u00aden into account in the med\u00adical his\u00adto\u00adry in cas\u00ades of an unful\u00adfilled wish to have a child. <\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n

Lifestyle and exter\u00adnal influ\u00adences can also affect male fer\u00adtil\u00adi\u00adty. Smok\u00ading, severe over\u00adweight, exces\u00adsive alco\u00adhol con\u00adsump\u00adtion, and drug use<\/strong> can be asso\u00adci\u00adat\u00aded with reduced sperm qual\u00adi\u00adty.

In prin\u00adci\u00adple, men can remain fer\u00adtile into old\u00ader age. How\u00adev\u00ader, with increas\u00ading age, sperm qual\u00adi\u00adty<\/a> and sperm DNA integri\u00adty can change, which may reduce the like\u00adli\u00adhood of preg\u00adnan\u00adcy. At the same time, the risk of new\u00adly occur\u00adring genet\u00adic changes in sperm increas\u00ades. Over\u00adall, the influ\u00adence of age on fer\u00adtil\u00adi\u00adty is less pro\u00adnounced in men than in women. <\/p>\n<\/div>\n<\/div>\n<\/div>\n\n\n\n
