Com\u00admon cau\u00adses of an unful\u00adfil\u00adled wish to have a child<\/h2>\n\n\n\n

An unful\u00adfil\u00adled wish to have a child affects many cou\u00adples: Around one in six cou\u00adples do not beco\u00adme pregnant natu\u00adral\u00adly within a year. The cau\u00adses are varied\u2014and they may lie with the woman, the man, or both tog\u00ade\u00adther.
Seve\u00adral fac\u00adtors often interact\u2014and some\u00adti\u00admes the initi\u00adal exami\u00adna\u00adti\u00adons do not show any abnor\u00admal fin\u00addings at first.
 
If pregnan\u00adcy does not occur over a lon\u00adger peri\u00adod, it can the\u00adr\u00ade\u00adfo\u00adre make sen\u00adse to cla\u00adri\u00adfy pos\u00adsi\u00adble cau\u00adses in a tar\u00adge\u00adted way. It is not always neces\u00adsa\u00adry to wait for a spe\u00adci\u00adfic peri\u00adod first: In cases of cycle dis\u00ador\u00adders, known pre-exis\u00adting con\u00addi\u00adti\u00adons, or other indi\u00adca\u00adti\u00adons of redu\u00adced fer\u00adti\u00adli\u00adty, ear\u00adlier eva\u00adlua\u00adti\u00adon may also be advi\u00adsa\u00adble. <\/p>\n\n\n\n

For sound dia\u00adgno\u00adstics, it is cru\u00adcial to invol\u00adve both part\u00adners equal\u00adly. Fer\u00adti\u00adli\u00adty dis\u00ador\u00adders can have dif\u00adfe\u00adrent causes\u2014hormonal, func\u00adtion\u00adal, struc\u00adtu\u00adral, or gene\u00adtic. Howe\u00adver, it is not always pos\u00adsi\u00adble to iden\u00adti\u00adfy a sin\u00adgle cause\u2014often a more com\u00adple\u00adte pic\u00adtu\u00adre only emer\u00adges from the inter\u00adac\u00adtion of various fac\u00adtors. <\/p>\n\n\n\n

As a result, sperm pro\u00adduc\u00adtion can decrease mark\u00aded\u00adly or come to a com\u00adple\u00adte stop. After dis\u00adcon\u00adti\u00adnua\u00adtion, sperm pro\u00adduc\u00adtion often reco\u00advers, but this can take seve\u00adral months and is not always ful\u00adly pre\u00addic\u00adta\u00adble.

In prin\u00adci\u00adple, men can remain fer\u00adti\u00adle into older age.

At the same time, the risk of new\u00adly occur\u00adring gene\u00adtic chan\u00adges in sperm increa\u00adses.
