WHAT DOES MALE FERTILITY DEPEND ON?
Male fertility depends on the quality of sperm. It is affected by the number of sperm, morphology and movement properties. In the case of infertile couples, infertility can be traced back to male or female origin in 40-40%.
If the sperm count is low, less sperm reaches the egg in natural conditions. If there is an abnormality in the sperms' movement properties or in morphology, the chance of survival in the female genital organ is reduced, or it is more difficult to reach the ovum.
In some cases, the lack of conception can be traced back to immunological causes. Women's immune system can produce antibodies against her partner's sperm, and in some cases men's own organism can produce antibodies against his own sperms. This leads to aggregation or destruction of sperms, thereby inhibiting their fertilizing capacity.
