Did you know ? When the child is late announcing, one third of the complications are due to male factors, another third to female factors and the rest is a combination of both or unexplained factors.
Infertility: women not alone involved
- For centuries, socially and culturally, male infertility was poorly accepted. Inconceivable to think that it was not accompanied by sexual disorders, that the fertility of men was unrelated to their virility! Only their companions consulted. So, it was consensually recognized that the difficulties or even the impossibility to have a child, were their responsibility!
- The advent of knowledge in procreative medicine has put an end to popular ideas that had a hard tooth! Now, when the child is late announcing, it is admitted that one-third of the complications are due to male factors, another third to female factors and the rest is to a combination of both or to factors that may remain unexplained. Today, technologies in reproductive health care, AMP, are as much interested in the causes of infertility in men as in women to try to provide solutions.
The different physiological causes to male infertility
The reasons for difficulty in conceiving a child have several factors in men.
- In some cases, they are explained by abnormalities of their gametes, the reproductive cells. Malfunctions in the production or behavior of spermatozoa are diagnosed by a medical examination called the spermogram. An insufficient amount - oligospermia -, a total absence - azoospermia -, a lack of mobility, - asthenospermia - or a high number of dead spermatozoa - necrospermia - are likely to affect the reproduction process and lead to infertility or even sterility.
- Nevertheless, it is possible that it has other origins: mechanical, infectious or genetic. Can be involved a cryptorchidism - no descent of the testicles - a varicocele - dilation of the spermatic veins - sequelae of viral infections such as mumps, a sexually transmitted infection.
- Exposures to endocrine disruptors, but also the consumption of alcohol and tobacco or the Klinefelter syndrome, a chromosomal anomaly, are sometimes involved. This type of diagnosis is made only after various examinations such as blood tests, ultrasounds or biopsies.
- However, in about 30% of cases, no specific explanation is found for male infertility.
