What effect does fever have on male fertility? The andrologist answers

Many women write concerned about the effect that fever or medications taken to lower it may have on male fertility.

First of all, the effects of the altered temperature are feared. We are well aware that spermatogenesis takes place in optimal conditions if the temperature is 35°C (for this reason the testicles are located outside the body). A body temperature of 37°C would already be too much.

The effects that antibiotic treatments can have on the quality of the spermatozoa are also worrying. When a man has a fever or is taking medication, should the couple continue to search for a child if those are the fertile days? Or is it the case to skip the month? Can the antibiotics taken in any way cause problems for the formation of the fetus in case of conception?

Here is the answer from our andrologist, Dr. Mario Torino Medical Director at ULSS 15:

On the other hand, the correlation between hyperthermia (as in the case of fever) and a reduction in the motility, number and vitality of the spermatozoa has been demonstrated , which can last up to 3 months, corresponding to a complete cycle of spermatogenesis.
My advice is therefore to calmly have intercourse again this month and in case of failure, carry out a seminal fluid test the following month to re-evaluate your husband’s fertility.
