Abstract
Ramadhan fast did not have any adverse effect on the fertility of healthy men. In fact there were some suggestions that fasting improves the total sperm count, the gonadotrophic hormone levels, and the testosterone level in fertile males. Fasting does not either improve or decrease the seminal quality of azoospermics but may have some effect on oligozoospermics. There was a beneficial effect of the Ramadhan fast on spermatogenesis, either via the hypothalamo-pituitary-testicular axis or by a direct effect on the testis.
