Couples wishing to have children should have sex at 7:30 am, since the sperms of the man are then optimally active. This is true not only for couples who opt for natural fertilization, but also for partners who follow an in vitro fertilization trajectory, say researchers at the University Hospital Zurich. This brings back the Telegraaf.
Scientists examined more than 12,000 sperm samples of more than seven thousand men. Spermatozoa are of good quality, especially in summer. "In the early morning, sperm quality is highest, and anyone who uses it can increase both natural fertility and IVF fertility," explains Brigitte Leeners, senior researcher at Sun.
This n & # 39; This is not the first time researchers say that 7:30 am is the best time to have sex, but other studies have also led to different conclusions, says the principal investigator. Spermatozoa are in good shape late in the afternoon.
