The thing about ovulation
The research team from the Reproductive Biology Institute of the University of Saskatchewan was said to have overthrown what was proven for 50 years: that women have only one ovulation a month.
So far, it has been assumed that grow only once at the beginning of the cycle several follicles, from which a single fertilizable egg is produced. Indeed, in their study, the Canadian scientists found that follicles mature at two to three intervals per cycle. However, it was not found that women therefore have two to three ovulations. For their investigations, the research team had 63 women examined by ultrasound every day for a month.
Nevertheless, Dr. Roger Pierson, Director of the Reproductive Biology Institute of the University of Saskatchewan, has repeatedly cited that 40 percent of women are out of the question of natural family planning because they can ovulate at any one time. However, the study, published in the prestigious journal Fertility and Sterility, says nothing about it - only that the new findings could facilitate the treatment of infertility in women in the future. And that on the basis of the study possibly new, gentler contraceptives could be developed.
Dr. Peter Licht, Head of Gynecological Endocrinology & Reproductive Medicine at the University of Tübingen, agrees. He considers the study highly interesting - but only because it brings the new knowledge that follicles mature several times per cycle. He emphasizes, however, that this finding has "no practical relevance" because there is no question that the women repeatedly ovulated. "In rare exceptional cases, women may have two ovulations per month - but that's nothing new." Couples do not need to change their contraceptive practice because of the study.
