So l’ve been researching a lot on this topic and l’ve come across a lot of articles that actually support this theory. In fact, there’s an ongoing debate over yams between natural/ Chinese practitioners and western medicine. The former maintain that yams should only be eaten in the first half of the menstrual cycle, from menstruation until ovulation. After ovulation, eating yams is not recommended because it is believed that the phytoestrogens in them can counteract the effects of estrogen on the cervical fluid and make it too sticky for the transport of sperm.
According to Wikipedia, the tubers of certain wild yams like Kokoro-native to Western Nigeria, Benin and Togo-are a source for the extraction of diosgenin which is used for the commercial synthesis of progesterone and other steroid products. Now natural practitioners believe that wild yams taken in the first two weeks of a menstrual cycle improves fertility by converting diosgenin into two other hormones essential for ovulation, luteinizing hormone and follicle stimulating hormone (FSH). Endometriosis, as we all know, is linked to estrogen dominance in the body. Natural practitioners believe that the phytoestrogens and progesterone like properties in yams can help regulate the estrogen-progesterone balance. In theory, the natural progesterone in yams can help extend the luteal phase in women whose corpus luteum doesn’t produce enough progesterone in early pregnancy.
Western medicine, on the other hand have rejected this theory and doctors at the University of Maryland have actually stated that the human body lacks the enzymes to convert wild yams into usable progesterone.
Hence, the jury is still out on yams but l must say l’m going with the Chinese practitioners’ views on this one. I’m sorry to say l didn’t find any relief with Western medicine; l only ended up with scars, a blocked tube, more ovarian cysts and multiple operations. Traditional Chinese medicine on the other hand, have been around for over 3000 years and counting so they must be doing something right. They have helped sufferers with different ailments that have lost hope in modern medicine ( my opinion, l stand to be corrected) and if they say there’s just the slightest chance that yams could help with conception (and l’m backing this up with Yorubas having the highest twinning rate in the world as a result of yams) , then l’m definitely up for it!
Thanks for reading and have a blessed week.
