Recently this fall I had a woman come in who was undergoing IVM. She orginally heard of the procedure in Canada where she had been living. I had not had a couple undergo this procedure but basically it is IVF without the drugs instead is done with the use of hormones similar to what the body makes. The RE's will utilize HCG made in a lab but similar to the hormone circulating in every pregnant woman. This hormone is similar to LH which drives the follicles to develop. LH causes maturity and the dominant follicle usually releases quite a bit of it. HCG causes immature eggs to stimulate towards final maturation.
Last night I had the opportunity to listen to Dr. Karol Chacho MD one of the first doctor's in the US to utilize IVF in Chicago, talk about this procedure. He was very excited about the procedure with less risks to women, less overstimulation of the ovaries, less risks of cancer. Several centers around the US he stated are jumping on this bandwagon. Ovarian hyperstimulation causes the ovaries to enlarge and often rupture, these large ovaries leave blood thick and can hypercoagulate causing clogged arteries or a clot in the brain or legs.
He also strongly reccommended patients get pretreated with acupuncture and Chinese Herbs before IVM to improve their success rate.
