New research from the Michigan State University's College of Human Medicine has revealed that women who opt for multiple cycles of infertility treatments may have increased chances of conceiving and maintaining a successful pregnancy. Continued in-vitro fertilization seems to improve fertility over time. This can be encouraging for women who are trying to conceive, as many women stop after one or two cycles due to the stress that the procedure can cause. However, multiple factors can still affect the success rate. Older women with underlying medical conditions may have more trouble conceiving or successfully carrying a pregnancy to term even after several rounds of IVF if they are using their own eggs. 

Success Rates

Because that success rate tends to be quite low if women over 40 use their own eggs, then they may choose to find a younger woman who can donate their eggs to them. It seems that positive birth outcomes are increasing due to the higher number of women opting for donated eggs. This is because donors tend to be younger, with an average age of 28, and their ovaries and eggs may be in better health than those of an older woman. A study performed at the Emory School of Medicine that good birth outcomes increased in correspondence with the increase in the use of donated eggs. This increased in donated eggs may be due to the fact that egg donation can be quite lucrative for the donor despite the medical risks involved. Young donors in good health can be paid anywhere from $4,000 to 10,000 per donation cycle. With the demand for young egg donors increasing as older women's ovarian reserves grow smaller or become unviable, it makes sense that donation cycles would go from 10,081 in 2000 to 18,306 in 2010.

Ideal IVF Donors

Regardless of how or why egg donation has increased, it seems to signal that women using IVF for multiple cycles can still have successful birth outcomes at any age before they reach menopause. As long as donors are under the age of 35, the chances of a successful birth outcome on the part of the recipient are very good indeed. It is certainly an exciting time not only for reproductive health specialists and researchers, but for women and couples who are struggling with infertility.
