Although embryo transfer (ET), the final step of in vitro fertilization (IVF), is intended to facilitate accurate embryo implantation in the uterine cavity, tubal ectopic pregnancy (TEP) is twice more common following IVF compared to natural conception. Now, a recent study published in the Journal of Assisted Reproduction and Genetics states that a positive history of TEP significantly enhances the incidence of repeated ectopic pregnancies in women undergoing IVF-ET treatment.

In Tough Economy, Don't Delay IVF
Media campaigns have been launched, books have been written, yet the age at first marriage continues to increase and the number of couples who delay childbearing. This is especially true in tough economic times due to the substantial cost of raising a child. "Couples who decide to delay marriage and child-bearing, don't fully comprehend the ramifications of their actions," according to parenting expert and columnist Dr. Alan Singer.
The classic, unproven dogma that ovarian endometrioma should be removed in all infertile women prior to IVF has been recently questioned. There is currently insufficient data to clarify whether the endometrioma-related damage to ovarian responsiveness precedes or follows surgery.
The shape of a protein that forms a key coating on an egg provides an atomic view of conception.
If fertility had a shape, this would be it.
Scientists have figured out the exact shape of part of a protein that sits on the outside of the egg and aids in fertilization. The results, which may ultimately lead to new contraceptives and treatments for infertility, appear in the Dec. 4 Nature.
For nearly 15 years, Kim and Walt Best have been paying about $200 a year to keep nine embryos stored in a freezer at a fertility clinic at Duke University — embryos that they no longer need, because they are finished having children but that Ms. Best cannot bear to destroy, donate for research or give away to another couple.
The embryos were created by in vitro fertilization, which gave the Bests a set of twins, now 14 years old.
Scientists at the University of Liverpool have identified an enzyme that could be responsible for a condition called endometriosis -- the most common cause of pelvic pain in women
Endometriosis is a condition whereby patches of the inner lining of the womb appear in parts of the body other than the womb cavity. It can cause severe pain and affects approximately 15% of women of reproductive age. Endometriosis is also associated with infertility, with 50% of infertile women affected by the condition.
