While using a vaginal suppository form of the drug, which was developed by Dr. Sher, three out of four of the women became pregnant. Tests showed the women experienced an improvement in uterine blood flow while taking Viagra, but it is unclear whether using the drug actually led to the pregnancies. Dr. Sher's test is an initial look into Viagra's use for women, specifically in treating women with thin uterus linings. However, now it is important to conduct additional research into this use of Viagra in a controlled setting with a larger test group. News reports about Dr. Sher's study only mentioned Viagra, but women are often simultaneously given a wide variety of treatments for infertility.
Treatments can often include various fertility drugs, in vitro fertilization and surgery.
For this reason, it is often difficult to pinpoint the exact treatment that leads to pregnancies. Endocrine research into infertility continues to examine the hormonal imbalances that can cause the condition. Even today, many of the specific hormonal changes that determine the successful completion of the reproductive cycle are not fully understood and new research is aimed at providing a greater understanding of these processes. We commend Dr. Sher for his innovation, but hope that additional research, specifically placebo controlled studies, will be conducted, to determine the effectiveness of Viagra in treating infertility in women. With more than 10,000 members from 80 countries, The Endocrine Society is the world's largest and most active organization devoted to the research, study and clinical practice of endocrinology.
