According to the new study results, the combination of two fertility drugs: Femara (letrozole) and follicle-stimulating hormone (FSH) could be of benefit in older women undergoing intrauterine insemination.
In infertile women, FSH is often used to stimulate the ovaries to produce several eggs, followed by intrauterine insemination (injection of sperm into the uterus).
Dr. Mohamed A. Bedaiwy and colleagues from the Toronto Center for Advanced Reproductive Technologies, Toronto, took a look back at a group of infertile women aged 40 and older who had controlled ovarian stimulation using FSH alone or in combination with Femara, followed by intrauterine insemination.
The researchers reported that the pregnancy rates were comparable in the two groups with seventeen of 90 women (18.9%) in the Femara/FSH arm and 13 of 69 (18.8%) in the FSH only arm became pregnant.
