AMH and Dosing Regimens for Initial IVF Stimulation Protocols

This is a research study on a hormone in women called anti-mullerian hormone (AMH) an indicator of the amount of egg reserve in the ovaries. The research involves a blood draw to determine the AMH level. This knowledge will help the investigators decide a dosage of gonadotropins, the hormones used to stimulate the production of more than one egg for use in an in vitro fertilization (IVF) cycle. The amount of gonadotropin given has to be tailored to each individual participant. The investigators can use information about the participant and the hormone levels to determine this dosage and the chances of becoming pregnant as a result of IVF treatment. The reason the investigators are doing this research is to find out if basing the gonadotropin dosage solely on the participant's AMH level will give the investigators a better result than the previous method based on age and other hormone levels.
