Protocol Number: 00-CH-0189
Women with normal ovarian function ages 18 to 55 and postmenopausal women 60 years of age or older may be eligible for this study. Candidates will be screened with a medical history, physical examination, blood tests and vaginal ultrasound examination. For the ultrasound study, a probe that emits sound waves is inserted into the vagina, and the sound waves are converted to form images of the ovaries. The procedure is done with an empty bladder and takes about 10 minutes. After this screening visit (Visit 1), those enrolled in the study will return to the NIH Clinical Center for the following additional procedures: Visit 2-Will be scheduled between days 3 and 5 of the menstrual cycle (for women who are still menstruating). Participants will have blood tests to measure hormone levels and to check for pregnancy, and will have another transvaginal ultrasound examination. They will then receive an injection of a synthetic form of follicle stimulating hormone (FSH), a hormone the body makes normally. Visits 3 and 4-Will be scheduled 24 and 36 hours after the FSH injection given during Visit 2 for collection of blood samples. Visit 5-Will be scheduled 48 hours after the FSH injection for additional blood sampling and a final transvaginal ultrasound examination.
