How many eggs do I have? The number of oocytes (eggs) a woman has reaches a maximum of approximately 8 million when she was a 20 week fetus. By the time that woman reaches puberty approximately 500 oocytes remain. Oocytes are lost every day in a process known as atresia. In some women this process […]
Anti-Mullerian Hormone or AMH is secreted by ovarian granulosa cells and is a useful marker for the ovarian response to gonadotropin stimulation in women having IVF. A recent study reported that low AMH levels are associated with miscarriage following IVF. The study, which was reported at the October 2016 meeting of the American Society for […]
Many women are not ready to conceive but are very curious about their fertility status. In today’s society, women often delay childbearing until later in their reproductive years. The reasons for this shift are complex, but are often related to social, educational, and economic factors. This trend toward delayed childbearing has resulted in an increased number of women […]
Ovarian Reserve Markers
Ovarian reserve is a term that is used to determine the capacity of the ovary to provide eggs that are capable of fertilization resulting in a successful pregnancy. Several noninvasive ovarian reserve markers have been proposed to assess ovarian reserve including serum levels of follicle stimulating hormone (FSH), serum anti-mullerian hormone (AMH), luteinizing hormone, estradiol, […]
Thinking About Freezing Your Eggs?
Are you thinking about freezing your eggs? Growing awareness of a woman’s biological clock has resulted in a surge of interest in fertility preservation. Many reproductive-aged women are now taking control of their fertility and freezing their eggs. Did you know that a simple blood test can give you valuable information about your current pool of eggs? A […]
Do I Still Have Healthy Eggs?
Do I still have healthy eggs is a question that many infertile women ask, particularly those who are over 35 years of age. Most women today are aware that fertility declines after age 30 and significantly declines after age 35. While this is true, most women remain very fertile till age 39. Certainly after age […]
The American Society of Reproductive Medicine (ASRM), the professional committee for experts in reproductive endocrinology and infertility medicine, put out a committee opinion this month on testing and interpreting measures of ovarian reserve. A woman’s eggs, or oocytes, are the greatest when she is a fetus and decline in number as she ages. Ovarian reserve […]
Anti-mullerian hormone (AMH), also known as mullerian inhibiting substance, is a regulatory protein found in the ovary. It is synthesized in the granulosa cells of antral follicles (see drawing below). AMH is thought to play a role in coordinating follicular development within the ovary; there is a “give and take” between follicle stimulating hormone (FSH) […]
