Objective:
The goal of this work is to expand the usefulness of antimüllerian hormone (AMH) in predicting in vitro fertilization cycle outcome by demonstrating that AMH concentration obtained in an ongoing treatment cycle predicts both oocyte number and pregnancy.
Study Design:
Serum samples were obtained from 190 in vitro fertilization patients at onset of follicle-stimulating hormone stimulation. These were analyzed retrospectively during a single cycle in which clinicians were blinded to the results. Our major outcome measures were the number of oocytes obtained and ongoing pregnancy.
Results:
Patients with an initial AMH concentration of >3 ng/mL were found to produce a mean of 19.8 oocytes and had an ongoing pregnancy rate of 60.3%. In contrast, those with AMH values of ≤1 ng/mL yielded a mean of 6.2 oocytes and had an ongoing pregnancy rate of 23.4% (P < .0001 for both).
Conclusion:
Greater AMH serum concentration strongly predicts an increased number of oocytes and ongoing pregnancy (P ≤ .0001).

Ovarian Cycle
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
