Objective:
To find a relationship between serum antimüllerian hormone (AMH) and follicle-stimulating hormone (FSH) levels in women with regular menstruation.
Study Design:
A cross-sectional study was conducted on 71 women with male factor infertility. Serum level of AMH and FSH and mean menstrual cycle length (MCL) were measured. The study aimed to find the correlation between serum AMH and FSH levels in normal menstrual cycles.
Results:
Our study included 71 women. Of them, 53 had an MCL of 25-35 days (group A) and 18 women had an MCL > 35 days (group B). The mean AMH in group A and group B differed significantly (4.11 +/- 3.4 ng/L, 7.42 +/- 4.34 ng/L, respectively; p < 0.008). In group A, reverse correlation between FSH and AMH was found (r = -0.32, p < 0.03).
Conclusion:
AMH level had significant difference with FSH in patients of group A who had FSH > or = 12 IU/L or FSH < 12 IU/L (1.02 +/- 0.7, 4.8 +/- 3.5 ng/L, respectively; p < 0.02). Serum AMH level with threshold of 2.2 ng/L had sensitivity of 75% and specificity of 82% in predicting FSH > or = 12 IU/L on the third day of menstrual cycle.

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.

The Menstrual Cycle
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a uterine...
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...
Menses Phase
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...
Secretory Phase
Following ovulation, the corpus luteum, a temporary endocrine structure, produces progesterone and estrogens. These hormones stimulate the growth and coiling of endometrial...
