Hormonal Regulation of the Menstrual Cycle01:22

Hormonal Regulation of the Menstrual Cycle

2.3K
The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
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...

Hormonal Control of the Ovarian Cycle

7.6K
The ovarian cycle is meticulously regulated by the hypothalamic-pituitary-gonadal axis. This cycle orchestrates the release of a mature oocyte, essential for reproduction.
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 Phase01:18

Menses Phase

1.4K
The uterine cycle begins with the menstrual phase, which is considered day one of the cycle and typically lasts about five days. This phase is characterized by the degeneration and shedding of the stratum functionalis, the functional layer of the endometrium.
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...

The Menstrual Cycle01:19

The Menstrual Cycle

6.3K
The menstrual cycle is a recurrent sequence of changes in the uterine endometrium, specifically its functional layer, the stratum functionalis. This cycle prepares the uterus for potential pregnancy. This cycle typically spans 21–35 days, averaging 28 days, and aligns with the ovarian cycle, regulated by fluctuating levels of ovarian hormones, primarily estrogen and progesterone.
The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a...

Secretory Phase01:19

Secretory Phase

2.7K
The secretory phase of the menstrual cycle, spanning from day 14 to 28 in a typical 28-day cycle, is a period of significant physiological changes in the female reproductive system. This phase commences immediately after ovulation and is characterized by the preparation of the endometrium for potential embryo implantation.
Following ovulation, the corpus luteum, a temporary endocrine structure, produces progesterone and estrogens. These hormones stimulate the growth and coiling of endometrial...

Ovarian Cycle01:27

Ovarian Cycle

5.3K
The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle...

Area of Science:

  • Human reproductive endocrinology
  • Behavioral neuroscience
  • Olfactory communication

Background:

  • Previous research suggested women's menstrual cycles synchronize.
  • This phenomenon was hypothesized to be mediated by pheromones.
  • Recent evidence contradicts the synchronization hypothesis.

Purpose of the Study:

  • To evaluate the scientific evidence for pheromones influencing human menstrual cycle length.
  • To critically assess studies reporting such pheromonal effects.

Main Methods:

  • Systematic review of eight studies investigating pheromone effects on menstrual cycles.
  • Analysis of methodological rigor and reported findings in each study.

Main Results:

  • All eight reviewed studies exhibited significant methodological flaws.
  • No robust evidence was found to support pheromones modulating human menstrual cycle length.

Conclusions:

  • The hypothesis of pheromones regulating human menstrual cycles is not supported by current evidence.
  • Existing studies on this topic suffer from critical limitations.
  • Further research is needed to understand potential olfactory influences on human physiology.
