The Real Benefits of Knowing Your Menstrual Cycle Hormones

What are the menstrual cycle hormones and how does it work? The first day of a menstrual cycle always coincides with the start of menstrual bleeding and lasts until the day before the first day of the following menstruation. A typical cycle is 28 days long, with lengths typically varying slightly around this number.

However, every woman knows that hormones during menstrual cycle lengths can vary greatly from woman to woman. In extreme cases, there can be time spans of 90 days without any particular reasons between two periods.

Hormones and Menstrual Cycle

Every menstrual cycle is then subdivided into several phases in which the female reproductive organs prepare for pregnancy. Menstrual cycle hormones are determined and controlled by different levels of hormones that are essential to female health.

Given that menstruation itself is considered the first phase and lasts (on average) 4 days, the so-called follicular phase takes part between day 5 and day 13 of your menstrual cycle. Among other hormones, the FSH (follicle-stimulating hormone) induces the production of an egg in the ovaries, while others – mainly estrogen, the most important “female” hormone – induce the lining of the uterus to grow. This happens to provide the best conditions for a potentially fertilized egg that is to nest in the uterus.

Around the middle of the cycle – that is day 14 in case of an average 28-day cycle – the ovary will release an egg. Sometimes, two eggs are released by both ovaries – this will most probably lead to fraternal twins in case of fertilization.

Menstrual Cycle Phases

The following luteal phase is marked by the egg traveling down the fallopian tube, ready to be fertilized by a sperm cell. In case there is no fertilization, hormones and menstrual cycle levels will drop significantly around day 25 of the menstrual cycle.

This in turn makes the unfertilized egg fall apart and induces the repulsion of the previously built lining in the uterus. In other words, the next period is triggered at this point, and the menstrual cycle is over.
