- Follicular phase ( before release of the egg)
- Ovulatory phase (egg release)
- Luteal phase (after egg release)
The menstrual cycle has three phases:
Follicular phase: follicular phase is also known as the proliferative phase. The follicular phase begins on the first day of menstrual bleeding. The follicular phase begins on day one which is characterized by the one set of mensuration and continuous today 14 (ovulation) of a typical 28 days cycle.
Ovulatory Phase: Ovulation is the process in which a mature egg is released from the ovary. Ovulation is a phase in the menstrual cycle when your ovary release and egg (ovum). Once an egg leaves your ovary, it travels down your fallopian tube where it waits to be fertilized by sperm on average, it happens on day 14 of a 28 day before cycle.
Luteal Phase: the luteal phase is typically fixed at approximately 14 days (days 14 to 28) and it is characterized by changes to harmon’s levels. Such as an increase in progesterone and estrogen levels and Decrease in Gonadotropins in such as follicle stimulating hormones and luteinising hormones and change to the endometrial lining to promote implantation of the fertilized egg.
Which hormones are responsible for the menstrual cycle?
