The menstrual cycle has three phases:
1) Menstruation - this is when bleeding occurs due to the shedding of the endometrium (the uterine lining).
2) Follicular phase - this is when the follicles develop. The follicle contains a single ovum, or egg. At the end of this phase ovulation occurs, which is when the egg is released from the follicle.
3) Luteal phase - during which the corpus luteum forms. This phase can end with either pregnancy or the degradation of the corpus luteum.

Does the menstrual cycle have four phases?
Yes, the menstrual cycle typically consists of four phases: menstruation, the follicular phase, ovulation, and the luteal phase. Each phase is regulated by hormones and plays a role in preparing the body for possible pregnancy.
What is the menstrual cycle controlled by?
The menstrual cycle is controlled by hormones, specifically estrogen and progesterone, which are produced by the ovaries. These hormones regulate the different phases of the menstrual cycle, including ovulation and menstruation. Additionally, the hypothalamus and pituitary gland in the brain play a role in controlling hormone production.
What are the 3 phases of the menstrual cycle and how do they impact a woman's reproductive health?
The three phases of the menstrual cycle are the follicular phase, ovulation, and the luteal phase. During the follicular phase, the egg matures in the ovary and the uterine lining thickens. Ovulation is when the mature egg is released from the ovary. In the luteal phase, the uterine lining continues to thicken in preparation for a possible pregnancy. If fertilization does not occur, the uterine lining sheds during menstruation. These phases impact a woman's reproductive health by regulating her menstrual cycle, fertility, and overall reproductive function. Understanding these phases can help women track their fertility and identify any potential issues with their reproductive health.
The two phases covering the first half and second half of menstrual cycle respectively?
The first half of the menstrual cycle is called the follicular phase, where the follicles in the ovaries mature and prepare for ovulation. The second half is the luteal phase, starting after ovulation, where the ruptured follicle transforms into the corpus luteum and prepares for a possible pregnancy.
What is the difference between menstruation and menstruation cycle?
Menstruation is one of the phases of the menstrual cycle, whereas the menstrual cycle is the entire reproductive system. During the menstrual cycle an egg is released and to prepare for possible pregnancy the uterus lining plumps-up, if pregnancy doesn't occur the uterus lining sheds (menstruation) so it can start afresh again next cycle.
