The menstrual cycle is a natural process that occurs in the female reproductive system, typically lasting around 28 days on average, although it can vary from woman to woman and cycle to cycle. It involves a series of hormonal and physiological changes that prepare the body for pregnancy. Here are the key phases of the menstrual cycle:
- Menstruation (Days 1-5): The cycle begins with menstruation, which is the shedding of the uterine lining (endometrium) that occurs when an egg released during the previous cycle was not fertilized. Menstruation typically lasts around 3 to 7 days.
- Follicular Phase (Days 1-13): During this phase, the pituitary gland in the brain releases follicle-stimulating hormone (FSH), which stimulates the ovaries to produce several follicles, each containing an egg. These follicles start to mature, but usually, only one becomes dominant.
- Ovulation (Around Day 14): Ovulation is the release of a mature egg from the dominant follicle in the ovary. This usually occurs around the middle of the menstrual cycle, approximately 14 days before the start of the next menstrual period. Ovulation is triggered by a surge in luteinizing hormone (LH), which causes the follicle to rupture and release the egg into the fallopian tube, where it can potentially be fertilized by sperm.
- Luteal Phase (Days 15-28): After ovulation, the empty follicle transforms into a structure called the corpus luteum, which secretes progesterone and some estrogen. These hormones help prepare the uterine lining for potential implantation of a fertilized egg. If fertilization does not occur, the corpus luteum breaks down, leading to a decline in hormone levels, and the menstrual cycle begins again with menstruation.
