🟩#menstrualcycle /#menses:
The menstrual cycle is a recurring process that occurs in females of reproductive age. It typically lasts around 28 days, although it can vary for different individuals. The cycle involves the preparation of the female body for a potential pregnancy. If pregnancy does not occur, the uterine lining is shed, leading to menstrual bleeding.
🟩#oogenesis:
Oogenesis is the process by which female gametes, or eggs, are produced in the ovaries. It begins before a female is even born and continues throughout her life until menopause. It involves several stages of cell division and differentiation, resulting in the formation of a mature egg. Only a small number of eggs mature and are released during a woman's reproductive years.
🟩#fertilization:
Fertilization occurs when a sperm cell from a male penetrates an egg cell from a female. This usually happens in the fallopian tube after ovulation. The resulting fertilized egg, or zygote, contains a complete set of chromosomes (half from the mother and half from the father). The zygote begins to divide and develop into an embryo, which eventually implants itself into the uterus.
🟩Phases of the Menstrual Cycle:
1. #menstruation: The cycle begins with menstruation, during which the uterine lining (endometrium) from the previous cycle is shed. This leads to menstrual bleeding.
2. #follicular Phase: After menstruation, the body starts preparing for ovulation. Follicle-stimulating hormone (FSH) stimulates the growth of follicles in the ovaries, each containing an immature egg. These follicles produce estrogen, which thickens the uterine lining.
3. #ovulation: Midway through the cycle, a surge in luteinizing hormone (LH) triggers the release of a mature egg from one of the follicles. This egg is then available for fertilization in the fallopian tube.
4. #lutealphase: After ovulation, the empty follicle becomes the corpus luteum, which produces progesterone. Progesterone maintains the uterine lining and prepares it for possible implantation of a fertilized egg. If fertilization doesn't occur, the corpus luteum degenerates, leading to a decrease in hormone levels and the start of menstruation.
🟩Role of Female Sex Hormones:
Estrogen, primarily produced by the growing follicles in the ovaries, stimulates the growth of the uterine lining during the follicular phase. It also promotes secondary sexual characteristics and regulates the menstrual cycle. Progesterone, produced by the corpus luteum after ovulation, maintains the uterine lining and prepares the body for pregnancy by preventing further ovulation.
These hormonal changes ensure that the female reproductive system is prepared for potential fertilization and pregnancy. If fertilization does not occur, the cycle starts anew with menstruation.
