What are the main organs of the male and female reproductive systems?
The main organs of the male reproductive system are the testes, penis, vas deferens, prostate gland, and seminal vesicles. The main organs of the female reproductive system are the ovaries, fallopian tubes, uterus, vagina, and cervix.
What is the function of hormones in the reproductive system?
Hormones in the reproductive system regulate the development and function of reproductive organs, control the menstrual cycle, and support pregnancy and lactation. They are crucial for sexual development, fertility, and maintaining secondary sexual characteristics. Key hormones include estrogen, progesterone, testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH).
What are common disorders or diseases associated with the reproductive system?
Common disorders and diseases associated with the reproductive system include endometriosis, polycystic ovary syndrome (PCOS), uterine fibroids, sexually transmitted infections (STIs), prostate cancer, and erectile dysfunction.
What is the difference between gametes and zygotes?
Gametes are the reproductive cells (sperm in males and eggs in females) that contain only half the genetic material needed for a new organism. A zygote is formed when a sperm fertilizes an egg, combining their genetic material to form a single cell with a complete set of chromosomes.
What is the difference between progesterone and estrogen?
Progesterone and estrogen are two primary female sex hormones. Estrogen is primarily involved in the development of female secondary sexual characteristics and the regulation of the menstrual cycle. Progesterone prepares the uterus for pregnancy after ovulation and supports early pregnancy. Both hormones work together to regulate reproductive functions.
