Study Notes
Reproductive System Overview
- Primary sex organs in females are called ovaries.
- Primary sex organs in males are called testes.
Male Reproductive System
- The glans penis contains the urethral orifice.
- The scrotum is a highly pigmented, muscular sack that regulates the temperature of the testes.
- The testes hang exteriorly in the scrotum to keep the temperature of the testes 3ºC below body temperature.
- Spermatogenesis starts at puberty and takes 64 days to complete.
- Spermatozoa are 85,000 times smaller than the ovum.
- The ductus deferens is lined with pseudostratified epithelium and very thick smooth muscles in the walls to propel sperm out of the body during ejaculation.
- Semen is not composed of 95% sperm and 5% seminal fluids; instead, it is composed of seminal fluids secreted from the seminal vesicles, prostate gland, and bulbourethral glands, with a small percentage of sperm.
Female Reproductive System
- The ovaries are held in place by ligaments called mesovarium, broad ligament, suspensory ligament, and ovarian ligament.
- The ovarian cycle is usually a 28-day cycle and is regulated by hormones.
- At puberty, a few primordial follicles become primary follicles with thicker layers of cells in each cycle.
- Per cycle, only one tertiary follicle can develop to ovulation, the rest undergo breakdown.
- The uterine tubes are also called Fallopian tubes.
- The uterus supports and protects the developing embryo/fetus.
- The vagina functions as an exit from the uterus during menses and childbirth.
- The mucin-secreting glands in the cervix nourish sperm and liquefy semen.
- The areolar glands in the breasts produce milk for lactation.
Hormones and Development
- The hypothalamus and pituitary gland activate the gonads to produce sex hormones and develop gametes during puberty.
- Sexual differentiation in humans occurs during the 6th week of embryonic life.
- The presence of the SRY gene on the Y chromosome determines sexual differentiation.
- The SRY gene can be determined by a genetic test before week 10 of pregnancy.
Pregnancy and Cancer
- Ectopic pregnancy occurs when the zygote implants in the fallopian tube, not the uterus.
- Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland.
- The main treatment for prostate cancer is not radiotherapy.
- Both ovarian and cervical cancer can cause vaginal bleeding and pelvic pain.
