Study Notes
Female Reproductive System
- Consists of both internal and external organs
- Functions include:
- Production of female sex hormones
- Facilitating sexual intercourse
- Enabling fertilization
- Supporting pregnancy and childbirth
Female Organs
- Ovaries: Produce eggs (ova) and hormones like estrogen and progesterone.
- Fallopian Tubes: Transport eggs from the ovaries to the uterus. Fertilization typically occurs here.
- Uterus: Womb, where a fertilized egg implants and develops during pregnancy.
- Endometrium: Uterine lining, thickens in preparation for pregnancy and sheds during menstruation if fertilization doesn't occur.
- Cervix: Lower part of the uterus, opens into the vagina. Allows the passage of menstrual blood, sperm, and baby during childbirth.
- Vagina: Muscular canal connecting the cervix to the outside of the body. Serves as the birth canal and exit for menstrual flow.
Male Reproductive System
- Consists of both internal and external organs
- Functions include:
- Production of male sex hormones
- Generating and transporting sperm
- Facilitating sexual intercourse
Male Organs
- Penis: External organ for sexual intercourse and urination. Includes the shaft, glans (head), and urethra.
- Scrotum: Sac holding and protecting the testicles, ensuring optimal temperature for sperm production.
- Testicles (Testes): Produce sperm and testosterone, the primary male sex hormone.
- Epididymis: Coiled tube where sperm mature and are stored.
- Vas Deferens: Tubes transporting mature sperm from the epididymis to the urethra for ejaculation.
- Seminal Vesicles: Produce seminal fluid, which mixes with sperm to form semen.
- Prostate Gland: Produces fluid that nourishes and protects sperm, contributing to semen.
- Urethra: Tube carrying urine from the bladder and semen from the reproductive system out of the body through the penis.
Spermatozoa
- Manufactured in the testicles and stored there and in the epididymis.
- Travel up the vas deferens, passing the seminal vesicles and prostate gland.
- Most of the ejaculate fluid comes from the seminal vesicles and the prostate gland.
- Travel through the penis and are released by ejaculation.
Testosterone
- Primarily produced in the testicles.
- Crucial for development of male reproductive tissues like the testicles and prostate.
- Responsible for secondary sexual characteristics during puberty, including increased muscle and bone mass.
- Essential for spermatogenesis (sperm production).
- Maintains the health and function of male reproductive organs.
- Influences libido, fat distribution, muscle mass and strength, and red blood cell production.
The Female Reproductive Cycle (Menstrual Cycle)
- A complex series of events preparing the body for pregnancy each month.
- Begins in the ovaries, with follicles containing immature eggs developing.
- Follicular Phase: Driven by FSH (follicle-stimulating hormone). Follicles grow and produce estrogen, thickening the uterine lining.
- Ovulation: Surge in LH (luteinizing hormone) triggers the release of a mature egg from the ovary.
- Luteal Phase: Ruptured follicle transforms into the corpus luteum, which secretes progesterone. This further prepares the uterine lining for implantation.
- Menstruation: If fertilization doesn't occur, the corpus luteum breaks down, causing a drop in progesterone and estrogen. The uterine lining sheds, and the cycle restarts.
