Study Notes
Male Reproductive System
- Primary Function: Spermatogenesis (production of sperm)
- Location of Spermatogenesis: Seminiferous tubules within the testes
-
Sperm Maturation: Occurs in the epididymis located on the posterior side of the testes
- Maturation involves: Growth of a tail for swimming and production of enzymes to penetrate the oocyte (egg)
- Sperm Transport: From the epididymis, sperm travels through the vas (ductus) deferens to the ampulla (pouch posterior to the urinary bladder where sperm is stored)
- Ejaculation Pathway: Sperm is released into the prostatic urethra, a section of the urethra within the prostate
-
Seminal Fluid Production:
- Seminal vesicles (posterior to the urinary bladder, adjacent to the ampulla)
- Prostate (inferior to the urinary bladder within the pelvic cavity)
- Cowper's glands (inferior to the prostate)
- Erection: Stimulated by the parasympathetic nervous system, causing penile arteriole dilation
- Ejaculation: Stimulated by the sympathetic nervous system
Female Reproductive System
- Primary Function: Oogenesis (production of oocytes)
- Location of Oogenesis: Ovaries, specifically within ovarian follicles
-
Follicle Development: Each month, one follicle matures beyond others, becoming the Graafian follicle
- This development is stimulated by follicle-stimulating hormone (FSH)
-
Ovulation: Occurs on day 14 of a woman's cycle, triggered by a surge in luteinizing hormone (LH)
- The empty follicle becomes the corpus luteum
-
Egg Transport: The ovulated egg travels down the fallopian tubes to the uterus
- The uterus is located superior/posterior to the urinary bladder and anterior to the rectum
- Childbirth: During delivery, the cervix (neck of the uterus, projecting into the vaginal canal) dilates
Female Reproductive Cycle
-
Menstrual Phase (Day 1-5ish): First day of bleeding marks day 1
- All reproductive hormones are at their lowest levels, except for FSH
- Preovulatory Phase (Day 5-14): FSH and estrogen (building the uterine lining) levels increase, LH levels start to rise
- Ovulation (Day 14): Surge in LH triggers ovulation
-
Postovulatory Phase/Luteal Phase (Day 14-28): Estrogen and progesterone levels increase to prepare for potential pregnancy
- If pregnancy occurs, these hormones remain elevated
- If not, these hormones decline, triggering the next menstrual cycle
Male Reproductive System
- Primary function: Spermatogenesis (production of sperm)
- Spermatogenesis location: Seminiferous tubules within the testes
-
Sperm maturation: Occurs in the epididymis, located on the posterior side of the testes
- Includes growth of a tail for swimming and production of enzymes to penetrate the oocyte (egg)
-
Sperm transport: From the epididymis, sperm travels through the vas deferens (ductus deferens) to the ampulla
- Ampulla is a pouch located posterior to the urinary bladder (UB) where sperm is stored
- Ejaculation: Sperm is released into the prostatic urethra, a section of the urethra within the prostate gland
-
Seminal fluid production: Three glands contribute to seminal fluid:
- Seminal vesicles: located on the posterior side of the UB, next to the ampulla
- Prostate gland: inferior to the UB within the pelvic cavity
- Cowper's glands: inferior to the prostate gland
- Erection: Stimulated by the parasympathetic nervous system, which causes dilation of penile arterioles
- Ejaculation: Stimulated by the sympathetic nervous system
Female Reproductive System
- Primary function: Oogenesis (production of oocytes)
- Oogenesis location: Ovaries, specifically within ovarian follicles
-
Ovarian follicle maturation: Each month, one follicle matures beyond the others, becoming a Graafian follicle
- This development is stimulated by follicle-stimulating hormone (FSH)
-
Ovulation: Occurs on day 14 of a woman's menstrual cycle
- Triggered by a surge in luteinizing hormone (LH)
- The empty follicle becomes the corpus luteum
- Ovulated egg transport: Travels down the fallopian tubes towards the uterus
- Uterus location: Superior/posterior to the UB, anterior to the rectum
- Cervix: The neck of the uterus, projects into the vaginal canal; dilates during delivery
Female Reproductive Cycle
-
Menstrual phase: Days 1-5ish, including the first day of bleeding
- All reproductive-related hormones are at their lowest levels except FSH
-
Preovulatory phase: Days 5-14
- Increased levels of FSH and estrogen (rebuilding uterine lining)
- Rising LH levels
- Day 14: LH surge triggers ovulation
-
Post-ovulatory phase (luteal phase): Days 14-28
- Elevated estrogen and progesterone levels prepare for potential pregnancy
- If pregnancy occurs, these hormone levels remain elevated
- If pregnancy does not occur, hormone levels drop, triggering the next menstrual cycle

-
Seminal Fluid Production: Three glands contribute to seminal fluid production:
- Seminal vesicles (posterior to the urinary bladder, near the ampulla).
- Prostate (inferior to the urinary bladder within the pelvic cavity).
- Cowper's glands (inferior to the prostate).
- Erection: Stimulated by the parasympathetic nervous system, causing dilation of penile arterioles.
- Ejaculation: Stimulated by the sympathetic nervous system.

Postovulatory Phase/Luteal Phase (Days 14-28):
- Estrogen and progesterone levels elevate to prepare the uterus for pregnancy.
- If pregnancy occurs, these hormones remain elevated.
