Study Notes
Male Reproductive System
- Sperm production occurs in the seminiferous tubules of the testes.
- The pathway for spermatozoa: seminiferous tubules → efferent ductules → rete testes → epididymis → ductus deferens → ejaculatory duct → urethra.
- The primary male gonad responsible for gamete production is the testis.
- The cremaster muscle facilitates the movement of the testes toward the body for temperature regulation.
- Spermatogonia are the stem cells found in the seminiferous tubules.
- Meiosis transforms a primary spermatocyte into a secondary spermatocyte.
Female Reproductive System
- During ovulation, a secondary oocyte is released from the ovaries.
- The endometrium is the uterine layer that undergoes significant changes during the menstrual cycle and is shed if fertilization does not occur.
- Testosterone is produced by interstitial cells, stimulated by luteinizing hormone.
- The majority of semen volume, approximately 60%, is produced by the seminal vesicles.
Reproductive Health and Function
- Testicular cancer is the most common cause of cancer-related fatalities in men aged 15 to 35.
- The ovaries are the primary gonads of the female reproductive system, responsible for producing oocytes.
- The unique function of the female reproductive system is to protect and support a developing embryo.
- The ovaries do not secrete FSH (Follicle Stimulating Hormone).
Development and Fertilization
- Primary oocytes in females are formed between the third and seventh month of fetal development.
- Ovulation marks the transition from the follicular phase to the luteal phase in the ovarian cycle.
- Fertilization occurs in the ampulla of the uterine tube.
- The vagina does not participate in fertilization of oocytes but serves other functions.
Functions and Structures
- The vagina serves to:
- Receive the penis during intercourse.
- Provide a passage for childbirth.
- Eliminate menstrual fluids.
- Hold spermatozoa post-intercourse.
- The clitoris contains erectile tissue similar to corpora cavernosa and corpora spongiosum found in males.
- The mammary glands provide nourishment during infancy.
- The most prevalent reproductive system cancer in women aged 15 to 34 is cervical cancer.
Contraception and Sterilization
- The only birth control method proven to effectively protect against STDs is the male condom.
- Spermiogenesis refers to the maturation process that spermatozoa undergo to become fully functional.
- Male sterilization involves cutting and cauterizing the ductus deferens, preventing sperm from entering the ejaculate.
Additional Anatomic Features
- The infundibulum of the uterine tube contains fimbriae that help guide the oocyte.
- The prominent folds of the female external genitalia are referred to as the labia.
- The distal end of the penis is known as the glans.
- Erection occurs due to the dilation of arterial blood vessels.
