Reproductive

Anatomy

Region: Anterior chest wall, over pectoralis major.
Key Structures: Glandular lobules → ducts → nipple; Cooper’s suspensory ligaments; lymphatic drainage mostly to axillary nodes.
Clinical Correlation: Most breast cancer drains to axillary nodes (staging); Cooper-ligament involvement → skin dimpling / peau d’orange.

High-Yield Pearl

~75% of breast lymphatic drainage goes to the axilla — the key site for cancer staging.

Region: Female pelvis.
Key Structures: Uterus (fundus/body/cervix), fallopian tubes, ovaries; broad/round/ovarian ligaments; uterine + ovarian artery supply.
Clinical Correlation: Ectopic pregnancy most often lodges in the ampulla of the tube; ovarian torsion compromises the ovarian vessels (surgical emergency).

High-Yield Pearl

The ampulla of the fallopian tube is the most common site of both fertilization and ectopic pregnancy.

Region: Scrotum and pelvis.
Key Structures: Testis → epididymis → vas deferens → ejaculatory duct → urethra; spermatic cord; prostate & seminal vesicles.
Clinical Correlation: Testicular torsion = surgical emergency (absent cremasteric reflex, high-riding testis); varicocele = “bag of worms,” usually left-sided.

High-Yield Pearl

Acute testicular pain + absent cremasteric reflex = torsion — image/operate now, don’t wait.
