Document Summary
Circumcision: surgical removal of foreskin, started in egypt, big rite of passage in jews, commemorate mark w/ abraham. America = what happened to dad"s penis = son. Cryptorchidism: undescended testicle, originally in abdomen, travels up and down throughout childhood and finally settled in scrotum. Emission phase: fluid emitted internally, building up: prostate, seminal vesicles, upper parts of vas deferens forcing secretions into ejaculatory ducts + urethra, urethral sphincters close, trapping seminal fluid in urethral bulb, ejaculatory inevitability = point of no return. Retrograde ejaculation: sphincters work in reverse function, side effects of plavix. Testicular cancer: 20-34 y/o, monthly self-exam, fam history. Prostate problems: enlargement constricts urethra; prostatitis: prostate cancer: 1/8 men, slow growing, surgery = 75% chance of ending sexual function, more common in blacks than whites. Peyronie"s disease: excessive curvature due to buildup of fibrous tissue in shaft = calcification, no treatment. Testicular torsion: flipped testis, tangles spermatic cord = lack of blood supply, dead testicles.
