On which side is a varicocele more common and why?
on the left because the left gonadal vein drains to the left renal vein before the IVC but it goes directly on the right
Which nodes do the testes/ovaries drain to?
para-aortic lymph nodes (retroperitoneal)
Where do the proxinal 2/3 of the vagina/uterus drain to?
obdurator, external iliac and hypogastric nodes
What does the cardinal ligament support?
cervix to side wall of pelvis
What vessels does the cardinal ligament contain?
uterine
Through which structure do the ovarian vessel pass?
suspensory ligament of the ovaries
Erection physio (pro- and anti-)
parasympathetic stim of pelvic nerve ==> inc. NO==> inc. cGMP ==> smooth muscle relaxation ==> vasodilation

tight junctions
support/nourish
regulate spermatogenesis
What is the function of the Leydig cells?
secrete testosterone
What is the progression of sperm maturation?
spermatogonium (2N diploid) ==> primary spermatocyte (4N) ==> secondary spermatocyte (2N, haploid)==>spermatid (N) ==> spermatazoa (N)
