FSH and Semen Analysis

What We Do

“Big 6”: morning testosterone, LH, FSH, SHBG, albumin, estradiol Prolactin if symptoms (visual field defects, headaches, ED, etc.)If testosterone is borderline, morning testosterone & LH x 3, 30 minutes apart for average

Pathophysiology of Aging

Diminished testicular response to gonadotropins (! Leydig cell production)Attenuation of gonadotropins in response !to decreased androgen level (! LH)Altered function (pulsatility) of GnRH pulse generator

“Using the results of two semen analyses did not lead to a better goodness-of-fit. Discriminative capacity was rather poor, with an area under the ROC curve (AUC) ranging from 0.51 to 0.56.”

“Accepting <30% normal forms as the threshold for WHO 3rd criteria, 31 (25.8%) of 120 patients were teratozoospermic in era 1 compared with 85 (77.3%) of 110 patients in era 2. Similarly, with a strict criteria threshold of % 4% normal forms, 24 (31.6%) of 76 patients were teratozoospermic in era 1 compared with 75 (56.4%) of 133 patients in era 2.”
