FSH, LH, E2, progesterone, and testosterone in peripheral blood, spermatic vein, and semen of subfertile men with varicocele.
Peripheral blood (PB), spermatic vein (Sp. V.), and semen samples were collected from 31 subfertile men with varicocele. Levels of FSH, LH, estradiol, progesterone, and testosterone were determined in the three biological fluid compartments using RIA. Remarkable increases in both testosterone and estradiol in the spermatic vein samples, as compared to either peripheral blood or semen, were evident. Correlation coefficient indicated significant positive correlation between PB FSH and each of PB LH, Sp. V. FSH, and Sp. V. LH. Significant positive correlation existed between PB LH and each of Sp. V. FSH, LH, and testosterone. Significant positive correlations were found between PB testosterone and each of Sp. V. testosterone and semen testosterone, as well as between PB estradiol and each of Sp. V. FSH and progesterone. Significant positive correlations between Sp. V. FSH and Sp. V. testicular progesterone was significantly correlated with seminal estradiol.
