Does LH/Testo and Testo/LH ratio affect male fertility?

ABSTRACT

This study was designed to determine the levels of serum LH and Testosterone along with their ratios, among men with varying sperm quality. Two hundred fifty married men, presenting with a complaint of infertility, which had been evaluated for their seminal profile. LH indicated inverse/negative correlation to sperm concentration, while decreased testosterone levels were associated with depleted sperm conc. The mean levels of LH [mlU/ml] and testosterone [nmol/L] for the groups were 13.85 +/- 2.33 and 11.86 +/- 0.70 [azoospermia], 10.92 +/- 3.79 and 11.88 +/- 1.06 [oligozoospermia], 3.92 +/- 1.17 and 16.24 +/- 2.05 [asthenozoospermia], while the levels in normozoospermic men were 7.24 +/- 1.02 and 17.29 +/- 1.02, respect. Similarly, the LH/T and T/LH ratios were 1.17[ +/- 0.28] and 0.86[ +/- 2.70] respectively in azoospermia, 0.92 [ +/- 0.28] and 1.08[ +/- 0.17] in oligozoospermia, 0.30[ +/- 0.10] and 4.14[ +/- 10.4] in asthenozoospermia 0.42 [ +/- 0.08] and 2.34[ +/- 0.48] in normozoospermic men. The present data indicate that disturbance in LH and testosterone ratios also causes infertility, since these hormones act together by maintaining a feedback control system
