title: Pulse pattern of luteinizing hormone (LH) in patients with varicocele: a preliminary report.
abstract: Serum concentrations of LH were measured every 20 minutes for 6 hours in 4 varicocele patients and 4 control subjects. In both groups, a pulsatile pattern of LH secretion was observed. Also in the two groups, LH pulse rate (2-5/6 hour) and amplitude (23.5-61%) were identical. These findings suggest that Gonadotrophin releasing hormone (Gn RH) and LH secretions have no role in the deranged sperm parameters often found in infertile men with varicocele.
