title: Correlations between seminal radioimmunoreactive prolactin, sperm count, and sperm motility in prevasectomy and infertility clinic patients.
abstract: Semen samples were collected from 50 prevasectomy patients and 43 infertility clinic patients. Various parameters were measured, including semen radioimmunoreactive prolactin (rPRL) levels. Linear correlations were tested between the measured parameters, and a significant correlation was found between semen rPRL concentration and sperm count for both the prevasectomy (r = 0.73, P less than 0.00002) and the clinic patients (r = 0.72, P less than 0.00002). For the clinic patients a correlation was also found between the amount of ejaculate rPRL and sperm motility (r = 0.46, P less than 0.002) and between ejaculate volume and motility (r = 0.36, P less than 0.02).
