title: Fructose and hormone levels in semen: their correlations with sperm counts and motility.
abstract: Levels of fructose, growth hormone (GH), prolactin (HPr), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and 5alpha-dihydrotestosterone (DHT) were determined in semen. The samples were obtained from patients attending an infertility clinic and separated into four groups according to the number of spermatozoa. Levels of HPr, LH, and FSH showed significant positive correlations with sperm counts. Significant differences in fructose and hormone levels were found between various groups. Expressed as concentrations of hormones or fructose per milliliter of semen, none of the hormones showed a significant negative correlation with sperm motility whereas fructose showed a significant negative correlation. Expressed as amounts per ejaculate of semen, only prolactin showed a significant positive correlation with sperm motility. The significance of these findings is discussed.
