A nomogram of the neonatal peak of urinary follicle stimulating hormone,luteinizing hormone and testosterone in normal male infants

Daily urinary follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone (T) levels were estimated in a group of 10 normal one month old male infants. Four-hourly urine samples were collected from each infant over a three months period i.e., from one month to four months of infants age. The hormonal levels were expressed as mIU of FSH, LH and ng of T per mg creatinine. The normal hormonal pattern thus obtained could be used to compare patterns obtained from pathological cases or when monitoring the effects of drugs on infants.
