Plasma testosterone, luteinizing hormone and follicle-stimulating hormone one day after vasectomy.

ABSTRACT

PIP: In the attempt to clarify the stress effect of vasectomy, the plasma testosterone -- luteinizing hormone (LH) and follicle stimulating hormone (FSH) was measured before and 1 day following bilateral transcrotal vasectomy performed on 20 men between the ages of 24 and 53 years. Plasma testosterone -- LH and FSH -- were measured by radioimmunoassay. All measurements were performed in duplicate and samples from each individual were measured in the same assay. All values were in the normal range, and there was no signficant change after surgery (compared to basal values) in any of the parameters measured. The data suggest that the decrease in free testosterone index and FSH reported by others at 1-week post-vasectomy is probably not related to the effects of psychological stress, local anesthesia or surgical stress, either singularly or in combination.
