Objective To assess the incidence of testicular atrophy by evaluation
of hormonal status, testicular histology and sperm production in chron
ic lepromatous patients. Patients and methods Forty-one male patients
with a mean age of 39.5 years (range 16-57) were studied at the Lepros
y Hospital, Istanbul, Turkey, and were compared with 15 age-matched co
ntrols with proven fertility. Results Reduced testicular size was obse
rved in 51% and gynaecomastia in 27%. Of the 31 patients who were marr
ied, 15 were primarily or secondarily infertile. Twelve of 16 patients
had oligospermia or azoospermia. The mean basal luteinizing hormone (
LH), follicle stimulating hormone (FSH) and oestradiol levels were sig
nificantly elevated and the level of testosterone significantly reduce
d when compared with the control group. Conclusion Whenever leprosy is
diagnosed patients should be informed of the need for treatment of an
acute attack and the need for routine assessment of FSH, LH, testoste
rone and oestradiol levels to detect hypogonadism and potential infert
ility.
