Thirty cases with androgenetic alopecia and ten healthy controls (male to female ratio was 1:1) were subjected to the measurement of serum hormonal levels (total testosterone, free testosterone, dehydro- epiandrosterone sulphate, estradiol, progesterone and prolactin). All hormones were analysed by radioimmunoassay technique. The evaluation of our hormonal findings revealed that there was a statistically significant increase in serum estradiol levels in male cases than controls while the other hormones showed that there was no statistically significant difference between both groups.
