The effect of clomiphene citrate on pubertal gynaecomastia.

Clomiphene citrate 100 mg daily was used to treat 28 boys with pubertal gynaecomastia. Six failed to complete the course and of the remaining, 14 (64%) responded within 6 months of commencement of therapy. LH, FSH, testosterone and oestradiol levels rose during therapy. It is suggested that clomiphene affects gynaecomastia locally as an anti-oestrogen.
