[Clomiphene citrate therapy in idiopathic male infertility].

Clomiphene citrate therapy was performed on 30 patients with idiopathic male infertility, who were intractable to non-hormonal therapy. Clomiphene citrate was administered orally at a dose of 25 mg per day for 25 days with 5 days of rest following Paulson' protocol, and we favorable results were obtained: Both sperm count and sperm motility improved in 11 cases (36.7%). Odera's score count decreased in 14 cases (46.7%), which were judged as effective. The wives of 4 patients treated by this therapy became pregnant. After this therapy, the serum levels of luteinizing hormone, follicle stimulating hormone, testosterone and prolactin were 1.90, 1.81, 1.89 and 1.22 times higher, respectively. These findings indicate that clomiphene citrate therapy is an effective for idiopathic male infertility, but we need to consider that the sudden and marked elevation of serum testosterone level by this therapy might affect male accessory sex organs such as the prostatic gland which shows androgen dependency later in life.
