Chlamydia trachomatis infection in male partners of infertile couples: incidence and sperm function.

abstract：:To further investigate the effectiveness of pentoxifylline (trental) treatment in male infertility, we studied 22 young men (mean age 28.4 years) with "idiopathic" oligo-asthenozoospermia treated for 6 months with the drug (1200 mg daily orally). Sperm concentration and sperm motility were determined before therapy, a...
