Effect of statin on semen quality characteristics.

abstract：:In 20 autoptically obtained testes from men of various ages, 250-290 testicular lobules per testicle could be recognized by preparation with a stereomicroscope. The most appropriate technique was the fixation of the testes in 10% formol for at least 14 days and a following dehydration in a series of increasing concent...
