Male infertility and mitochondrial DNA

The mitochondrial machinery plays a key role in the energy production and maintenance of spermatozoa motility. In this paper 200 idiopathic oligo-asthenozoospermic patients were classified on the basis of rapid progressive motility ("a") and sperm concentration. Mitochondrial enzymatic activity was studied and correlated to the viability of sperm cells. Mitochondrial DNA purified from both motile and non-motile sperm of the same individuals was amplificated using PCR. Results suggested that only motile sperm have organelles functional in oxygen consumption, unequivocally demonstrating that motility depends on the mitochondrial activity. Mitochondrial DNA of oligo-asthenozoospermic patients …

Gonadotropic Therapy in Men with Hypogonadotropic Hypogonadism

Many therapeutic regimens, differing in dose and duration, have been employed in the treatment of hypogonadotropic hypogonadism. This study presents the results from a regimen of hCG plus hMG plus testosterone combined treatment in 15 patients affected by selective hypogonadotropic hypogonadism. The patients were homogeneous in age (16–23 years), testicular size, aspermia, absence of prior hormonal treatment, and normal karyotype. They were administered 5000 IU of hCG plus 75 IU of hMG twice a week for two months and a single dose of depo-testosterone (250 mg) in the third month. This therapeutic plan was carried out continuously for eight three-month cycles (24 months). Sexual maturation a…
