BACKGROUND This study was carried out to evaluate whether bilateral orchidopexy represents a poor or good prognostic factor in azoospermic men undergoing testicular sperm extraction (TESE). METHODS One hundred and seven presumed non-obstructive azoospermia (NOA) patients, according to conventional clinical parameters (volume of testis, FSH, clinical history) were submitted to testicular biops...

The purpose of this study was to determine the relationships between monitors of spermatogenesis and predictors of the intracytoplasmic sperm injection (ICSI) outcome in patients with non-obstructive azoospermia (NOA) undergoing testicular sperm extraction (TESE). Seventy-nine patients with NOA (mean age: 43.6±5.2 years), each of whom yielded (97 000±3040) spermatozoa with conventional TESE, we...

Submit Manuscript | http://medcraveonline.com reduced [3]. The reduction in fertility is documented in patients following orchidectomy with a contralateral viable testicle. In this case the contralateral testicle was atrophic following previous misdiagnosed torsion. Patients with severe testicular atrophy have undergone successful microdissection of sperm, in one study up to 56% of patients wit...

We report two cases of infertility treatment in couples where males suffered from Kartagener's syndrome (KS) and a total absence of motile sperm in the ejaculate. A total of three ICSI cycles was carried out. In all cycles, viable ejaculated or testicular spermatozoa were selected using the hypo-osmotic swelling (HOS) test. Case 1: In the first ICSI cycle total fertilization failure occurred af...

The effects of hypercholesterolaemia on testicular endocrine and exocrine function were evaluated. The influence of hypercholesterolaemia on sperm quality, quantity, and fertilizing potential was also determined. Ten mature rabbits (group A) were fed chow containing 3% cholesterol for 12 weeks. Ten control rabbits (group B) were fed normal chow for the same period. At the end of the experimenta...

Background. Reduced testicular volume (TV) (<12 cm(3)) is associated with lower testicular function. Several studies explored the conventional sperm parameters (concentration, motility, and morphology) and the endocrine function (gonadotropins and testosterone serum concentrations) in the patients with reduction of TV. No other parameters have been examined. Aim. This study aims at evaluating s...

background: pentoxifylline (px) is a methyxanthin derivative that influences the sperm motion characteristics. in general, px has been reportedly effective in preserving sperm motility in vitro, also when administered orally to the asthenozoospermic patients. objective: the main objective of this prospective clinical trial study was to rule out the effect of oral administration of px on sperm p...
