OBJECTIVE To investigate the relationship between testicular volume and semen parameter sin patients with unilateral high grade left varicocele. MATERIAL AND METHODS One hundred eighty seven patients who had left high grade varicocele aged 19-to-25 years were included in this study. All patients underwent a standard evaluation, including medical history and physical examination. The percentag...

Single intraperitoneal injection of lead acetate (200 mg/kg b.w) to Swiss mice stimulated testicular weight loss with a constant increase in the incidence of abnormal sperm population and decrease in the total sperm count. Testicular ascorbic acid also declined significantly during the post-treatment phase with significant rise in Lipid Peroxidation Potential (LPP) of the tissue. Elevated LPP i...

OBJECTIVE Determine whether testicular sperm extractions and pregnancy outcomes are influenced by male and female infertility diagnoses, location of surgical center and time to cryopreservation. PATIENTS One hundred and thirty men undergoing testicular sperm extraction and 76 couples undergoing 123 in vitro fertilization cycles with testicular sperm. OUTCOME MEASURES Successful sperm recove...

BACKGROUND The popularity of alpacas (Vicugna pacos) is increasing in Sweden as well as in other countries; however, knowledge about optimal management practices under Swedish conditions is still limited. The wide age range reported when the onset of puberty can occur, between 1 and 3 years of age, makes management decisions difficult and may be influenced by the conditions under which the alpa...

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...

Microdissection testicular sperm extraction (microTESE) is considered the gold standard method for surgical sperm retrieval among patients with non-obstructive azoospermia (NOA). In this review, we will discuss the optimal evaluation of NOA patients and strategies to medically optimize NOA patients prior to microTESE. In addition, we will also discuss technical principles and pearls to maximize...

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...
