Filter by:Spermatozoa are vulnerable to lack of energy and oxidative stress as a result of elevated levels of reactive oxygen species. Therefore, it is essential that appropriate nutrients are available during maturation. This randomized, double-blind, placebo-controlled trial investigated the effect of 6 months supplementation with carnitines and other micronutrients on sperm quality in 104 subjects with oligo- and/or astheno- and/or teratozoospermia with or without varicocele. Semen analyses were done at the beginning and end of the treatment. In addition to main analyses, post-hoc analyses for age and body mass index (BMI) were carried out. Results were interpreted by dividing the population into two age and BMI classes.
In vitro sperm selection for ICSI is important as it has a direct influence on the paternal contribution of preimplantation embryogenesis. Various laboratory tests were developed to assess the functions of the spermatozoa. Among them, only the tests for sperm DNA fragmentation, hyperactivation of the spermatozoa and the hyaluronan-binding ability are simple and fast.
Microfluidic chips are one of the methods of sperm separation to eliminate DNA fragmentation in sperm. It is thought that the separation of sperm by centrifugation in the classical gradient density (Percoll) method used in sperm separation in IVF (in vitro fertilization) laboratories leads to the increase of reactive oxygen radicals in sperm and this leads to sperm DNA fragmentation. Studies comparing Percoll and microfluidic chip method in terms of sperm, embryo quality and pregnancy rates are limited. In this context, it is aimed to investigate the effect of Percoll or Microfluidic Chip Technology on the quality of sperms and embryos obtained with these sperms and their pregnancy rates prospectively.
The study was conducted to assess the impact of two doses of coenzyme Q10 on seminal fluid parameters and antioxidant status in infertile men.
The study was conducted to assess the impact of coenzyme Q10 and selenium on seminal fluid parameters and antioxidant status in infertile men.
The study is a drug trial comparing the post-operative pain control provided by liposomal bupivacaine (a local anesthetic) against standard bupivacaine (a different formulation of the local anesthetic) for men undergoing testicular sperm extraction.
Andrositol® test allows to obtain additional information besides the WHO parameters and to evaluate the semen energetic status. The diagnosis is performed by analyzing the semen at two different time points: before the treatment and 30' after the addiction of myo-inositol directly to the semen. The purpose of this study is to evaluate if the responsiveness to the Andrositol® test of a sperm sample can be predictive of its fertilization rate in an ICSI (Intracytoplasmic Sperm Injection) cycle (primary outcome). Secondary outcomes as embryo development, embryo euploidy status and embryo implantation rate will be evaluated.
Tobacco is a male infertility risk factor. Many studies comparing smokers to non-smokers have shown effects on spermatogenesis and the quality of the male gamete. In vitro fertilization success rates are decreased in smokers and in natural procreation the time required to conceive (excellent fertility indicator) seems to be lengthened in the smoker. The prospective study that the investigators propose to carry out would make it possible to know the time required for the repair of the sperm abnormalities and in particular the DNA of the gametes generated by the smoking.
Infertile men due to oligoasthenospermia with non-tense hydroceles are subjected to ICSI
Increased sperm DNA Fragmentation Index implies decreased male fertility in vivo and in vitro. There is need for developing new strategies for improvement of male fertility. The study aims to investigate whether high sperm DNA Integration Index can be treated by use of antioxidants.
