Filter by:Purpose: To compare the effects of the density gradient centrifugation and microfluidic chip sperm preparation methods on embryo development in a study population with astheno-teratozoospermia. Materials and Methods: In this prospective study, the semen samples of the patients with astheno-teratozoospermia were divided into two groups for preparation with either the microfluidic or density gradient methods. Selected spermatozoa were used to fertilize the mature sibling oocytes. Semen parameters and embryo development on days 3 and 5 were assessed.
Mitochondria is the cellular organelle responsible for the production of the energy necessary to fuel sperm motility. It has been demonstrated that mitochondrial efficiency is correlated to the fertilizing capacity of the spermatozoon and to the production of high quality embryos. Mitochondria efficiency is measured in the laboratory setting by evaluating the mitochondrial membrane potential. Myo-inositol is the most represented stereoisomer of the family of inositols and is the only one physiologically concentrated within the seminal plasma. It is essential for sperm maturation and motility and its deficiency is also associated to a reduced sperm count. Myo-inositol promotes motility and allows recovering a higher number of sperm cells after swim-up, both in normospermic patients and in patients with altered seminal parameters. Scientific studies have shown that semen samples treated in vitro with ANDROSITOL®DGN, show an improvement in mitochondrial efficiency that results in an increase in spermatozoa progressive motility. Based on the percentage increase in the progressive motility showed by the spermatozoa after incubation with ANDROSITOL®DGN (ANDROSITOL®TEST), it is possible to subdivide the semen samples into three categories: low, medium, and high responders. The aim of the study is to evaluate whether the in vitro response of spermatozoa to ANDROSITOL®TEST correlates with the in vivo improvement of seminal parameters after oral treatment with antioxidants and myo-inositol.
The present Pocock clinical trial study was conducted In the city of Mashhad in Iran between 2015 and 2016. The study inclusion criteria were men with low fertility of sperm motility<25% and total motility <50% (asthenozoospermia), no history of endocrine diseases, no diabetes men, no hormonal problems in their wives, and a healthy salpingography in their wives. The study subjects were voluntarily assigned to royal gel and IUI groups. In royal gel group, 5 grams of royal gel was used after menstruation and every other night before and after intercourse. IUI group received 75 units of FSH from the second day of the cycle. Then vaginal ultrasound was performed from the sixth day of menstrual cycle to determine the right size of follicle. 10000 units of HCG was administered when follicle diameter reached 16mm, and the study subject was prepared for IUI 32-36 hours later. Each subject alternately swapped groups following fertility failure.
Although several studies have considered the relationship between infertility and semen thiol compounds levels, no study on the effects of asthenospermia treatments such as oral zinc supplementation on thiol related enzymes activity which are important in fertility of the individual has been reported.
Although several studies have considered the relationship between infertility and semen super oxide radical scavengers levels, no study on the effects of asthenospermia treatments such as oral zinc supplementation on superoxide radical scavengers activity which are important in fertility of the individual has been reported.
The investigators are testing the hypothesis that two ounces of whole-shelled walnuts/day added to the diet of men seeking care for infertility will beneficially affect sperm parameters and fertility. The investigators will compare the walnut intervention to the commonly suggested recommendation of adding an OTC multivitamin supplement to the diet.
Since docosahexaenoic acid (DHA) level in sperm membrane has been shown to be decreased in asthenozoospermic men, the investigators hypothesized that DHA supplementation may improve it. Furthermore, the investigators added vitamin E to it to protect its unsaturated bonds which are susceptible to oxidation and production of free oxygen radicals.
Many clinical evidences suggest that Myo-inositol plays a crucial role in human reproduction. Also, it was shown that Myo-inositol concentration in the seminiferous tubules was higher than in serum, and interestingly it was increasing through the epididymis and the deferent duct mining that sperm cell before ejaculation are stored in a "medium" highly enriched in myo-inositol. Starting from this evidences, the investigators hypothesized that myo-inositol may be a possible factor able to improve the semen parameters of samples used in in vitro fertilization cycles.
The ability of spermatozoa to produce reactive oxygen species (ROS) has been respected since the 1940's. Oxidative stress limits the functional competence of mammalian spermatozoa via lipid peroxidation, the induction of oxidative DNA damage and the formation of protein adducts. Nitric oxide (NO) is a free radical generated from the oxidation of L-arginine to L-citrulline by reduced nicotinamide adenine dinucleotide phosphate (NADPH)-dependent NO synthases. Several studies suggest that the overproduction of this free radical and the subsequent excessive exposure to oxidative conditions have a potential pathogenetic implication, which due to the reduction of sperm motility. The present study was conducted to study the effect of Zn supplementation on the levels of NO synthase and arginase in semen of patients with asthenozoospmia.
There are several causes leading to male infertility, like oxidative stress, and nutritional deficiency of trace elements like zinc. Zinc in human seminal plasma was divided into three types of ligands which are high (HMW), intermediate (IMW), and low molecular weight ligands (LMW). The present study was conducted to study the effect of Zn supplementation on the quantitative and qualitative characteristics of semen along with Zinc Binding Protein levels in semen of patients with asthenozoospmia.
