Filter by:The object of study for patients with idiopathic disease of OAT, the use of multicenter, randomized, double-blind, controlled, prospective clinical research, choose according to row, standard units of idiopathic male infertility clinics less weak abnormal sperm, randomly divided into experimental group and the placebo group, the comparison between the two groups of patients and semen parameters before and after medication, seminal plasma hormone, serum lipid levels and other indicators;At the same time, serum and seminal plasma samples of the two groups of patients before and after treatment were collected for bioinformatics analysis of protein spectrum to find the effector molecules of Gulingji capsule.
Objective of the study is to compare the efficacy of tamoxifen alone & tamoxifen with antioxidant on semen quality of infertile male with abnormal parameters (sperm count, motility, vitality, morphology) .Infertility is defines as inability to conceive after one year of unprotected and regular intercourse. Infertility is the most important issue in the married couples and is one of the major clinical problem affecting people medically and psychologically .It affects about 5.8 to 44.2 % couples in the developing countries. Male infertility contributes to about 50% of the overall infertility. Antiestrogens are considered as one of the old and most commonly prescribed treatment of idiopathic infertility.Many studies has shown that it improves idiopathic oligozoospermia, count, motility and vitality. Spermatozoa are also prone to oxidative damage. Men who have high reactive oxygen species(ROS) may have lower fertility potential as compared to men with low ROS. High levels of ROS in semen have been correlated with reduced sperm motility and damage to sperm nuclear DNA. High levels of cytokines in the semen is correlated with sperm injury like cell membrane lipid peroxidation in the presence of raised IL-6 .Antioxidents are the most important form of protection for spermatozoa against ROS. So oral antioxidents are commonly prescribed to males with idiopathic abnormal semen parameters and infertility to reduce the oxidative stress and improves infertility. It is a single blinded randomized control trial to be conducted in Sharif Medical and Dental college, Lahore with sampling technique of probability randomized consecutive sampling technique. 110 male patients with idiopathic male infertility and abnormal semen parameters will be recruited . Pre treatment semen analysis and LH, FSH and serum testosterone will be done. 55 patients will be given tamoxifen alone ad 55 patients will be given tamoxifen with antioxidant. Then at the interval of 3 and 6 months after treatment , semen analysis and hormonal profile will be repeated. Pre-treatment and post treatment semen parameters will be compared using paired sample t-test. P-value < 0.05 will be taken as significant.
This trial will study the safety and efficacy of intravenous infusion of cultured allogeneic adult umbilical cord derived mesenchymal stem cells for the treatment of Testicular Injury and Oligospermia
The aim of this study is to investigate the impact of co-administration of Pentoxifylline and Zinc sulfate on oxidative stress, apoptosis, and inflammation, sperm capacitation and parameters in infertile men.
This study will evaluate the safety and feasibility of the ADAM System for implantation into the vas deferens in 60 healthy males at 3 sites. This is a prospective, non-randomized, open label interventional trial.
This study investigates the effect of repetitive cycles of a Fasting Mimicking Diet (3x5 days in six months) on sperm quality in men
In patients with oligospermia in the ejaculate or previous ICSI failures if it concurs with high DNA fragmentation, it has been hypothesized that the use of sperm obtained from the testicle would improve the clinical results, since a source of damage to the spermatic DNA is post-testicular in its storage in the epididymis and thus could be avoided. The clinical information available so far is low, of low quality and all the studies present certain limitations susceptible to improvements in further investigations before giving a definitive answer to patients in these circumstances, about whether they should opt for testicular biopsy or for the use of semen in the ejaculate.The intention proposed in our project, is to demonstrate whether using testicular sperm, compared to those available in an ejaculate in these cases, offers a clinically and statistically significant increase in chromosomally normal embryos available that may lead to better reproductive performance of the cycles, in a design never before done, where half of a patient's oocytes are inseminated from ejaculated sperm and the other half from sperm obtained in the testicular biopsy.
Coronavirus Disease-19 (COVID-19) is a global pandemics which affects many organs and systems with a range of morbidities and high mortality rates. There are a number of studies revealed that COVID-19 may affect the testes and male genital tract which may in turn disrupt the gonadal functions.The current study aimed to evaluate the effect of COVID-19 on semen parameters and sex-related hormone levels.
Cancer is a public health problem. In recent years, oncology has been revolutionized with the advent of new treatments for different tumor models, mainly immunotherapy directed against cell cycle control points. Numerous inhibitory pathways are incorporated into the immune system to maintain tolerance and homeostasis, and these are collectively known as immunological checkpoints. The main function of immunological checkpoints is to protect tissues from damage when the immune system is responding to pathogens and maintain tolerance to self antigens (ie, prevent autoimmunity). This is mainly achieved by down-regulation of T cell activation or effector functions. There is increasing evidence to show that a primary mechanism by which tumors evade the immune system is through the participation of immunological checkpoints. This has stimulated the development of many novel agents that modulate immunological checkpoints or other costimulatory receptors. CTLA-4 is the first receptor of the checkpoint that is successfully selected as immunotherapy. Ipilimumab, an anti-CTLA-4 monoclonal antibody, was the first immunological checkpoint inhibitor to receive FDA approval for the treatment of advanced melanoma. On the other hand, PD-1 is another receptor for the immune control point, and its ligands, the programmed cell death ligand 1 (PD-L1) and PD-L2, also resulted in important therapeutic advances in cancer immunotherapy. Unlike CTLA-4, PD-1 is widely expressed and can be found in, in addition to T cells, in B cells and natural killer (NK) cells. The main function of PD-1 is to limit the activity of T cells in peripheral tissues during an inflammatory immune response. The tumors can exploit this control point, expressing the ligand PD-L1 and generating that the cytotoxic T lymphocytes and the NK cells are anergic and incapable of killing. This up-regulation mechanism of PD-L1 is known in tumors such as melanoma, lung and ovary. Several monoclonal antibodies directed to PD-1 have already received approvals for their clinical use as Nivolumab and Pembrolizumab.
This is a cohort study including all the first seminal exams performed at the Fertility Center, Humanitas Research Hospital (Rozzano, Milan) between January 1998 and December 2018.
