The existence of sterile neutrino is hinted by simultaneous explanation of diverse neutrino anomalies. We suggest that the quasi Goldstone fermions (QGF) arising in supersymmetric theory as a result of spontaneous breaking of global symmetry like the Peccei-Quinn symmetry or the lepton number symmetry can play a role of the sterile neutrino. The smallness of mass of QGF (mS ∼ 10 − 10 eV) can be...

This study aims to determine the relative contribution of oocyte and/or sperm dysfunction to the reduction of fertilization rates in vitro in cases of minor endometriosis and prolonged unexplained infertility. The results of in-vitro fertilization (IVF) treatment with ovarian stimulation have been compared between couples with the above conditions and women with tubal infertility (as control fo...

The presence of various cytokines, namely the tumor necrosis factor (TNF-alpha), interferon (IFN-gamma), and interleukins (IL-1 beta and IL-6), was investigated in seminal plasma of fertile, infertile, and immunoinfertile men using specific immunoradiometric assays. TNF-alpha and IL-1 beta were not detected. IFN-gamma was detected, but the differences between the levels of fertile and infertile...

Infertility can lead to shame, stigma, anxiety, depression, low feelings of self-esteem and guilt. According Times India 27.5 million Couples in suffering from infertility. WHO estimates the overall prevalence primary be between 3.9 16.8 percent [1]. due women (33%), man (33%) by both sexes or unknown problems approximately. varied reasons most times these cause are treatable. Assisted reproduc...

OBJECTIVE To evaluate ejaculated spermatozoa from patients with male factor infertility for the role of cytochrome c and caspases 9 and 3 (the proteins known to mediate apoptosis) and to examine association between semen quality and apoptosis in the presence of oxidative stress. DESIGN Prospective study. SETTING Male infertility clinic at a tertiary health care center. PATIENT(S) Semen sp...

introduction: prevalence of infertility in general population is around 15-10 percent. intra- uterine insemination (iui) is one method for treatment of infertility. success rate of this method is affected by different factors. past studies have shown that induction of ovulation and iui has increased significantly the chance of pregnancy in the infertile couple, especially male factor infertilit...

Unexplained infertility is a diagnosis reserved for couples in whom routine semen analysis is within normal values and female infertility factors have been ruled out. Its reported prevalence ranges from 6–27 % depending on how exhaustive the patient work-up is. Despite differing according to urological societies, recommendation for male infertility evaluation usually considers routine semen ana...

Background: Infertility is defined as the failure to conceive after 1 year of unprotected sexual intercourse in women less than 35 years age and 6 months older [1, 2]. It affects 10 15 % couples [1]. Abnormalities fallopian tubes account for 40 cases infertility [3]. Sonosalpingography a non-invasive, safe cost- effective diagnostic technique which provides reliable diagnosis tubal patency [4]....

About 15% of heterosexual couples in the USA suffer from infertility issues; male infertility accounts for ∼50% of all infertility cases and roughly 50% of male infertility is idiopathic. Increased levels of plasma cholesterol affect spermatogenesis and male fertility negatively, but by unclear mechanisms. Clearly, spermatogenesis occurs in immune-privileged seminiferous tubules that are protec...

The present review aims to ascertain whether different infertility etiologies share particular genes and/or molecular pathways with other pathologies and are associated with distinct and particular risks of later-life morbidity and mortality. In order to reach this aim, we use two different sources of information: (1) a public web server named DiseaseConnect ( http://disease-connect.org ) focus...
