azoospermia/グルタチオン

OBJECTIVE To assess the association between glutathione-S-transferase gene polymorphisms GSTT1, GSTM1 and GSTP1 and onset of azoospermia. METHODS Multi-PCR was used to detect GSTM1 and GSTT1 gene deletions. Polymorphisms of GSTP1 were determined with restriction fragment length polymorphism (RFLP)

OBJECTIVE To investigate the association of glutathioneS-transferase T (GSTT1) gene polymorphism with azoospermia and oligospermia. METHODS Semen samples from 34 patients with idiopathic azoospermia, 40 patients with idiopathic oligospermia and 53 healthy controls with normal sperm concentration and

OBJECTIVE To investigate the association of glutathione S-transferase T1 (GSTT1) gene polymorphism in patients with idiopathic azoospermia or oligospermia in the northwestern China population. METHODS In the case-control study, GSTT1 genotypes were identified by multiplex polymerase chain reaction

The reported effects of the glutathione S-transferase (GSTs) genes (GSTM1, GSTT1, and GSTP1) on male factor infertility have been inconsistent and even contradictory. Here, we conducted a case-control study to investigate the association between functionally important polymorphisms in GST genes and

OBJECTIVE To investigate the status of seminal plasma reduced glutathione (GSH) and vitamin E in three different conditions of spermatogenesis: azoospermia, oligozoospermia and normospermia. METHODS Reduced glutathione was measured in the seminal plasma by the method of Moron et al (1979), and

Published data on the association between male infertility and the glutathione-S-transferase (GST) gene polymorphism are inclusive. To drive a more precise estimation, we performed a meta-analysis based on 1897 cases and 1785 controls from 15 published case-control studies. PubMed and CBMdisc

In most cases, exogenous oestradiol benzoate (EB) inhibits spermatogenesis, however, the mechanism underlying this process has not been fully elucidated. The present study investigated the effect of EB on redox equilibrium and glycometabolism in mouse testes. Male Kunming mice were divided into 3

Chemotherapy induced testicular toxicity is an emerging reason for azoospermia and impotency in males. Cyclophosphamide (CP) is a widely used chemotherapeutic agent to manage neoplastic and non-neoplastic autoimmune diseases. Testicular toxicity along with bladder and hepatotoxicity are its widely

Semen abnormality (SA) male infertility has become a worldwide reproductive health problem. The invasive tests (e.g., testicular biopsy) and labor-intensive methods of semen collection severely inhibit diagnosis of male infertility. In addition, the pathogenesis and biological interpretation of male

Genes of different pathways regulate spermatogenesis, and complexity of spermatogenic process indicates that polymorphisms or mutations in these genes could cause male infertility. Detoxification pathway is involved in the regulation of spermatogenesis by reducing oxidative stress and contributes to

Environmental xenobiotics such as organophosphate pesticides are known factors involved in male infertility. Paraoxanase (PON) and glutathione transferase (GST) are involved in biotransformation of organophosphate pesticides. Interindividual genetic variations in biotransformation enzyme activities

Glutathione-S-transferases (GSTs) play a protective role during spermatogenesis and GST genes may be involved in impaired spermatogenesis. A case-control study was performed to explore the association of genes GSTM1 and GSTT1, two members of GST gene family, with spermatogenesis impairment. The

Treatment with cyclophosphamide (CP), a commonly used anticancer and immunosuppressive agent, may result in oligospermia and azoospermia. CP administration induces oxidative stress and is cytotoxic to normal cells. In this context, we have studied the effect of an established antioxidant, lipoic

The present study was designed to explain the impact of amoxicillin, gentamicin, and cefazolin on the oxidative stress (OS) and reproductivity in the mouse testes. Our data showed that reduced glutathione (GSH) level, which is a marker for OS, strikingly reduced and hydrogen peroxide (H2O2) level,
