Evaluating the therapeutic effect and toxicity of theophylline in infertile men with asthenoteratozoospermia: a double-blind, randomized clinical trial study.

Theophylline as a cyclic adenosine monophosphate (cAMP) phosphodiesterase inhibitor (cAMP-PDEI) elevates cAMP levels. We aimed to evaluate the therapeutic effect and toxicity of theophylline on the sperm parameters, oxidative stress (OS), and inflammation in asthenoteratozoospermic men. Sixty asthenoteratozoospermic patients were divided into groups of placebo and theophylline (200 mg/day).

Association of Herpes simplex virus I&II infections with rs187084 SNP of TLR9 and male infertility.

Since TLR9 recognises unmethylated CpG motifs in viral DNA, its polymorphisms may contribute to the susceptibility to Herpes simplex virus I&II infection. In the present study, to evaluate the role of rs187084 SNP (single nucleotide polymorphism) of TLR9 in Herpes simplex virus I&II infection and male infertility, 103 infertile and 27 fertile blood and semen samples were analysed. We assessed the micro and macro properties of semen specimens and the presence of HSV immunoglobulins.

Ameliorative effect of melatonin on apoptosis, DNA fragmentation, membrane integrity and lipid peroxidation of spermatozoa in the idiopathic asthenoteratospermic men: In vitro.

Fertility loss, recurrent spontaneous abortion and poor outcome in assisted reproductive techniques (ART) have been associated with DNA fragmentation. This work was achieved to evaluate the protective role of melatonin versus apoptosis, DNA fragmentation, membrane integrity and lipid peroxidation of spermatozoa from men with asthenoteratozoospermia (ATS). Some researchers maintain that melatonin can serve as a remedy for apoptosis induction, and it has an impressive effect on boosting the quality and quantity of spermatozoa.

Protective effect of L-carnitine on apoptosis, DNA fragmentation, membrane integrity and Lipid peroxidation of spermatozoa in the asthenoteratospermic men.

This in vitro study aimed to measure the ameliorative effect of L-carnitine against apoptosis, DNA fragmentation, membrane integrity and lipid peroxidation of spermatozoa from men with asthenoteratozoospermia (ATS). L-carnitine has an impressive effect on boosting the quality and quantity of spermatozoa and also can prevent apoptosis induction. For this purpose, semen samples were collected from 50 ATS men.

The effect of vitamin E on sperm motility and viability in asthenoteratozoospermic men: In vitro study.

Induction of oxidative stress during the sperm preparation process for assisted reproductive techniques (ART) in men can weaken sperm parameters. Vitamin E (VE) is considered a factor in boosting male fertility. This experimental study (in vitro) aimed to assess the impact of VE supplementation on sperm quality and lipid peroxidation during sperm sampling at different times.
