Effect of Pentoxifylline and Zinc Co-administration in Patients With Oligoasthenoteratozoospermia (OAT)

Evaluating the Therapeutic Effect of Pentoxifylline and Zinc Co-administration in Patients With Idiopathic Oligoasthenoteratozoospermia

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 be performed as a double-blind randomized clinical trial on idiopathic infertile men (including oligoasthenosospermia, dyspnea, astheno-teratozoospermia, oligo-astheno-teratozoospermia) referred to Shafa Infertility Clinic. Patient satisfaction, non-use of contraceptives, men aged 25 to 43 years and idiopathic infertility according to WHO criteria (World Health, 2010) are our study criteria. A food questionnaire is also taken from them to identify patients. Any medication that may affect sperm production should be discontinued within three months of the study. Sampling and administration of pentoxifylline and zinc: Preparation and analysis of semen samples are performed according to WHO 2010 recommendations. Semen samples are prepared by masturbating after a 3 to 5 day abstinence period. Two semen samples from these men, one before and the other after the intervention, are evaluated for basic parameters. For liquefaction, semen samples are incubated for 30 to 60 minutes at 37 ° C. Microscopic tests are performed to evaluate indicators such as sperm concentration in semen, motility and sperm morphology. Objectives and study methods are explained to patients who meet the inclusion criteria. Written consent is then obtained from the candidate. Body mass index (BMI) is assessed for patients. Also, at the beginning of the study, 5 cc of blood is taken from patients to measure reproductive hormones.

Intervention group 1: received pentoxifylline (TRENTAL 400 mg modified release tablets, OSPS; 400 mg ,two times daily)

Intervention group 3: received pentoxifylline+ zinc (TRENTAL 400 mg modified release tablets, OSPS; 400 mg ,two times daily + Zinc Sulfate 220mg Capsules,One time daily )

Infertile men referred to the infertility treatment center who, have had at least one year of unprotected intercourse, Natural fertility has not happened in their spouse. These men will all be married These men will be between the ages of 20 and 50. According to WHO criteria, Sperm parameters abnormalities should be observed in at least two spermogram within 2 weeks. Candidates receive two placebo tablets daily
