Microfluidic devices employing chemo- and thermotaxis for sperm selection can improve sperm parameters and function in patients with high DNA fragmentation.

Conventional sperm processing uses centrifugation has a negative effect on sperm parameters and DNA integrity. We designed and fabricated a novel microfluid device based on chemotaxis and thermotaxis, and compared it with the swim-up method. Twenty normal samples with high DNA fragmentation were included.

Effect of Coronavirus Disease (COVID-19) on Human Semen: No Evidence of Coronavirus in Semen of Patients.

Background: In December 2019, a severe acute respiratory syndrome (SARS-COV-2) was found in China. The coronavirus can impact different organs, as shown by the virus having been detected in urine, blood, oropharyngeal, and feces. This study was done to assess the impact of COVID-19 on semen analysis and to evaluate the existence of the virus in the semen of infected men.

Success rate and ART outcome of microsurgical sperm extraction in non obstructive azoospermia: A retrospective study.

Background: The management of non-obstructive azoospermia (NOA) disease relies on microdissection testicular sperm extraction (micro-TESE). Few studies have assessed the role of micro-TESE in men with NOA in our country.

Objective: The aim of the current study was to investigate the success rate of micro-TESE.

The relationship between major dietary patterns and fertility status in iranian men: a case-control study.

In this case-control study, we aimed to investigate the association between major dietary patterns and fertility status in Iranian men. The study population included 400 newly diagnosed infertile men and 537 healthy individuals without a history of infertility in Yazd, Iran. Infertility was confirmed clinically, based on the World Health Organization (WHO) criteria.

Does resveratrol affect prepared sperm parameters and chromatin quality in normozoospermic and asthenozoospermic patients before and after freezing? A lab trial study.

Background: Previous studies have examined the effect of resveratrol as a potent antioxidant for free radicals in semen. While, the prepared spermatozoa are more affected by ROS factors due to centrifugation and incubation.

Objective: To evaluate the RSV's effects on the prepared sperm parameters and chromatin quality in both normozoospermic and asthenozoospermic cases before and after freezing.
