Background: Single sperm cryopreservation (SSC) is a method that preserves the limited number of spermatozoa in testicular sperm. But testicular spermatozoa are characterized with low movement, which is not ideal for sperm selection before SSC.

Objective: This study was designed to investigate in vitro incubation (IVC) as a sperm selection technique before SSC on biological factors of testicular spermatozoa.

Introduction: In end stage renal disease )ESRD(, reduced EPO production resulted in decreased oxygen diffusion that cause Hypoxia-inducible factors (HIFs) stabilization. The mechanism of beneficial effects of HS in chronic kidney disease (CKD) is the aim of the present study to examine the effects of the HS donor sodium hydrosulfide (NaHS) on renal function parameters, oxidative stress indices and expression levels of HIF-2α gene and erythropoietin protein in 5/6 nephrectomy-induced chronic renal failure in rats.

Methods And Materials: Male rats were assigned into 3 groups (n = 8): Sham, CKD and NaHS groups.

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that can cause infertility. This experimental study was conducted to elucidate the role of adiponectin signaling in rats with PCOS treated with exenatide. Twenty-eight adult female Wistar rats were divided into four groups of seven.

Background: Single sperm cryopreservation (SSC) is a specific technique especially used in individuals with small numbers of sperm who suffered from non-obstructive azoospermia (NOA). Testicular specimens possess poor motility and low population of viable spermatozoa. Therefore, sperm selection methods such as applying pentoxifylline (PTX) may improve motility in these cases.

Purpose: Platelet-rich plasma (PRP) is enriched with active biological components which showed proliferative and cytoprotective properties in healing different injuries in medicinal fields. This study was designed to assess the cryoprotective effects of autologous PRP on the quality of oligoasthenoteratospermia (OAT) samples during freezing and thawing procedure.

Materials And Methods: The present study is an experimental research.
