Background: Diabetes-induced oxidative stress can have adverse effects on sperm and its DNA integrity. The Ashrasi date palm (ADP) has potent antioxidant properties. The aim of this study was to evaluate the antioxidant effect of ADP hydroalcoholic extract on sperm parameters and sperm DNA fragmentation in diabetic rats.
Methods: Forty male rats were randomly divided into five groups (n = 7): 1, control; 2, diabetic; 3-5, diabetic + ADP (30, 90 and 270 mg/kg for groups 3, 4 and 5, respectively). After preparation of ADP extract and its phytochemical screening, it was administered orally to rats, once a day for 5 weeks. At the end of the study, sperm parameters and sperm DNA fragmentation in all groups were investigated.
Results: At doses of 90 and 270 mg/kg, ADP extract significantly increased the sperm viability compared to diabetic group 2 (p = 0.04 and p = 0.03, respectively) and resulted in a significant decrease in immotile sperm (p = 0.002 and p = 0.006, respectively). At a dose of 270 mg/kg, a considerable enhancement of forward sperm motility was observed (p = 0.04) and there was a significant decrease in sperm DNA fragmentation (p = 0.04).
Conclusions: The findings of the present study show for the first time that the hydroalcoholic extract of ADP has protective and antioxidant effects against diabetes-induced oxidative stress and can improve sperm parameters and protect sperm DNA integrity.

It is believed that aneuploid embryos release cell-free DNA (cfDNA) into the blastocyst cavity during the self-correction process through the apoptotic mechanism. This study aimed to develop less invasive methods for predicting ploidy status by investigating how ploidy status affects blastocoel fluid DNA (BF-DNA) levels and apoptotic gene expression as indicators of embryo viability. Human blastocysts were classified into three groups; Survivable Embryo (SE), Fatal Single and double Aneuploidy (FSDA), and Multiple Aneuploidy (MA) using array comparative genomic hybridization (array-CGH) by trophectoderm (TE) biopsy.

Gene conversions are thought to occur within relatively short tracts of DNA, estimated to be in the order of 100-1,000 bp in humans. However, the number of observable gene conversion tracts per study has so far been limited by the use of pedigree or sperm-typing data to detect gene conversion events.

Background: In infertility clinics, long-time preserving high-quality spermatozoa is a challenging problem.
Objective: The present study aimed to prolong preserving of the human spermatozoa by adding pentoxifylline (PT) and L-carnitine (LC) without using high-cost freezing techniques.
Materials And Methods: In this experimental study, semen samples of 26 normozoospermia men aged between 28-34 yr, were firstly prepared using the swim-up technique, and each sample was divided into the following 3 aliquots: untreated control group, the LC, and PT-treated groups.

Estrogen through its receptors, ERα and ERβ, regulate various aspects of spermatogenesis and male fertility. Since the sperm epigenome is an important contributing factor to male fertility, we evaluated the effects of estrogen signaling activation through the ERs on sperm DNA methylome in adult rats. Whole genome-bisulfite sequencing (WGBS) in caudal sperm DNA was performed.
