Objective: To assess the impact of Promescent, a commonly used topical medication for premature ejaculation (PE), on human sperm motility, forward progression (FP), viability, and sperm DNA fragmentation (SDF) in vitro.
Materials And Methods: Aliquots from specimens for diagnostic semen analyses from patients (n = 20) presenting to a couple's fertility center andrology laboratory for fertility testing were included after the full diagnostic semen analyses were performed. Samples that met the World Health Organization's fifth edition criteria as "normal" had Promescent applied to an aliquot of the sample and motility, FP, viability, and SDF were compared with an aliquot that was not treated with Promescent. Institutional review board exemption was obtained. Statistical analysis was performed by Student t test with a P value of <.05 considered as statistically significant.
Results: Promescent had a cytotoxic effect on sperm, which resulted in a statistically significant decrease in mean motility, FP, and viability as compared with corresponding control group samples, which did not have Promescent applied. There was no statistically significant difference in SDF between the 2 groups.
Conclusion: PE is estimated to affect up to 39% of men and is one of the most common self-reported male sexual disorders. There is an overlap among men with PE and those trying to achieve a pregnancy, and Promescent is a commonly used topical treatment for PE. Although there was no difference in SDF between the 2 groups, Promescent had a cytotoxic impact on sperm.

Infertility has emerged as a significant public health concern, with assisted reproductive technology (ART) is a last-resort treatment option. However, ART's efficacy is limited by significant financial cost and physical discomfort. The aim of this study is to build Machine learning (ML) decision-support models to predict the optimal range of embryo numbers to transfer, using data from infertile couples identified through literature reviews.

Background: Up to now, a number of studies have explored the influence of blastocyst biopsy on maternal and neonatal outcomes, and the results have been somewhat inconsistent. Therefore, the aim of this study was to investigate whether blastocyst biopsy is associated with an elevated risk of hypertensive disorders of pregnancy (HDP) and other adverse perinatal outcomes during frozen embryo transfer (FET) cycles in singleton live births resulting from intracytoplasmic sperm injection (ICSI) in women aged ≤ 35 years.
Methods: A total of 1,008 women were involved in this study from January 2020 to June 2022, who underwent ICSI cycles and received single FET, leading to the birth of a live singleton newborn.
The action of retinoic acid on spermatogonia in the testis.

For mammalian spermatogenesis to proceed normally, it is essential that the population of testicular progenitor cells, A undifferentiated spermatogonia (A), undergoes differentiation during the A to A1 transition that occurs at the onset of spermatogenesis. The commitment of the A population to differentiation and leaving a quiescent, stem-like state gives rise to all the spermatozoa produced across the lifespan of an individual, and ultimately determines male fertility. The action of all-trans retinoic acid (atRA) on the A population is the determining factor that induces this change.

Although considered an "eco-friendly" biodegradable plastic, polylactic acid (PLA) microplastic (PLA-MP) poses a growing concern for human health, yet its effects on male reproductive function remain underexplored. This study investigated the reproductive toxicity of PLA in male mice and its potential mechanisms. To this end, our in vivo and in vitro experiments demonstrated that after degradation in the digestive system, a significant number of PLA-MP-derived nanoparticles could penetrate the blood-testis barrier (BTB) and localize within the spermatogenic microenvironment.

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.
