Basic knowledge of human reproduction can help youth prepare for puberty and make later classes focused on advanced reproductive health topics manageable. With the intention of potentially informing the creation of learning materials, we conducted a needs assessment among children ages 7 to 12 in our suburban Chicago community to ascertain their current understanding of, and beliefs and misconceptions about, human reproduction, and to determine their needs for additional reproductive health education. We held qualitative focus group interviews with local children. Participants primarily reported learning about these topics from their parents prior to receiving school-based education in fifth grade. Their level of understanding was relatively low. They had little knowledge of internal sexual organs, expressed a range of beliefs about conception ranging from inaccurate to accurate but incomplete, and voiced concerns about transitioning into adolescence. This suggests a need for additional resources that provide comprehensible descriptions of reproductive health processes and mitigate puberty-related concerns.

Girgentana goats are an ancient breed with distinctive morphological, adaptive, and production traits, making this population an interesting model for studying the genetic architecture underlying these traits. These special features result from natural and human-mediated selection. In this study, we aimed to detect potential signatures of selection in the Girgentana genome by combining the following statistical methods: the integrated haplotype score (iHS), the standardised log-ratio of the integrated site-specific extended haplotype homozygosity test between pairs of populations (Rsb), the runs of homozygosity (ROH) islands and the population differentiation index (F).

One of the major advancements in fertilization (IVF) has been the development of culture media that enhance gamete maturation and sustain embryo development up to the blastocyst stage. The deep understanding of the mechanisms involved in gametogenesis and the complex sequence of events surrounding nuclear and cytoplasmic maturation has also enabled the development of efficient maturation (IVM) protocols. This review outlines the major landmarks in the history of maturation of oocytes, the advantages and importance of its clinical application in human, especially in patients with Polycystic Ovary Syndrome (PCOS), Resistant Ovary Syndrome, high antral follicle count or oncology patients, as well as the safety and efficacy of the technique.

Research Question: What are the trends and impact of new technologies on the effectiveness and safety of assisted reproductive technology (ART) performed in Latin America during 2021?
Design: This was a retrospective collection of cycle-based multinational data obtained from ART procedures performed by 204 accredited institutions in 16 countries.
Results: In total 127,351 initiated cycles resulted in 20,032 deliveries and 22,708 births. ART utilization showed great variability, from 623.

Expression quantitative trait loci (eQTLs) provide a key bridge between noncoding DNA sequence variants and organismal traits. The effects of eQTLs can differ among tissues, cell types, and cellular states, but these differences are obscured by gene expression measurements in bulk populations. We developed a one-pot approach to map eQTLs in by single-cell RNA sequencing (scRNA-seq) and applied it to over 100,000 single cells from three crosses.

Glyphosate-based herbicides (GBHs) are the most widely used herbicides in the United States, accounting for 19% of estimated global use. Although the Environmental Protection Agency (EPA) has reaffirmed that the active ingredient glyphosate (GLY) is safe for humans, recent studies on exposure have suggested association with cancer, metabolic disorders, endocrine disruption and infertility, Alzheimer's and Parkinson's disease, and psychological disorders. Current literature on the effects of GLY exposure on reproductive function suggests potential clinical implications on women's reproductive health, including polycystic ovarian syndrome (PCOS), endometriosis, infertility, and adverse pregnancy outcomes.
