Seminal Plasma Exosomal miRNA Profiling Reveals hsa‐miR‐7‐5p as a Key Regulator of Sperm Motility in Asthenozoospermia

open access: yesAndrology, EarlyView.
ABSTRACT Background Asthenozoospermia is a significant contributing factor to male infertility. Accumulating evidence indicates that impaired sperm motility is closely linked to dysregulated microRNA expression during spermatogenesis. Seminal plasma exosomes are enriched with diverse microRNAs, which play pivotal roles in modulating sperm motility, the

Update on male reproductive endocrinology. [PDF]

open access: yes, 2018
Practitioners of male reproductive and sexual medicine must have an intimate understanding of the physiology of male reproductive endocrinology, as such a knowledge is the cornerstone on which hormonal treatments are based.

Comprehensive Quantification of Oligoasthenozoospermia Induced by Obesity, Reproductive Toxicants, and Their Combination in Rat Models

open access: yesAndrology, EarlyView.
ABSTRACT Background Oligoasthenozoospermia is a leading cause of male infertility and has been increasingly associated with the global surge in obesity and exposure to reproductive toxicants. Despite extensive research on each factor individually, their combined pathological effects remain poorly understood.

Sperm Sexing in Selected Animals and Humans: Methods, Applications, and Future Prospects

open access: yesAndrology, EarlyView.
ABSTRACT Background Sperm sexing is a technique that enables the selection of offspring sex by sorting spermatozoa based on their sex chromosomes. This technology has gained increasing attention due to its potential applications in both animal breeding and human‐assisted reproduction.

Adult granulosa cell tumours of the testis analogous to ovarian counterparts are exceptionally rare: analysis of a multicentric series and review of the literature

open access: yesHistopathology, EarlyView.
Assessment of twenty testicular AGCTs with two different next‐generation sequencing (NGS) panels reveals differences with ovarian AGCTs, including absence of hotspot FOXL2 variants. Aims Testicular adult granulosa cell tumours (AGCTs) are rare and show several clinical–pathological differences with their ovarian counterparts.

Characterization and Functionality of Proliferative Human Sertoli Cells

open access: yesCell Transplantation, 2011
It has long been thought that mammalian Sertoli cells are terminally differentiated and nondividing postpuberty. For most previous in vitro studies immature rodent testes have been the source of Sertoli cells and these have shown little proliferative ...

Testicular mass frozen section examination: Pathological insights and diagnostic accuracy

open access: yesHistopathology, EarlyView.
Frozen section examination on testicular excisional biopsy is accurate and can help avoid unnecessary radical orchidectomy. A very high concordance rate between frozen section diagnosis and permanent diagnosis was obtained with no false negatives.

Transcriptional regulation of androgen receptor gene expression in Sertoli cells and other cell types [PDF]

open access: yes, 1992
Cooperative actions of FSH and androgens on initiation, maintenance, and restoration of spermatogenesis have been described. In the present experiments the regulatory effects of FSH on androgen receptor (AR) gene expression in ...
