Donkey Epididymal Transport for Semen Cooling and Freezing

Animals, 2020
The objectives of this study were to assess the cooling and freezing of donkey epididymal semen harvested immediately after castration (Experiment 1, n = 4) or after the shipment (24 or 48 h) of epididymides attached to testicles (Experiment 2, n = 14 ...

Factors associated with the reproductive performance of ewes inseminated laparoscopically in England and Wales: A longitudinal study

Veterinary Record, EarlyView.
Abstract Background Laparoscopic intrauterine artificial insemination (Lap‐AI) is used in sheep genetic improvement programmes. However, the lambing rate (LR) (i.e., the proportion of inseminated ewes that lamb) following Lap‐AI is variable. Previously, one small UK study investigated factors associated with LR, but it did not adjust for dependencies ...

An engineered epididymal cell line provides a sustainable source of functional extracellular vesicles for in vitro sperm preservation: A multi‐omics and functional study

VIEW, EarlyView.
ABSTRACT This study investigated the function of epididymal extracellular vesicles (EVs) in overcoming sperm post‐testicular modification deficiencies. Although EVs derived from the epididymis play a crucial role in intercellular communication and molecular exchange, there is limited research addressing how EVs released by in vitro cultured epididymal ...

Exploring the impact of microbial dysbiosis on ovarian cancer and the therapeutic potential of probiotics

VIEW, EarlyView.
Ovarian cancer has been linked to the microbiome as a potential environmental contributor, but how this association relates to tumor progression remains unclear. By comparing tumor and nontumor tissues, we identified a severity‐associated microbial and metabolic signature and showed that probiotics can partially restore immune balance and slow tumor ...

Primary leiomyosarcoma of epididymis

Journal of Cancer Research and Therapeutics, 2012
Primary leiomyosarcomas rarely arise from epididymis. But they are the most common histopathological types of sarcoma arising from the epididymis. Primary epididymal leiomyosarcoma occurs usually in older patients. We report a young patient of 35 years presenting with leiomyosarcoma of left epididymis.

First Vasectomy Procedure Successfully Performed on a Southern African Male Giraffe (Giraffa camelopardalis giraffa)

Zoo Biology, EarlyView.
First successful vasectomy in a southern African male giraffe, Giraffa camelopardis giraffa ABSTRACT This study reports the first successful vasectomy on a southern African male giraffe (Giraffa camelopardalis giraffa). The goal of the procedure was to create a teaser male for reproductive studies.

Luteinizing hormone receptor knockout mouse: What has it taught us?

Andrology, EarlyView.
Abstract Luteinizing hormone (LH), along with its agonist choriongonadotropin (hCG) in humans, is the key hormone responsible for the tropic regulation of the gonadal function. LH and hCG act through their cognate receptor, the luteinizing hormone/choriongonadotropin receptor (LHCGR; more appropriately LHR in rodents lacking CG), located in the testis ...

The effects of prepubertal epididymal ligation upon androgen receptor distribution in the rat caput epididymis

Veterinární Medicína, 2011
The aim of the present study was to investigate the androgen receptor (AR) distribution in epididymal cells of developing rats and the effects of prepubertal epididymal obstruction upon AR distribution in the rat caput epididymis.

The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

CRISPR/Cas9‐mediated Genome‐editing Reveals 10 Testis‐enriched Genes and One Non‐testis‐enriched Gene are Dispensable for Male Fecundity in Mice

Andrology, EarlyView.
ABSTRACT Background More than 1000 genes have been identified as predominantly expressed in the human testis. Advances in gene editing technologies have enabled the rapid and efficient generation of genetically engineered mice. This approach facilitates the screening of genes essential for spermatogenesis by analyzing knockout mouse models.
