Adaptive divergence in reproductive seasonality and underlying physiological features fit Rattus norvegicus to live as opportunistic breeders

Integrative Zoology, EarlyView.
Brown rats living at different latitudes have evolved reproductive patterns adapted to their local environments. Besides expected adaptive divergence in seasonality, a distinct regulating mechanism from typical seasonal breeders reveals how brown rats benefit from quicker semen production to live as opportunistic breeders.

Intracytoplasmic sperm injection outcome using ejaculated sperm and retrieved sperm in azoospermic men. [PDF]

, 2008
Introduction:We aimed to determine pregnancy and miscarriage rates following intracytoplasmic sperm injection (ICSI) cycles using retrieved epididymal and testicular sperm in azoospermic men and ejaculated sperm in oligospermic and normospermic men ...

cba‐miR‐222‐3p involved in photoperiod‐induced apoptosis in testes of striped hamsters by targeting TRAF7

Integrative Zoology, EarlyView.
The cba‐miR‐222‐3p affects the MAPK signaling pathway by targeting TRAF7, thereby participating in the induction of apoptosis in the testes of striped hamsters under different photoperiods. Abstract The role of miRNAs in the regulation of seasonal reproduction in rodents, particularly in relation to photoperiod changes, is still poorly understood ...

Features of reproduction and assisted reproduction in the white (Ceratotherium simum) and black (Diceros bicornis) rhinoceros [PDF]

, 2015
Despite the worldwide increase of rhinoceros calf numbers, the growth of the population of white and black rhinoceros is slowing down mainly due to anthropogenic causes, such as poaching and habitat loss.

Rapid detection of mouse spermatogenic defects by testicular cellular composition analysis via enhanced deep learning model

Andrology, EarlyView.
Abstract Background Histological analysis of the testicular sections is paramount in infertility research but tedious and often requires months of training and practice. Objectives Establish an expeditious histopathological analysis of mutant mice testicular sections stained with commonly available hematoxylin and eosin (H&E) via enhanced deep learning

Assessment of anti-sperm antibodies in couples after testicular sperm extraction

Clinical and Investigative Medicine, 2011
Purpose Testicular spermatozoa can be retrieved successfully by the testicular sperm extraction (TESE) procedure and used for intracytoplasmic sperm injection. Disruption in the blood-testis barrier can lead to the production of antisperm antibodies (ASA).

Dexamethasone is a regulator of clock genes in testicular peritubular cells

Andrology, EarlyView.
Abstract Background We recently found that peritubular cells of the human testis are a dominant site of expression of the glucocorticoid receptor (GR; encoded by NR3C1). Activation of GR by dexamethasone (Dex) strongly influences the phenotype of cultured human testicular peritubular cells (HTPCs), causing massive changes of their proteome and ...

Evaluation of Spermatozoal Rna Extraction Methods [PDF]

, 2016
The study was aimed to compare different RNA isolation methods from sperm and testicular tissue. A suitable sperm purification technique is required as sperm RNA yield is strongly correlated with the number of sperms.

Effect of oral methyl-t-butyl ether (MTBE) on the male mouse reproductive tract and oxidative stress in liver [PDF]

, 2008
MTBE is found in water supplies used for drinking and other purposes. These experiments follow up on earlier reports of reproductive tract alterations in male mice exposed orally to MTBE and explored oxidative stress as a mode of action.

Healthy and unhealthy dietary patterns and sperm quality from the Led‐Fertyl study

Andrology, EarlyView.
Abstract Background Dietary patterns may affect sperm quality, but the scientific evidence is limited. Objective To evaluate the association between adherence to different a‐priori dietary patterns and sperm quality parameters in healthy reproductive‐age men.
