Modified cytoskeletal and extracellular matrix composition in the canine testis after long‐acting gonadotropin‐releasing hormone agonist deslorelin treatment

Andrology, EarlyView.
Abstract Background Long‐acting gonadotropin‐releasing hormone (GnRH) agonists are commonly used for fertility control in male dogs. Their effect on testicular histomorphology has not been clarified. Objectives To elucidate the mechanisms underlying androgen withdrawal in response to long‐acting GnRH agonist deslorelin 4.7 mg treatment on testicular ...

INSL3 Expression in Leydig Cells is a Biomarker for Immunocastration in Boars: Transcriptional Evidence

Andrology, EarlyView.
ABSTRACT Background Study aimed to obtain insights into physiological responses to immunocastration in pubertal boars by evaluating effects of alternative vaccination protocols and identifying a reliable immunocastration biomarker. Objectives It was hypothesized that the timing of gonadotropin‐releasing hormone (GnRH) suppression by immunocastration ...

The threshold of estradiol level for fresh embryo transfer differs between blastocyst and cleavage‐stage embryo

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
Our results suggested that the difference in pregnancy outcomes between fresh and frozen embryo transfer is related to the peak estradiol level and embryo transfer stage. The cutoff values for peak estradiol level for performing freeze‐all strategy to improve pregnancy outcomes were different for cleavage‐stage and blastocyst‐stage embryo transfer ...

Response to an estradiol-based fixed-time artificial insemination (FTAI) protocol in postpartum beef cows: interaction between the ovulatory inductor and the genotype [PDF]

Journal of Central European Agriculture
To evaluate if the ovulatory inducer, the genotype, and their interaction affect the reproductive response to a fixed-timed artificial (FTAI) protocol and to determine whether this protocol improves the breading season pregnancy rate (PR), a total of 242

Urinary tract events after radical radiotherapy (RT) for prostate cancer according to pre‐RT International Prostate Symptom Score

BJU International, EarlyView.
Objective To describe the risk of urinary tract events after radical radiotherapy (RT) according to pre‐RT (IPSS) overall and within subgroups of prostate volume, type of RT, and use of neoadjuvant androgen‐deprivation therapy (ADT), as men who undergo RT for prostate cancer have a risk of urinary tract events.

Homo sapiens, industrialisation and the environmental mismatch hypothesis

Biological Reviews, EarlyView.
ABSTRACT For the vast majority of the evolutionary history of Homo sapiens, a range of natural environments defined the parameters within which selection shaped human biology. Although human‐induced alterations to the terrestrial biosphere have been evident for over 10,000 years, the pace and scale of change has accelerated dramatically since the onset
