Anti‐Müllerian hormone concentrations in female rabbits and its relation to spay status, pseudopregnancy and ovarian follicle numbers

open access: yesReproduction in Domestic Animals, Volume 57, Issue 12, Page 1636-1643, December 2022., 2022
Abstract Anti‐Müllerian hormone (AMH), known for its role during foetal sexual differentiation, is secreted by the Sertoli cells in males and the granulosa cells in females during post‐natal life. As serum AMH concentrations correlate with follicle numbers, AMH is utilized as a marker of ovarian reserve in many species. In dogs and cats, AMH is used as

Morphological variations of the ovarian follicles and oviduct of commercial Lohmann Brown and indigenous Potchefstroom Koekoek breeds

Abstract Egg laying begins with the orderly development of follicles in the chicken ovaries and transportation through the oviduct with deposition of nutrients until the eggs are produced. However, the ovarian follicles and oviduct morphology of Lohmann Brown and Potchefstroom Koekoek laying hens have not yet been studied.

The post‐ovulatory rise in progesterone is lower and the persistence of oestrous behaviour longer during the first compared with the second cycle of the breeding season in mares

open access: yesReproduction in Domestic Animals, Volume 58, Issue 1, Page 141-145, January 2023., 2023
Abstract Mares are seasonally polyoestrous breeders. Therefore, the first ovulation of the season, following winter anoestrus, is the only cycle in which mares ovulate without the presence of an old CL from the previous cycle. The objective of this study was to compare the length of oestrous behaviour, and plasma progesterone concentrations during the ...

Ectogenesis and gender inequality: Two pathways converge

open access: yesBioethics, EarlyView.
Abstract Debate on whether ectogenesis is a morally desirable solution to gender inequality often starts by analyzing whether gender inequality has been caused by (i) reproductive differences between the sexes or (ii) social structures.

In some places, period (or menstrual hygiene management [MHM]) products are free and readily found in restaurants, universities and pubs. However, conversations on mensuration management have also led to discussions on sustainability.

The DCIDE framework: systematic investigation of evolutionary hypotheses, exemplified with autism

open access: yesBiological Reviews, EarlyView.
ABSTRACT Evolutionary explanations of mental disorders are a longstanding aim of evolutionary psychiatry, but have suffered from complexities including within‐disorder heterogeneity and environmental effects of contemporary societies obscuring possible ancestral functions.
