Functional Sex Reversal in Adult Gonochoristic Teleosts is Mediated by Ovarian Germline Stem Cell Plasticity and Somatic Cell Transdifferentiation

Advanced Science, EarlyView.
Oocytes play crucial roles in maintaining ovarian fate in adult gonochoristic fish. Targeted oocyte ablation with aromatase inhibition triggers the activation of surviving germline stem cells and the transdifferentiation of somatic cells from granoulosa/theca to Sertoli/Leydig lineages, inducing a complete and functional female‐to‐male sex reversal ...

Lactation, Childrearing, and Gender Justice

Journal of Applied Philosophy, EarlyView.
ABSTRACT In this article, I discuss the significance of early infant feeding choices for the goal of gender justice. Focusing on human lactation practices, I identify Exclusive Gestational Nursing (EGN) as the norm in advanced industrial societies, which creates the expectation and permission for gestators, and only gestators, to nurse children, and ...

The Australian Hydromyine Rodents—Their Interspecific Diversity and Reproductive Biology: A Review

Integrative Zoology, EarlyView.
There are two major groups, the Rattus species and the Hydromyini, in Australia. Clearly, the hydromyine rodents, unlike the Rattus genus, exhibit a diverse array of reproductive biological traits in both males and females, the full evolutionary significance of which has yet to be ascertained.

Legal Issues in Nonsurgical Human Ovum Transfer

, 1984
Human ovum transfer is a new reproductive technology in which a not-yet-implanted fertilized ovum is removed by catheter from the uterus of an artificially inseminated ovum donor for transfer to the semen donor's infertile wife.

Early‐Life Telomere Length Negatively Covaries With Brood Size and Father Age, and Predicts Long‐Term Survival in Male Barn Swallows (Hirundo rustica)

Integrative Zoology, EarlyView.
In barn swallows, nestlings raised in larger broods or by older social fathers have shorter telomeres, and those with longer telomeres tend to live longer, suggesting that early‐life conditions may shape individual lifespan through telomere dynamics. ABSTRACT Parental decisions on breeding, such as brood size and timing of reproduction, influence the ...

Black Carp Mylopharyngodon piceus reproductive development and maturation in the Mississippi River basin

Journal of Fish Biology, EarlyView.
Abstract Black Carp Mylopharyngodon piceus are native to most major east Asian drainages and are internationally cultured for use as a food‐fish or a biological control for molluscs. We describe the reproductive biology of Black Carp from the growing invasive population in the Mississippi River basin through examination of incidental commercial ...

TMEM16A chloride channels in the female reproductive tract and their role in normal and dysfunctional pregnancy and labour

The Journal of Physiology, EarlyView.
Abstract figure legend TMEM16A plays a pivotal role in setting the duration of the action potential plateau in human uterine smooth muscle. An increase in TMEM16A expression in labour underpins a lengthening of the plateau and this provides time for the contraction to become larger and longer, important for timely successful labour.

Reproduction on the Rocks: Life History of a Freshwater Macrobioeroding Bivalve

Ecology and Evolution, Volume 16, Issue 9, September 2026.
ABSTRACT Macrobioerosion, the excavation and removal of consolidated mineral substrates by macrofauna, is well established in marine systems, where macrobioeroders drive carbonate cycling, sediment production and habitat formation. In freshwater ecosystems, however, it has been documented in only a small number of invertebrate taxa and remains a poorly
