Gonadal development in scorpion mud‐turtles, Kinosternon scorpioides, in a controlled environment

The Anatomical Record, EarlyView.
Stage 20 was identified as the critical point for gonadal differentiation in Kinosternon scorpioides, providing key insights into sex determination. These findings enhance conservation strategies by supporting reproductive management and population viability in both in situ and ex situ programs. Abstract Research on gonadal development including sexual

Unraveling ovarian histology: The key morphological aspects that spur the development of the Fossa ovarii in equine

The Anatomical Record, EarlyView.
Abstract The equine ovary exhibits unique structural and developmental features that distinguish it from those of other domestic species, including the presence of an ovulation fossa and an inversion of cortical and medullary layers. This study aimed to investigate the morphostructural development of the equine fetal ovary, with particular emphasis on ...

Donation of oocytes as treatment for infertility in patients with premature ovarian failure: awarded the "Nicolau de Moraes Barros" prize for gynecology

São Paulo Medical Journal
A total of 7 cycles of embryo transfer by oocyte donation were performed on 5 patients with premature ovary failure (POF). All donors were under 35 of age and the recipients average age was 38.6 years.

Establishment of Interspecies Somatic Cell Nuclear Transfer and Transgene‐Free Inducible Pluripotent Stem Cells for Versatile Conservation of the Germplasm Resource of Wild Boar

Animal Research and One Health, EarlyView.
Conserving genetic material and even increasing genetic diversity is critical. To conduct the conservation of wild boar germplasm resources, we have successfully obtained healthy cloned wild boars for the first time using interspecies somatic cell nuclear transfer and established transgene‐free iPSCs that can be used to conduct iterative rounds of gene

The end of fertility: age, fecundity and fecundability in women [PDF]

, 2017
Onset of capacity for childbearing in women is dated biologically by menarche, although actual onset may be delayed. The end of childbearing is less understood but recent demographic and biological research on fertility at older ages is clarifying the ...

Genomic Structural Variations Provide Insights Into Litter Size and Teat Number Traits in Hu Sheep

Animal Research and One Health, EarlyView.
Here, we conducted whole genome sequencing on 300 Hu sheep with an average depth of 16.51X. Two candidate genes associated with litter size and teat number traits were identified, namely MAST2 and AFDN. ABSTRACT Litter size and the teat number are important economic indicators in sheep production.
