A valuable predictive model for optimizing the timing of oocyte retrieval: a retrospective analysis of oocyte retrieval time in 49,961 oocyte pickup (OPU) cycles

Reproductive Biology and Endocrinology
Background In clinical practice, scheduling oocyte retrieval is a challenging issue that requires comprehensive consideration of factors such as the woman's age, ovarian response, hormone levels and other variables.

Impact of donor mare and stallion identity on the likelihood of pregnancy after transfer of in vitro produced embryos

Equine Veterinary Journal, EarlyView.
Abstract Background The success of in vitro embryo production (IVEP) is influenced by donor mare and stallion. Objectives To determine whether donor mare and stallion influence the pregnancy rate after transfer of in vitro produced (IVP) blastocysts and to identify factors influencing the likelihood of obtaining one or more pregnancies from a single ...

Short- and Long-Term Storage of Non-Domesticated European Mouflon (Ovis aries musimon) Cumulus–Oocyte Complexes Recovered in Field Conditions

Animals
Reproductive biotechnologies can be used as a supporting tool, through gamete conservation and in vitro embryo production, in the preservation of invaluable and irreplaceable animal genetic resources. In the present study, immature mouflon cumulus–oocyte

Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

Equine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.

The Importance of the Position of the Nucleus in Drosophila Oocyte Development

Cells
Oogenesis is a developmental process leading to the formation of an oocyte, a haploid gamete, which upon fertilisation and sperm entry allows the male and the female pronuclei to fuse and give rise to a zygote.

Veterinarian and breeder perspectives surrounding ovum pick‐up and intracytoplasmic sperm injection in mares: A survey study

Equine Veterinary Journal, EarlyView.
Abstract Background There is an ethical debate about the application of ovum pick‐up (OPU) and intracytoplasmic sperm injection (ICSI) in mares. Objectives To survey the opinions of equine veterinarians and breeders of sport horses on the ethics of using OPU–ICSI in mares. Study Design Cross‐sectional descriptive study.

Exceptional longevity of mammalian ovarian and oocyte macromolecules throughout the reproductive lifespan

eLife
The mechanisms contributing to age-related deterioration of the female reproductive system are complex, however aberrant protein homeostasis is a major contributor.

Support and destigmatization in early pregnancy loss in Spain

Feminist Anthropology, EarlyView.
Abstract Early miscarriages are a frequent reproductive event, often silenced and shrouded in stigma. Feminist anthropology has pointed out how such losses challenge the widespread Euro‐American social representations of motherhood and pregnancy, as well as societal unease with death.

CPEB3 Maintains Developmental Competence of the Oocyte

Cells
Mammalian oocyte development depends on the temporally controlled translation of maternal transcripts, particularly in the coordination of meiotic and early embryonic development when transcription has ceased.

Somatic cell reprogramming for Parkinson's disease treatment

Ibrain, Volume 11, Issue 1, Page 59-73, Spring 2025.
The fundamental purpose of cell reprogramming to treat Parkinson's disease is to generate dopaminergic neurons (DAN) and do transplantation. There are two ways to accomplish this. One method is to induce cells into induced DA neurons (iDAN) directly or to induce cells into induced pluripotent stem cells and ultimately into iDAN in vitro. Another option
