Predictors of pain during oocyte retrieval

Journal of Psychosomatic Obstetrics and Gynecology, 2017
Introduction: Pain during oocyte retrieval remains prevalent despite detailed and specific pain management protocols. Exploring the role of psychosocial risk factors of pain during the oocyte retrieval could identify possible targets for prevention.

Manipulating Unisexual–Sexual Reproduction Transition to Engineer Genome‐Reconstructed Polyploids

Advanced Science, EarlyView.
This study developed an efficient approach to generate genome‐reconstructed polyploids involving unisexual gynogenetic Carassius gibelio, sexual C. auratus, and sexual C. cuvieri. The selected superior clone inherited gynogenesis ability of C. gibelio and herpesvirus resistance of wild C.

Effect of mitophagy in oocytes and granulosa cells on oocyte quality†

Biology of Reproduction, 2020
Abstract Mitophagy is the process by which cells selectively remove supernumerary or damaged mitochondria through autophagy, and is crucial for mitochondrial homeostasis and cell survival. Mitochondria play vital roles in determining the developmental competence of oocytes.

Equilibrium between anti‐oxidants and reactive oxygen species: a requisite for oocyte development and maturation

Reproductive Medicine and Biology, 2016
Reactive oxygen species (ROS) are required for cellular functioning and are controlled by anti‐oxidants. The ROS influence the follicles, oocytes, endometrium, and their environment.

Genomic Insights into the Origin, High Fecundity and Environmental Adaptation of Hu Sheep

Advanced Science, EarlyView.
The Hu sheep diverged from the Small‐tailed Han sheep ≈1330 years ago, and subsequently migrated from northern to warm and humid southern regions. The genes BMPR1B, UNC5C, and GRID2 play a synergistic role in the superior reproductive traits of Hu sheep.

Exocyst complex component 1 (Exoc1) loss in dormant oocyte disrupts c-KIT and growth differentiation factor (GDF9) subcellular localization and causes female infertility in mice

Cell Death Discovery
A limited number of female germ cells support reproduction in many mammals. The follicle, composed of oocytes and supporting granulosa cells, forms the basis of oogenesis.

Melatonin prevents postovulatory oocyte aging and promotes subsequent embryonic development in the pig

Aging, 2017
Oxidative stress is known as a major contributing factor involved in oocyte aging, which negatively affects oocyte quality and development after fertilization. Melatonin is an effective free radical scavenger and its metabolites AFMK and AMK are powerful

Intermediate Filament Protein BFSP2 Controls Spindle Formation via HSC70‐Mediated Stabilization of CLTC During Oocyte meiosis

Advanced Science, EarlyView.
Meiosis is a specialized form of cell division that has different regulation and mechanisms with mitosis in numerous aspects. Particularly, meiosis I is unique and occurs only in germ cells to separate homologous chromosomes. Thus, determining how this unusual chromosome segregation behavior is established is central to understanding germ cell ...

Oocyte-granulosa cell interactions during mouse follicular development: regulation of kit ligand expression and its role in oocyte growth

Reproductive Biology and Endocrinology, 2006
Ovarian folliculogenesis is regulated by both endocrine and intraovarian mechanisms that coordinate the processes of oocyte growth and somatic cell proliferation and differentiation.
