The reproductive cycle of was studied over two years in Redondela (NW Spain), considering both the monthly evolution of the percentage of individuals with oocytes and the variation of the mean oocyte size. Moreover, since three other species of have recently been documented in regions geographically close to NW Spain, we first confirmed the identity of this species by carrying out a morphological identification of a representative number of the specimens collected. Our data showed a discontinuous reproductive season, with a period of proliferation and maturation of oocytes from January to September and asynchronous spawning events between July and October. Then, a resting period in the months of November and December was observed. We also explored the influence of some relevant environmental factors (namely, water temperature, photoperiod, salinity, primary production and upwelling index) on the observed reproductive cycle. The results suggest that water temperature is one of the most important drivers of the reproductive cycle for this species. Particularly, in Ría de Vigo, the reproductive cycle seems to be influenced by upwelling events of deep cold water that occur frequently between March and September, and that could act as a spawning-inducing switch.

Gonadotropin Releasing Hormone Agonists Combined with Hormone Replacement Therapy Significantly Improves Reproductive Outcomes for Patients with Thin Endometrium and Intramural Fibroids in Frozen Embryo Transfer Cycles.

People's Hospital of Zhengzhou University, Zhengzhou, Henan, 45003, People's Republic of China.
Background: Both intramural myomas and thin endometrium exert a detrimental influence on the outcomes of assisted reproductive technology (ART). The downregulation of gonadotropin releasing hormone agonists (GnRH-a) is regarded as an effective approach to reducing the size of intramural fibroids and enhancing endometrial receptivity. Consequently, we conducted this study to assess whether the GnRH-a combined with hormone replacement therapy (GnRH-a-HRT) can improve reproductive outcomes in frozen embryo transfer cycles for patients with a thin endometrium (≤7 mm) and intramural fibroids.

Background: The safety and effectiveness of short-term insemination remain a subject of controversy. This study aims to investigate the impact of short-term insemination on both embryo quality and pregnancy outcomes and whether it is necessary to apply short-term insemination to all patients underwent in vitro fertilization (IVF).
Methods: A retrospective analysis was conducted on 3,496 patients from two centers over the period January 2016 to December 2022.
Comparison of Cumulative Live Birth Rates Between Progestin and GnRH Analogues in Preimplantation Genetic Testing Cycles.

Center for Reproductive Medicine, Guangdong Women and Children Hospital, Guangzhou 511400, Guangdong Province, China.
Context: Progestins have recently been used as an alternative for gonadotropin-releasing hormone (GnRH) analogues to prevent premature luteinizing hormone surge due to the application of vitrification technology. However, the long-term efficacy and safety of a progestin-primed ovarian stimulation (PPOS) regimen, including oocyte competence, cumulative live birth rate (LBR), and offspring outcomes, remain to be investigated.
Objective: To compare cumulative LBR of preimplantation genetic testing (PGT) cycles between a PPOS regimen and GnRH analogues.

This study aimed to investigate the mechanism by which Se in regulates the proliferation and apoptosis of sheep Leydig cells via the miR-200a/NRF pathway. The cells were isolated and purified from the testes of 8-month-old sheep via a Percoll density gradient. After the cells were treated with different concentrations of Se (0, 2.

A novel strategy for cytochrome c selective recognition assisted with cucurbit[6]uril by host-guest interaction via N-terminal epitope imprinting and reversible addition-fragmentation chain transfer (RAFT) polymerization was developed. N-terminal nonapeptide of cytochrome c (GI-9) was used as the epitope template to achieve highly selective recognition of cytochrome c. As a common supramolecule in recent years, cucurbit[6]uril can encapsulate the butyrammonium group of lysine residue to capture the peptide and improve the corresponding spatial orientation by the host-guest interaction for GI-9 or cytochrome c recognition.
