Abstract
A comprehensive understanding of the complex regulatory mechanisms governing estrus and ovulation across multiple tissues in mammals is imperative to improve the reproductive performance of livestock and mitigate ovulation-related disorders in humans. To comprehensively elucidate the regulatory landscape, we analyzed the transcriptome of protein-coding genes and long intergenic non-coding RNAs (lincRNAs) in 58 samples (including the hypothalamus, pituitary, ovary, vagina, and vulva) derived from European Large White gilts and Chinese Mi gilts during estrus and diestrus. We constructed an intricate regulatory network encompassing 358 hub genes across the five examined tissues. Furthermore, our investigation identified 85 differentially expressed lincRNAs that are predicted to target 230 genes associated with critical functions including behavior, receptors, and apoptosis. Importantly, we found that vital components of estrus and ovulation events involve "Apoptosis" pathway in the hypothalamus, "Autophagy" in the ovary, as well as "Hypoxia" and "Angiogenesis" in the vagina and vulva. We have identified several differentially expressed transcription factors (TFs), such as SPI1 and HES2, which regulate these pathways. SPI1 may suppress transcription in the autophagy pathway, promoting apoptosis and inhibiting the proliferation of ovarian granulosa cells. Our study provides the most comprehensive transcriptional profiling information related to estrus and ovulation events.

[PMID: 36710334 PMCID: PMC9885692 DOI: 10.1186/s12958-023-01069-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Accepted: 01/25/2023] [Indexed: 01/31/2023] Open
Abstract
Ovarian stimulation (OS) is one of the key factors in the success of in vitro fertilization-embryo transfer (IVF-ET), by enabling the recruitment of numerous healthy fertilizable oocytes and, thereby, multiple embryos. The Stop GnRH-agonist/GnRH-antagonist (GnRH-ag/GnRH-ant), which offers all the advantages of using long suppressive GnRH-ag, with GnRH-ant, is in my opinion a valuable addition to the armamentarium of OS protocols. It allows cycle programming, better follicular synchronization and offers successful outcome in a variety of challenging cases such as poor responders, Poseidon group 4 poor prognosis patients, those with elevated peak progesterone (P) serum levels, poor embryo quality or repeated IVF failures.

[PMID: 36457798 PMCID: PMC9679556 DOI: 10.1515/med-2022-0594] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2022] [Revised: 07/05/2022] [Accepted: 10/08/2022] [Indexed: 11/20/2023] Open
Abstract
We conducted a systematic review and meta-analysis of all published data to determine the impact of estradiol pretreatment on reproductive outcomes and ovary stimulation characteristics for in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatment with gonadotropin-releasing hormone (GnRH) antagonist protocol. MEDLINE, EMBASE, Cochrane Library, Web of Science, and China National Knowledge Infrastructure were searched, and any randomized controlled trials associated with estradiol pretreatment in GnRH antagonist protocol were included. Seven studies (1,236 patients) were included in the present study. The pooled data from the meta-analysis demonstrated no significant difference in ongoing pregnancy rate (odds ratio (OR): 0.92 (95% CI: 0.69-1.21; P = 0.53) and live birth rate OR: 0.98 (95% CI: 0.74-1.30; P = 0.90) between patients with and those without estradiol pretreatment in GnRH antagonist protocol. Duration of gonadotropin exposure, gonadotropin consumption, and the number of cumulus-oocyte complexes were not significantly different between groups. Luteal estradiol pretreatment in IVF/ICSI cycles with GnRH antagonist protocol in normal ovary responding population does not affect the reproductive outcomes. It is an encouraging option to facilitate cycle scheduling in GnRH antagonist protocol, for luteal estradiol pretreatment does not increase the duration of gonadotropin exposure or gonadotropin consumption.

J Assist Reprod Genet 2022; 39:291-303. [PMID: 35306603 PMCID: PMC8956771 DOI: 10.1007/s10815-021-02359-y] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2021] [Accepted: 11/15/2021] [Indexed: 02/03/2023] Open
Abstract
PURPOSE This systematic review aimed to identify baseline patient demographic and controlled ovarian stimulation characteristics associated with a suboptimal response to GnRHa triggering, and available options for prevention and management of suboptimal response. METHODS PubMed, Google Scholar, Medline, and the Cochrane Library were searched for keywords related to GnRHa triggering, and peer-reviewed articles from January 2000 to September 2021 included. RESULTS Thirty-seven studies were included in the review. A suboptimal response to GnRHa triggering was more likely following long-term or recent oral contraceptive use and with a low or high body mass index. Low basal serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol serum levels were correlated with suboptimal oocyte yield, as was a low serum LH level on the day of triggering. A prolonged stimulation period and increased gonadotropin requirements were correlated with suboptimal response to triggering. Post-trigger LH < 15 IU/L best correlated with an increased risk for empty follicle syndrome and a lower oocyte retrieval rate. Retriggering with hCG may be considered in patients with suboptimal response according to post-trigger LH, as in cases of failed aspiration. CONCLUSION Pre-treatment assessment of patient characteristics, with pre- and post-triggering assessment of clinical and endocrine cycle characteristics, may identify cases at risk for suboptimal response to GnRHa triggering and optimize its utilization.
