During in vitro fertilization-embryo transfer (IVF-ET), high sperm DFI can lead to a low fertilization rate, poor embryo development, early miscarriage, etc. A kinase anchoring protein (AKAP) is a scaffold protein that can bind protein kinase A (PKA) to subcellular sites of specific substrates and protects the biophosphorylation reaction. Sperm protein antigen 17 (SPA17) can also bind to AKAP. This study intends to explore the reason for the decreased fertilization rate observed in high sperm DFI (H-DFI) patients during IVF-ET. In addition, the study investigates the expression of AKAP, protein kinase A regulatory subunit (PKARII), and SPA17 between H-DFI and low sperm DFI (L-DFI) patients. SPA17 at the transcriptional level is abnormal, the translational level increases in H-DFI patients, and the expression of AKAP4/PKARII protein decreases. H 2 O 2 has been used to simulate oxidative stress damage to spermatozoa during the formation of sperm DFI. It indicates that H 2 O 2 increases the expression of sperm SPA17 protein and suppresses AKAP4/PKARII protein expression. These processes inhibit sperm capacitation and reduce acrosomal reactions. Embryo culture data and IVF outcomes have been documented. The H-DFI group has a lower fertilization rate. Therefore, the results indicate that the possible causes for the decreased fertilization rate in the H-DFI patients have included loss of sperm AKAP4/PKARII proteins, blocked sperm capacitation, and reduced occurrence of acrosome reaction.</p>","PeriodicalId":8483,"journal":{"name":"Asian Journal of Andrology","volume":" ","pages":"25-33"},"PeriodicalIF":3.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10846834/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10258205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this systematic analysis was to synthesize the evidence regarding whether men diagnosed with male factor infertility experience greater psychological distress than (1) men described as fertile and (2) men in couples with other infertility diagnoses. Online databases were searched using a combination of Medical Subject Headings (MeSH) headings and keywords relating to male infertility and psychological distress. The search yielded 1016 unique publications, of which 23 were included: 8 case-control, 14 prospective cohort, and 1 data linkage studies. Seven aspects of psychological distress were identified depression, anxiety, self-esteem, quality of life, fertility-related stress, general psychological stress or well-being, and psychiatric conditions. Case-control studies reported that men with male factor infertility have more symptoms of depression, anxiety and general psychological distress, worse quality of some aspects of life, and lower self-esteem than controls. When men with male factor infertility were compared to men in couples with other causes of infertility, there were few differences in the assessed aspects of psychological distress.

A hyperlipidemia model was established using 27 eight-week-old male Sprague-Dawley (SD) rats fed a high-fat and high-cholesterol diet (hyperlipidemic rats, HR). In addition, 9 male SD rats were fed a normal diet to serve as controls (NC).

Subsequently, the lipid profiles, erectile function, oxidative stress, phenotypic modulation markers of CCSMCs, and tissue histology were analyzed. The experimental results revealed that erectile function was significantly impaired in the HR and HR + NS groups, but enhanced in the HR + NAC group. Abnormal lipid levels, over-activated oxidative stress, and multi-organ lesions observed in the HR and HR + NS groups were improved in the HR + NAC group. Moreover, the HR group showed significant phenotypic modulation of CCSMCs, which was also inhibited by NAC treatment.

In our research from June 2020 to April 2021, we examined the accuracy of self-reported sexual function scales. We invited patients from the Department of Infertility and Sexual Medicine at the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China), who have male sexual dysfunction, to participate by filling out a self-reported version of a specific questionnaire. In addition, they went through a clinician-assisted version of this questionnaire, encompassing tools such as the Premature Ejaculation Diagnostic Tool (PEDT), the 6-item International Index of Erectile Function (IIEF-6), the Erection Hardness Scale (EHS), and the Masturbation Erection Index (MEI). Using the clinician-assisted version as a reference, we categorized patients and applied various statistical methods, such as the Chi-square test, intraclass correlation coefficient (ICC), logistic regression, and the Bland–Altman plot, to gauge reliability. In our study with 322 participants, we found that while there were no notable discrepancies in error rates based on our categorization, certain scales showed significant differences in terms of overestimation and underestimation, with the exception of the PEDT. The positive diagnosis rate consistency between the self-reported and clinician-assisted versions was observed. High ICC values between the two versions across the scales were indicative of remarkable reliability. Our findings show that the self-reported versions of tools such as EHS, IIEF-6, MEI, and PEDT are credible and hold clinical reliability.
