We previously demonstrated that the response to oxytocin is more robust in the uteri of proven breeder rats. This study investigates the contribution of T-type calcium channels (TTCCs) and L-type calcium channels (LTCCs) to the distinct response of virgin (V) and proven breeder (PB) rat uteri to oxytocin. Dose-inhibition responses to mibefradil (TTCC inhibitor) and verapamil (LTCC inhibitor) were conducted on isolated V and PB uterine strips. These experiments were followed by dose-response curves to oxytocin (10-10 to 10-5 M) in the presence of 10 µM of each inhibitor. Area-under-the-curve (AUC), amplitude, frequency, and duration of contractions were measured. V uteri generally showed a greater dependence on VGCCs, especially TTCCs. However, PB uteri exhibited a stronger frequency response to oxytocin. Blocking TTCCs had a more pronounced impact on the differential oxytocin response, particularly affecting the frequency component of contractions. The stronger frequency response in PB uteri may be due to a higher concentration of TTCCs in their myometrial pacemaker cells. This study provides supporting evidence that pregnancy induces lasting changes in uterine calcium handling. Our findings suggest that TTCCs play a more important role than LTCC in the parity-dependent differential response to oxytocin. The impact of ORAI and TRP channels still needs to be evaluated, to gain a more comprehensive understanding of the relative impact of voltage-gated calcium channels vs. storage-operated calcium entry channels on this phenomenon.</p>","PeriodicalId":20920,"journal":{"name":"Reproductive Sciences","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142979822","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since many men who take fluoxetine are of reproductive age and sperm are exposed to fluoxetine for a considerable time, this study aimed to examine the in vitro effects of fluoxetine on human sperm biochemical markers and sperm parameters. Semen samples from 30 fertile men were divided into three groups: a positive control group, a negative control group and a fluoxetine-treated group. We investigated sperm parameters, mitochondrial membrane potential (MMP), acrosome reaction, DNA fragmentation, chromatin integrity, and the expression of CASPASE8, CASPASE9, BAX, and BCL2 genes and proteins. Data were analyzed using repeated measures analysis. The results showed that the average percentage of motility, viability, MMP, acrosome and chromatin integrity, total antioxidant capacity (TAC) level, and BCL2 gene and protein expression in the fluoxetine group were significantly reduced compared to the positive and negative control groups. While the average percentage of non-progressive motility, sperm DNA fragmentation, malondialdehyde (MDA) level, reactive oxygen species (ROS), gene and proteins expression of CASPASE8, CASPASE9 and BAX increased significantly. This study suggests that fluoxetine may impair sperm quality by increasing the expression of apoptotic genes, proteins, and oxidative stress. Therefore, careful management of fluoxetine in treating depression is crucial, especially in men of reproductive age, due to its potential sexual side effects.

As an empirical illustration, analyses of prospectively longitudinal data with a nationally representative sample in the United Kingdom (National Child Development Study) show that women who experience pregnancy complications are significantly less likely to have another child and significantly more likely to have only one child. Our results suggest that increased chances of pregnancy complications that American women now experience alone can explain about 10% of the increase in the number of only children in the United States in the last half century.

We hypothesized that adding MMP9 alone would enhance myometrial contractions and that specific MMP9 inhibition would suppress uterine contractions. In myometrial tissue from women undergoing term Caesarean sections, we observed an increased contractile response as measured by area under the curve over time in tissues treated with MMP9 compared to vehicle-treated controls (p = 0.0003). This effect was primarily due to increased contraction frequency in MMP9-treated tissues compared to controls (p < 0.0001). Specific inhibition of MMP9 with the highly selective MMP9 inhibitor 1 (AG-L-66085) reduced contractile responses in myometrial tissues from pregnant women. We observed a reduction in the oxytocin-induced contractile response as measured by area under the curve over time (p < 0.0001) and contraction amplitude (p < 0.0068) in AG-L-66085-treated tissues compared to vehicle-treated controls. To determine the effects of MMP9 inhibition in the absence of exogenous oxytocin, we tested the effects of AG-L-66085 on spontaneous contractions. The area under the curve (p = 0.0415) and amplitude (p = 0.0354) of spontaneous contractions were reduced in response to 1 μM AG-L-66085, and the inhibitory effects increased as the AG-L-66085 concentration increased.

Thus, endometrial defects were frequently detected after adenomyomectomy and recovered over time, whereas one patient without endometrial restoration developed uterine rupture complicated by PAS.

A prospective study recruited 177 low-risk primigravida women. Ultrasound-based cAGV was calculated for all participants at 37 weeks. Participants were followed until the day of delivery; accordingly, they were divided into two groups: Control group (137/177) delivered at term (37 + 0/7-40 + 6/7) weeks and late-term group (40/177) who delivered at (41 + 0/7-41 + 6/7) weeks.

The participants' mean age was (27.32 ± 5.17) years.
