Summary: The study showed that oral estradiol plus vaginal progesterone leads to increased endometrial thickness and a higher risk of endometrial hyperplasia, suggesting the need for further investigation into alternative doses or frequencies of administration for adequate endometrial protection from estrogen therapy in postmenopausal women.

Summary: Progesterone hormone acts through classical and non-classical receptors in the female reproductive system, affecting menstrual cycle, pregnancy, and parturition. These receptors regulate cell responses through different signaling pathways, playing a crucial role in female reproductive tissues.

Summary: This study uses thermal imaging to investigate how nesting female hummingbirds maintain energy balance while incubating their eggs and brooding their chicks. The research found that nesting females usually avoid torpor and instead reduce their own energy requirements by utilizing the warm nest environment and possibly shallow torpor, prioritizing the needs of their offspring.

Summary: Vaginal cytology is an important examination method in gynecological disorders and cycle staging in dogs. Despite the challenges in evaluation and inconsistent definitions, it remains a useful diagnostic tool. To address the issue of evaluation consistency, a tutorial was developed to guide users in systematically assessing specific cell characteristics.

Summary: Climate warming has major consequences for animal populations, as it can affect their physiology and behavior. This study found that individuals raised in heated roosts grew significantly larger than those raised in unheated conditions, suggesting that metabolic savings in warmer conditions lead to increased body size. This has potential consequences for population persistence.

Summary: This study found that gestational exposure to BHT inhibits decidualization of mouse endometrium during early pregnancy, resulting in a decrease in the number of implantation sites and uterine weight. Additionally, BHT suppressed the decidual morphology of endometrial stromal cells and significantly decreased the expression of decidual markers. Furthermore, BHT exposure led to upregulation of reproductive hormones and hormone receptor signals in early pregnancy.

Summary: A study on 1,048 pregnant women found that vaginal micronized progesterone significantly reduces the risk of preterm birth in women with a shortened cervix in the second trimester; there was no significant difference in the effectiveness of vaginal gel and vaginal capsules containing micronized progesterone for preventing preterm birth.

Summary: This study developed a competitive ELISA for measuring FSH concentrations in plasma samples from green sea turtles. The ELISA was used to study the reproductive cycles and correlations between FSH and hormonal steroid concentrations. The findings provide important insights into the functions of gonadotropins and their effects on reproduction in green sea turtles.

Summary: Torpor/hibernation in mammals involves a reduction in metabolic rate and body temperature, which can also be induced in non-hibernating animals by manipulating brainstem neurons or activating adenosine A1 receptors. This synthetic torpor state has potential applications in medicine and space exploration, offering benefits for biological adaptation to space environments and increased protection from cosmic rays. Further testing 'in the field', possibly on the International Space Station, is recommended to fully understand the physiological advantages of synthetic torpor in space.

Summary: The study investigated how a more bioavailable dietary Mn source can influence luteal function by altering the abundance of protein and mRNA involved in steroidogenesis. It was found that gilts fed Mn-amino acid complex had downregulated proteins related to P-4 signaling and cholesterol synthesis in the CL, and decreased transcript abundance of genes encoding steroidogenic enzymes in the CL tissue compared to controls.

Summary: The experiment aimed to identify pregnant goats through maximum progesterone milk levels and determine the optimal moment to apply lactation inhibitors for drying off lactating goats. The results showed that it is difficult to reliably detect pregnancy through progesterone levels in milk, except for goats gestating four foetuses. The fertility of goats is not affected by milk yield at mating until it reaches at least 3250 mL/day, and the application of lactation inhibitors would be most effective from the 10th week post-mating.

Summary: This study describes the management of vaginal hyperplasia in bitches using Buhner vulvar suture. The technique proved to be effective in preventing the recurrence of the protrusion during the current estrus cycle. It is a conservative treatment for medium- and large-sized dogs without any signs of trauma or ulceration.

Summary: This study compares the vaginal microbial communities of ewes before and during gestation, finding significant changes in species richness and diversity. It suggests that higher microbial diversity in pregnant ewes may indicate a more stable environment driven by pregnancy. Additionally, certain bacterial phylotypes present at specific time points may have a beneficial effect on pregnancy outcome.

Summary: Preterm birth is a major cause of infant morbidity and mortality worldwide. Advances in nanomedicine have allowed for the delivery of drugs to the female reproductive tract through vaginal administration, providing new possibilities for treating preterm birth. Studies using murine models have also provided insights into the role of the cervix in pregnancy and parturition. These recent developments indicate a paradigm shift in the field of reproductive biology for treating preterm birth.

Summary: This study aimed to compare the effects of injectable or intravaginal progesterone on reproductive performance and serum progesterone concentration in ewes. The results showed that ewes treated with intravaginal progesterone had a higher estrus rate and a higher pregnancy rate early in the breeding season.

Summary: This study investigated the role of estrogen receptors (ERs) in vitellogenesis (Vtgs) regulation in pompano fish. The findings suggest that E2 may regulate the expression of different subtypes of vtg through ERs, displaying a compensatory expression effect on the regulation of ers and vtgs. This provides a theoretical basis for further research on reproductive endocrinology in pompano fish.

Summary: Endocrine changes during bird reproduction, particularly the relationship between prolactin and incubation behavior, were investigated. The study monitored the physiological status and incubation behavior of Silkie hens over 1-2 years. The results showed that most mature hens exhibited incubation behavior multiple times, and there was a noticeable increase in nest occupancy 7-10 days before incubation onset. Protein analysis revealed that secreted prolactin during the reproductive cycle contains various isoforms, suggesting post-translational modifications like glycosylation and phosphorylation.

Summary: The COVID-19 pandemic had a significant impact on academics, particularly on those with minoritized identities or who were early career, caregivers, or had intersecting identities. The pandemic altered the impact factors of academia, including scholarly products, and affected the way individuals could respond. It is predicted that the pandemic will have long-term impacts on the population dynamics, composition, and landscape of the academic ecosystem. The number of journal submissions decreased, especially among women authors, and the pandemic heavily impacted women authors from Asia and the Middle East.
