Summary: Emerging evidence suggests that hormonal contraceptives impact psychological outcomes through alterations in neurophysiology. A synthesis of 46 studies (n = 16,290) found that HC users do not show the same menstrual cycle-related fluctuations in self-perceived attractiveness and some intrasexual competition seen in naturally-cycling women, and may have relatively reduced status- or achievement-oriented competitive motivation. However, there is a lack of consistent or compelling evidence that HC users and nonusers differ in competitive behavior or attitudes for mates or financial resources.

Summary: Oral contraceptives (OCs) are widely used and their potential effects on brain structure and function are being studied. Current research suggests that OCs may induce a hyperprogestogenic state in the brain.

Summary: By monitoring the concentrations of sex hormones and blood chemistry in female green turtles, it is possible to predict their nesting activity. This study found significant changes in hormone levels and blood chemistry parameters in relation to nesting activity. These findings can help predict and prepare for nesting activities in green sea turtles, contributing to successful breeding programs.

Summary: The study on female Indo-Pacific bottlenose dolphins in Ocean Park Hong Kong found that captivity dolphins reach puberty at 5 years and sexual maturity at 6. The serum concentrations of progesterone and estradiol were higher in sexually mature individuals compared to immature ones, with a bimodal pattern of progesterone levels during pregnancy. Serum testosterone concentrations were significantly elevated in a specific month compared to others.

Summary: This study examines the impact of childhood ecologies on people's sexual desire and finds that the unpredictability of childhood ecologies is positively associated with dyadic sexual desire among naturally cycling females. These findings suggest that the instability of early childhood ecologies can adaptively calibrate adult reproductive motivations and behaviors.

Summary: Based on the idea that women are attracted to ancestral markers of male genetic quality during their reproductive cycle, this study examines the moderating role of partner attractiveness on hormonal influences and women's extra-pair sexual interests. The findings suggest that partner attractiveness moderates the association between progesterone levels and women's extra-pair sexual interests.

Summary: This study comprehensively profiled the serum metabolome of participants using a combination of drospirenone (DRSP) and ethinyl estradiol (EE) containing oral contraceptives (COCs). The analysis revealed differences in metabolites between COC users and controls, suggesting a potential link to prothrombotic state and increased oxidative stress.

Summary: This study aimed to assess the association between endogenous steroid hormone levels and endometriosis. The results showed that women with higher levels of total estradiol during the early follicular phase had an increased risk of endometriosis. However, other hormone levels did not show a significant association with the risk of the disease.

Summary: This study investigated the relationship between steroid hormones and women's sexual attraction, and found no significant effect of steroid hormone levels on sexual attraction in naturally cycling women or women undergoing fertility treatment.

Summary: This study found that women's sexual desire and sexual activity frequency fluctuate during the menstrual cycle and are related to the hormones estradiol and progesterone. However, there is not a significant impact of these hormones on sexual arousal and initiation of sexual encounters.

Summary: The study aimed to determine if treatment with testosterone combined with nonestrogenic estrogen metabolites is sufficient for inducing a high incidence of prostate cancer in NBL rats. The results showed that long-term treatment with a nongenotoxic estrogen and testosterone, as well as uninhibited prostatic aromatase activity generating genotoxic estrogen, are all required for the development of prostate adenocarcinomas in NBL rats.

Summary: Myotis nigricans, a bat species endemic to the Neotropical region, plays an important ecological role in controlling nocturnal insects due to its insectivorous feeding habit and wide range of prey species. This study evaluated variations in serum hormone concentrations and uterine hormonal control in different reproductive phases of M. nigricans, showing that the uterus is strongly regulated by interactions between estradiol and progesterone. The expression of ER alpha and PR in the uterus appears synchronized to coordinate processes during pregnancy and lactation in this species.

Summary: This study investigated the changes in sexual hormones in dogs during puberty using hair and nail samples to analyze the concentrations of testosterone (T), 17 beta-estradiol (E2), and progesterone (P4). Traditional methods using blood samples are not suitable for long-term studies, but hair and nails have been identified as suitable retrospective biological specimens. The results showed significant increases in T levels in male dogs and E2 levels at puberty and P4 levels after puberty in female dogs. Hair and nail T and nail P4 concentrations could differentiate between male and female dogs at specific sampling times. This study demonstrates the usefulness of hair and nails as biological specimens for studying the changes in T, E2, and P4 during the peripubertal period in dogs.

Summary: The aim of this study was to investigate the applicability of several hormonal indexes for early prediction of puberty and reproductive state in pigs. The study showed an association between blood leptin, estradiol, progesterone, and IGF-I and future reproductive indexes.

Summary: The human voice is dynamic and people modulate their voices in various social interactions to exert dominance, display attractiveness, and signal competitiveness. Changes in voice can influence social perception, indicate certain qualities of the speaker, and serve as a medium for communication in relationships. Further research on vocal modulation will provide insights into its variation across social contexts and its impact on receiver psychology.

Summary: Sexual attraction to males or females is influenced by prenatal gonadal hormones, primarily through regulating gene expression in the developing brain. Androgens increase sexual attraction to females, while estrogens may increase sexual attraction to males. Polycystic ovary syndrome (PCOS), associated with elevated androgens, is more common in non-heterosexual females. The data regarding variation in sexual orientation among males is less clear, possibly due to distinct biological pathways.
