The objective of this cross-sectional study was to determine the relationship between hyperandrogenemia and blood pressure in women with menstrual irregularities seen at an endocrinology clinic. Women with serum testosterone levels (T) > or = 30 ng/dL were more likely to have general obesity (odds ratio [OR] = 6.8, 95% confidence intervals [CI] = 2.2-27.2) and central obesity (OR = 14.5, 95% CI = 6.1-38.7) than euandrogenemic women. Hyperandrogenemic women (HA) had an OR of 2.4 (95% CI = 1.0-6.2) for elevated SBP and an OR of 2.7 (95% CI = 0.8-8.8) for elevated DBP, independent of age and ovulatory status. Obese HA had an OR of 4.7 (95% CI = 2.3-10.4) for elevated SBP and an OR of 2.9 (95% CI = 1.9-9.9) for elevated DBP. In conclusion, T is associated with an increased risk for obesity and central adiposity. T predicts BP elevation independent of age and ovulatory status. There was a synergistic relationship between obesity and androgens in their affect on BP.

Background: Good knowledge about the ovulatory cycle plays an important role in reducing unwanted pregnancies and unsafe abortions among adolescent females. However, in Ghana, knowledge of the ovulatory cycle among adolescent females is not well studied. Thus, this study sought to assess adolescent females' knowledge regarding the ovulatory cycle and its determinants in Ghana.

Study Question: Do polycystic ovary syndrome (PCOS), menstrual cycle phases, and ovulatory status affect reproductive tract (RT) microbiome profiles?
Summary Answer: We identified microbial features associated with menstrual cycle phases in the upper and lower RT microbiome, but only two specific differences in the upper RT according to PCOS status.
What Is Known Already: The vaginal and uterine microbiome profiles vary throughout the menstrual cycle. Studies have reported alterations in the vaginal microbiome among women diagnosed with PCOS.

Female reproduction is highly sensitive to body energy stores; persistent energy deficit, as seen in anorexia or strenuous exercise, is known to suppress ovulation via ill-defined mechanisms. We report herein that hypothalamic SIRT1, a key component of the epigenetic machinery that links nutritional status and puberty onset via modulation of Kiss1, plays a critical role in the control of the preovulatory surge of gonadotropins, i.e.

The main objectives of the present study were to determine the effects of presynchronizing with a 1.0 g intravaginal progesterone device (IVPD) and prostaglandin F2α and to assess the effects of re-utilization of IVPD in a 2x2 factorial design, on the ovulatory response to first GnRH, ovarian status at different protocol stages, estrus expression and fertility in beef heifers submitted to a 5d-CO-Synch + Progesterone (P4) protocol. Beef heifers (n = 564) were assigned to 1 of 2 treatments at D-15: Pres5 (n = 283), where heifers received a (IVPD) for 5 days and administration of prostaglandin F2α (25 mg of dinoprost) at D-10; and Control (n = 281), where heifers received no treatment.

Treatment with intra-vaginal progesterone pessaries for synchrony of estrus is essential in fixed-time artificial insemination (AI) of sheep. Globally, the conventional 14-day pessary treatment is the mainstay of commercial AI programs. It has remained largely unchanged for many decades even though it is associated with variable patterns of estrus and often disappointing pregnancy rates.
