Selective progesterone receptor modulators for the treatment of dysmenorrhea: an update.

Introduction: Dysmenorrhea is a painful symptom associated with uterine contractions and menstrual bleeding and is treated by administering analgesic drugs. Since progesterone receptors (PRs) have a major role in regulating uterine tissues (myometrium and endometrium) oral contraceptives are used off-label for treating primary or secondary dysmenorrhea. The development of selective progesterone receptor modulators (SPRMs) a class of synthetic steroids with agonistic, antagonistic, or mixed effects in targeting PRs in different tissues stimulated their possible clinical use for treating secondary dysmenorrhea related to uterine diseases (endometriosis, adenomyosis, uterine fibroids).

Women may be challenged to maintain thermoregulation due to hormonal changes associated with the menstrual cycle. The purpose of this study was to assess the effect of the menstrual cycle phase on core temperature, hydration status, and perceived exertion while exercising under uncompensable heat gain. Eleven eumenorrheic women (24.

Objective: The effects of sex hormones remain largely unexplored in pheochromocytomas and paragangliomas (PPGLs) and gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
Methods: We evaluated the effects of estradiol, progesterone, Dehydroepiandrosterone sulfate (DHEAS), and testosterone on human patient-derived PPGL/GEP-NET primary culture cell viability (n = 38/n = 12), performed next-generation sequencing and immunohistochemical hormone receptor analysis in patient-derived PPGL tumor tissues (n = 36).
Results: In PPGLs, estradiol and progesterone (1 µm) demonstrated overall significant antitumor effects with the strongest efficacy in PPGLs with NF1 (cluster 2) pathogenic variants.

Affective, behavioral, and cognitive (i.e., personality) states fluctuate across situations and context, yet the biological mechanisms regulating them remain unclear.

This study investigated the association of menstrual cycle phase and symptoms with objective and subjective sleep measures from professional footballers before and after matches. Twenty-three non-hormonal contraceptive-using professional footballers (from four clubs) were monitored for up to four menstrual cycles during a domestic league season. Menstrual phases (menstruation, mid-late follicular, luteal) were determined using calendar counting and urinary hormone tests (luteinizing hormone and pregnandiol-3-glucuronide).
