Progestins used in endocrine therapies bind to multiple steroid receptors and are associated with several side-effects. It is thus important to understand the relationship between steroid receptor cross-reactivity and the side-effect profile of progestins. In cell lines that express negligible levels of steroid receptors, we report for the first time the binding affinities, potencies and efficacies of selected progestins from different generations determined in parallel. We show that the progestins bind to the androgen receptor (AR) with similar affinities to each other and progesterone, while none bind estrogen receptor (ER)-β, and only norethisterone acetate, levonorgestrel and gestodene bind ERα...

Uterine leiomyomas have drawn much attention since being described more than 200 years ago. These common benign uterine tumors often present with prolonged menstrual bleeding, pelvic pressure, and reproductive disorders and pose a true financial burden on health care systems all over the world. Over the past few decades, surgical treatment of uterine leiomyomas has received most of the focus compared with other treatment options. Choosing the appropriate surgical technique depends on many factors such as uterine leiomyoma location, patient's age, interest in future fertility, concomitant comorbidities, and the patient's preference...

Progesterone shows anti-inflammatory and promyelinating effects in mice with autoimmune experimental encephalomyelitis (EAE), a commonly used model for multiple sclerosis (MS). Since neurosteroids have been implicated as protective factors for MS and EAE, we analyzed the expression of neurosteroidogenic enzymes in the compromised spinal cord of EAE mice. EAE was induced in female C57Bl6 mice and killed on day 16 after induction. Progesterone was given by pellet implantation 1 week before EAE induction. Untreated EAE mice showed decreased mRNAs for the steroidogenic acute regulatory protein (Star), voltage-dependent anion channel (VDAC), cholesterol side-chain cleavage (P450scc), 5α-reductase, 3α-hydroxysteroid dehydrogenase (3α-HSOR) and aromatase, whereas changes of 3β-hydroxysteroid dehydrogenase (3β-HSD) were not significant...

BACKGROUND: While progesterone affects sleep, different types of it might affect sleep differently. METHODS: One hundred Thai women, who complained of insomnia, visited the Menopause Clinic at Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand from February 2014 to March 2015, and were divided randomly into two groups. Both groups received daily hormonal treatment that included estradiol valerate (progynova) at 1 mg. The first group also received dydrogesterone (duphaston(®)) at 10 mg and the second group micronized progesterone (utrogestran(®)) at 100 mg...

BACKGROUND: Despite the widespread use of dexamethasone in veterinary and human medicine, it is reported to cause some severe pregnancy related side effects like abortion in some animals. The mechanism of the response is not clear but seems to be related to interspecies and/or breed difference in response which may involve alterations in the concentrations of some reproductive hormones. METHODS: Twenty Sahel goats comprising 18 does and 2 bucks were used for this study...

Views and clinical practice on hormone replacement therapy (HRT) for postmenopausal women have varied widely over the last several decades. The 1990s showed a dramatic decline in prescribing and only recently are prescription rates increasing again. Use of HRT is first line for women suffering from the symptoms of menopause. For a certain population of postmenopausal women, HRT is recommended for prevention of fracture. More consideration is being given to patient risk factors, side effects, and formulations available...

In view of the small number of recurrent and metastatic cases of female adnexal tumors of probable Wolffian origin (FATWO), there is a distinct lack of evidence to support recommendations regarding treatment. In the present study, a 37-year-old female was diagnosed with a left adnexal tumor and underwent a left salpingo-oophorectomy (SO). The tumor was found to arise from the left tubal fimbria and extend to the posterior leaf of the broad ligament. Pathological examination identified a number of solid, tubular and cystic architectures, with areas of hyalinization, hemorrhage and necrosis...

This was an observational study investigating the efficacy and side effects associated with ulipristal acetate (UPA), a progesterone receptor modulator, and the possible benefits to women who have co-existing pre-menstrual syndrome (PMS). 80 women returned a questionnaire on the bleeding, menstrual pain and side effects, and changes on PMS were recorded. 67 women (84%) showed improvement in their menses. 54 women (67%) became amenorrhoeic. Of those, 67% were within 10 days of commencing UPA. Menses returned in 33 amenorrhoeic women within 4 weeks of stopping UPA...

Triple-negative breast cancer is a highly aggressive type of mammalian carcinoma. It is defined by a rather weak expression of estrogen-, progesterone- and Her2-receptor, and is thus difficult to treat, resulting in low disease-free and overall survival rates of the affected patients. Hence it is important to find new therapeutic options. To this aim we analysed the incidence of some molecules from different signal transduction cascades by immunohistochemistry, which are known to correlate with triple-negative breast cancer, and correlated the expression of these molecules to different tumour traits, such as size, grading, menopausal stage, histology, lymph node affection, remote metastasis formation, and to the incidence of local and lymph node recurrence and metastasis by statistical analysis...

We have earlier reported the presence of very small embryonic-like stem cells (VSELs) in adult mouse uterus along with slightly bigger progenitors termed endometrial stem cells (EnSCs) and their regulation by ovarian hormones thus demonstrating a crucial role played by them during proliferation, differentiation and remodeling of the endometrium. Present study is a brief communication wherein we have examined the effect of higher dose of estrogen (E, 2 μg/day), progesterone (P, 1 mg/day) and follicle stimulating hormone (FSH, 5 IU/day for 5 days) specifically on the myometrium and perimetrium surrounding the endometrium in bilaterally ovariectomized mice...

Endocrine disruption caused by various anthropogenic compounds is of persisting concern, especially for aquatic wildlife, because surface waters are the main sink of these so-called endocrine disruptors (ED). In the past, research focused on (anti)estrogenic, (anti)androgenic, and (anti)thyroidal substances, affecting primarily reproduction and development in vertebrates; however, other endocrine systems might be also targeted by ED. Environmental gestagens, including natural progestogens (e.g. progesterone (P4)) and synthetic progestins used for contraception, are supposed to affect vertebrate reproduction via progesterone receptors...

Recent reports show that, in patients treated with finasteride for male pattern hair loss, persistent side effects including sexual side effects, depression, anxiety and cognitive complaints may occur. We here explored the psychiatric and andrological features of patients affected by post-finasteride syndrome (PFS) and verified whether the cerebrospinal fluid (CSF) and plasma levels of neuroactive steroids (i.e., important regulators of nervous function) are modified. We found that eight out of sixteen PFS male patients considered suffered from a DSM-IV major depressive disorder (MDD)...

PURPOSE AND OBJECTIVE: Endometriosis is a gynaecological disease that is characterised by the presence of endometrium like tissue-epithelium and stroma that develops outside the uterine cavity, which is responsible for pelvic pain and infertility. Even though several medical therapies exist for the treatment of endometriosis, each of the drug class has its own limitations such as cost of treatment, side-effects and its short-term effect on the symptoms of endometriosis. In this review, we have attempted to summarize the current status and challenges of drug development for endometriosis...

Background: Compelling evidence shows that progestins regulate breast cancer growth. Using preclinical models, we demonstrated that antiprogestins are inhibitory when the level of progesterone receptor isoform A (PR-A) is higher than that of isoform B (PR-B) and that they might stimulate growth when PR-B is predominant. The aims of this study were to investigate ex vivo responses to mifepristone (MFP) in breast carcinomas with different PR isoform ratios and to examine their clinical and molecular characteristics...

Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder of women of reproductive age characterized by polycystic ovarian morphology, anovulation or oligomenorrhea, and hyperandrogenism. It is shown that disruption in the steroidogenesis pathway caused by excess androgen in PCOS is a critical element of abnormal folliculogenesis and failure in dominant follicle selection. Vitamin D plays an important role in the regulation of ovulatory dysfunction and can influence genes involved in steroidogenesis in granulosa cells...

Finasteride is currently used extensively for male androgenic alopecia and benign prostatic hyperplasia; however, some adverse effects are severe and even persistent after treatment cessation, the so-called 'post-finasteride syndrome'. The following most severe adverse effects-sexual dysfunction and depression-often occur together and may potentiate one other, a fact that could explain (at least in part) the magnitude and persistence of finasteride adverse effects. This paper presents the pharmacological action of finasteride and the corresponding adverse effects, the biological base explaining the occurrence, persistence and distribution of these adverse effects, and a possible therapeutic solution for post-finasteride syndrome...

Endometriosis affects 1 in 10 women of reproductive-age. The current treatments are surgical and hormonal but have limitations, including the risk of recurrence, side effects, contraceptive action for women who desire pregnancy, and cost. New treatments include gonadotropin-releasing hormone analogues, selective progesterone (or estrogen) receptor modulators, aromatase inhibitors, immunomodulators, and antiangiogenic agents. Further research is needed into central sensitization, local neurogenesis, and the genetics of endometriosis to identify additional treatment targets...
