BACKGROUND: In previous work in young women aged 15-30 years we measured breast water and fat using MR and obtained blood for hormone assays on the same day in the follicular phase of the menstrual cycle. Only serum growth hormone levels and sex hormone binding globulin (SHBG) were significantly associated with percent breast water after adjustment for covariates. The sex hormones estradiol, progesterone and testosterone were not associated with percent water in the breast in the follicular phase of the menstrual cycle...

Hormone therapy (HT) is prescribed during or after menopausal transition to replace the decline in estrogen and progesterone levels. While some studies indicate that estrogen and progesterone depletion in postmenopausal women might carry a significant risk for developing sporadic Alzheimer's disease (sAD), which may be reduced by HT, recent clinical trials oppose this beneficial effect. This review points to possible reasons for these mixed data by considering the issues of both preclinical and clinical trials, in particular, the representativeness of animal models, timing of HT initiation, type of HT (different types of estrogen compounds, estrogen monotherapy vs...

: Studies of the effect of hormone therapy on cognitive function in menopausal women have been equivocal, in part due to differences in the type and timing of hormone treatment. Here we cognitively tested aged female rhesus macaques on (1) the delayed response task of spatial working memory, (2) a visuospatial attention task that measured spatially and temporally cued reaction times, and (3) a simple reaction time task as a control for motor speed. After task acquisition, animals were ovariectomized (OVX)...

In sheep, embryonic and fetal death during pregnancy can account for 25% to 50% of the total number of corpora lutea (and thus potential embryos). The objective of this study was to determine the effects of injectable and oral Arg supplementation provided for 14 d postbreeding on the reproductive performance of naturally stimulated fall lambing ewes. Rambouillet ewes ( = 210) were exposed to rams equipped with marking harnesses to induce cyclicity in April 2012. Upon estrus detection (d 0) ewes were randomly assigned, in a completely random design, to 1 of 6 treatments for a 14-d treatment period: injectable saline (CON; = 25), injectable Ala (IVALA; = 20), injectable Arg (IVARG; = 23), oral rumen-protected Arg (RPARG; = 20), oral fish meal (FM; = 24), or oral soybean meal (SBM; = 23)...

CONTEXT: Classic congenital adrenal hyperplasia (CAH) management remains challenging, as supraphysiologic glucocorticoid doses are often needed to optimally suppress the ACTH-driven adrenal androgen overproduction. OBJECTIVE: To approximate physiologic cortisol secretion via continuous subcutaneous hydrocortisone infusion (CSHI) and evaluate the safety and efficacy of CSHI in difficult-to-treat CAH patients. DESIGN: Eight adult patients with classic CAH participated in a single-center open label phase I-II study comparing CSHI to conventional oral glucocorticoid treatment...

Progesterone is an essential hormone in the process of reproduction. It is involved in the menstrual cycle, implantation and is essential for pregnancy maintenance. It has been proposed and extensively used in the treatment of different gynecological pathologies as well as in assisted reproductive technologies and in the maintenance of pregnancy. Called "the pregnancy hormone", natural progesterone is essential before pregnancy and has a crucial role in its maintenance based on different mechanisms such as: modulation of maternal immune response and suppression of inflammatory response (the presence of progesterone and its interaction with progesterone receptors at the decidua level appears to play a major role in the maternal defense strategy), reduction of uterine contractility (adequate progesterone concentrations in myometrium are able to counteract prostaglandin stimulatory activity as well as oxytocin), improvement of utero-placental circulation and luteal phase support (it has been demonstrated that progesterone may promote the invasion of extravillous trophoblasts to the decidua by inhibiting apoptosis of extravillous trophoblasts)...

Postpartum effluvium is a well-known clinical fact. However, following some minor research activities in the 1960s, very little has happened on the research front of the subject. It was hypothesized that postpartum hair loss might be a manifestation of a change in the hair growth cycle occurring normally during pregnancy. Recently, new research has been published trying to explain the mechanism of action behind this frequently occurring hair growth disruption, and to develop a functional treatment schedule and regime...

The influence of contraception on vaginal microflora can have a major impact on the risk of developing acute or recurrent vaginal infections, but also may influence the risk of acquiring sexually transmissible infections (STI) such as HIV. A cohort of 248 women presenting for levonorgestrel-releasing intrauterine system (LNG-IUS) insertion or reinsertion were stratified according to their current contraceptive method. Information concerning their menstrual pattern and data about the medical history were collected...

INTRODUCTION: Treatment of ovarian endometriomas is commonly achieved through laparoscopic surgery and this can be effective in eliminating the disease, although a majority of recent trials documented an adverse effect of surgery on ovarian reserve markers. With the advancement in imaging techniques, ovarian endometriomas are increasingly diagnosed at an earlier stage when the endometrioma may be smaller, less fibrotic and more responsive to medical treatment, making an evaluation of medical options critically important...

In human immunodeficiency virus type 1 (HIV-1)-infected women, oral or injectable progesterone containing contraceptive pills may enhance HIV-1 acquisition in vivo, and the mechanism by which this occurs is not fully understood. In developing countries, Herpes simplex virus type-2 (HSV-2) co-infection has been shown to be a risk for increase of HIV-1 acquisition and, if co-infected women use progesterone pills, infections may increase several fold. In this study, we used an in vitro cell culture system to study the effects of progesterone on HIV-1 replication and to explore the molecular mechanism of progesterone effects on infected cells...

In women, progesterone suppresses luteinizing hormone (LH) (gonadotropin-releasing hormone) pulse frequency, but how rapidly this occurs is unknown. In estradiol-pretreated women in the late follicular phase, progesterone administration at 1800 did not slow sleep-associated LH pulse frequency. However, mechanisms controlling LH pulse frequency may differ according to sleep status; and we thus hypothesized that progesterone acutely suppresses waking LH pulse frequency. This was a randomized, double-blind, crossover study of LH secretory responses to progesterone versus placebo administered at 0600...

Primary mucinous adenocarcinomas of the salivary gland are rare malignancies defined by aggregates of epithelial cells suspended in large pools of extracellular mucin. We report a case of a giant mucinous adenocarcinoma of salivary gland origin, with low-grade cytoarchitectural features and neuroendocrine differentiation arising in the submental region. Grossly, the tumor measured 12.5 × 13.4 × 8.2 cm and replaced the bone and soft tissues of the anterior oral cavity. Microscopically, the neoplasm was composed of large extracellular pools of mucin, which contained papillary and acinar aggregates, and small nodules of ductal type epithelium with minimal nuclear enlargement, powdery chromatin and little pleomorphism...

This systematic review focuses on the literature evidence for residual ovarian function during treatment with hormonal contraceptives. We reviewed all papers which assessed residual ovarian activity during hormonal contraceptive use, using endocrine markers such as serum anti-Müllerian hormone (AMH) concentrations, FSH, LH, oestradiol, progesterone and sonographic markers such as antral follicle count (AFC), ovarian volume and vascular indices. We considered every type (oestroprogestin or only progestin) and dosage of hormonal contraceptive and every mode of administration (oral, vaginal ring, implant, transdermal patch)...

Autoimmune progesterone dermatitis (APD) is a rare skin condition with a varying morphology, which appears on a monthly basis during the luteal phase of the menstrual cycle and resolves spontaneously with the endogenous decrease in progesterone during menses. We present the case of 39-year-old multiparous Caucasian woman with generalised, self-limited urticaria in her perimenstrual period. APD was diagnosed in light of the cyclical nature of the symptoms. An intradermal test with the administration of 0.5 mg/mL of medroxyprogesterone acetate showed a positive result...

BACKGROUND: Recent studies have shown an increase in the incidence of oral squamous cell carcinoma (OSCC) in younger patients. The hypothesis that tumors could be hormonally induced during pregnancy or in young female patients without the well-known risk factors alcohol or tobacco abuse seems to be plausible. MATERIAL AND METHODS: Estrogen Receptor alpha (ERα) and Progesterone Receptor (PR) expression were analyzed in normal oral mucosa (n=5), oral precursor lesions (simple hyperplasia, n=11; squamous intraepithelial neoplasia, SIN I-III, n=35), and OSCC specimen...
