PURPOSE: The goal of this study was to compare pregnancy outcomes between natural frozen embryo transfer (FET) cycles in ovulatory women and programmed FET cycles in anovulatory women after undergoing in vitro fertilization with preimplantation genetic screening (IVF-PGS). METHODS: This was a retrospective cohort study performed at an academic medical center. Patients undergoing single FET IVF-PGS cycles between October 2011 and December 2014 were included. Patients were stratified by type of endometrial replacement: programmed cycles with estrogen/progesterone replacement and natural cycles...

We describe a case of greater saphenous vein thrombosis in a 50-year-old previously healthy man, occurred only 3 weeks after starting testosterone (T) replacement therapy (20 mg/day, gel) for hypergonadotropic hypogonadism. There were no clinical known risk factors for thrombosis. Laboratory assessment of thrombophilia, performed later, revealed only methylenetetrahydrofolate reductase (MTHFR) A1298C polymorphism. On the basis of other recently reported cases, we suppose a relationship between androgenic therapy and venous thrombosis...

Since the June 2014 consensus statement published in Post Reproductive Health we have had definitive guidelines on menopause treatment from the National Institute for Clinical Excellence in November 2015. These included robust and evidence based information about many non-estrogen based treatments, which are particularly useful for patients who do not wish to take hormone replacement therapy, or who have medical contraindications to hormonal therapy such as hormone dependent cancers. Whilst none of these therapies is as effective as hormones, we must be able to advise patients about them and recommend which treatments may be helpful for individual women...

Transient receptor potential cation channel subfamily M member 8 (TRPM8) is associated with sensitivity to cold sensation in mammals. A previous study demonstrated that TRPM8 was overexpressed in the skin of ovariectomized (OVX) rats due to the loss of estrogen. In the present study, we investigated whether estrogen replacement restricts overexpression of the TRPM8 channel in the skin of OVX rats. We divided 15 Sprague Dawley rats into three groups: a non-operated group (NON-OPE), an ovariectomy group (OVX), and a group subjected to estrogen replacement during 4 weeks beginning 7 days after ovariectomy (OVX+E2)...

The 17 beta-estradiol (E2) is a sex hormone that is most abundant and most active estrogen in premenopausal women. The importance of E2 in providing cardioprotection and reducing the occurrence of heart disease in women of reproductive age has been well recognized. There are three subtype of estrogen receptors (ERs), including ERα, ERβ and GPR30 have been identified and accumulating evidence reveal their roles on E2-mediated genomic and nongenomic pathway in cardiomyocytes against various cardiac insults...

OBJECTIVE: Premature ovarian failure associated with Turner syndrome presents clinicians with a vast range of health concerns, including infertility, cardiovascular disease, and decreased bone mineral density, in addition to psychological sequelae. Hormone therapy is paramount in managing these complications, but the additional needs in the postpartum period for those who are able to carry out a successful pregnancy have not been described. METHODS: We present a case of severe postpartum depression (PPD) with psychotic features in a patient with Turner syndrome, which presented at 4 weeks after the birth of her first child via egg donation RESULTS:: We describe the case of a previously well 32-year-old patient with an 46 X, i(Xq) karyotype, who went through a 4-week intensive inpatient treatment course for PPD, requiring electroconvulsant therapy for persistent infanticidal and suicidal ideation...

Phytoestrogen has previously been proposed as an alternative to hormone replacement therapy. Hispolon has been found to have phytoestrogenic properties. However, the possible effects of hispolon on estrogen receptors and other related molecules remain to be determined. This study was performed mainly to confirm the estrogenic function of hispolon as it relates to estrogen receptors, aromatase, and cyclooxygenase 2 (COX-2). Hispolon was shown to increase the serum 17β-estradiol in vivo. Immunohistochemical staining methods showed that hispolon exhibited a biphasic effect on ERα/β and aromatase expression in MCF-7 cells...

INTRODUCTION: Sentinel lymph node biopsy (SLNB) is the reference standard for axillary staging in all patients with invasive breast cancer. Surgical practices are being reviewed for a more conservative approach to the axilla. PATIENTS AND METHODS: In this audit, we studied the incidence of axillary disease in patients with ultrasound negative axilla. The selection criteria are similar to an ongoing national study: female patients, age > 50 years, primary breast lesion < 1...

17α-Ethynylestradiol (EE2), a synthetic estrogen used in most oral contraceptives pills and hormone replacement therapies, is found in many water bodies, where it can modulate the fish immune response. EE2 acts as an endocrine disruptor in gilthead seabream, Sparus aurata L., a marine teleost fish of great economic value in Mediterranean aquaculture, as it induces hepatic vitellogenin gene (vtg) expression. Moreover, EE2 also alters the capacity of gilthead seabream to appropriately respond to infection although it does not behave as an immunosuppressor...

Gonadal steroids modulate CNS plasticity, including phrenic long-term facilitation (pLTF), a form of spinal respiratory neuroplasticity resulting in increased phrenic nerve motor output following exposure to acute intermittent hypoxia (aIH; three 5 min episodes, 10.5% O2). Despite the importance of respiratory system neuroplasticity, and its dependence on estrogen in males, little is known about pLTF expression or mechanisms of estrogen signaling in females. Here, we tested the hypotheses that: 1) pLTF expression in young, gonadally intact female rats would be expressed during estrous cycle stages in which 17β-estradiol (E2) is naturally high (e...

Plasticizers with estrogenic activity, such as bisphenol A (BPA), have potential adverse health effects in humans. Due to mounting evidence of these health effects, BPA is being phased out and replaced by other bisphenol variants in "BPA-free" products. We have compared estrogenic activity of BPA to 6 bisphenol analogues (bisphenol S, BPS; bisphenol F, BPF; bisphenol AP, BPAP; bisphenol AF, BPAF; bisphenol Z, BPZ; bisphenol B, BPB) in three human breast cancer cell lines. Estrogenicity was assessed (10-11M to 10-4M) by cell growth in an estrogen receptor (ER)-mediated cell proliferation assay, and by the induction of estrogen response element-mediated transcription in a luciferase assay...

Differentiated thyroid cancer (DTC) is markedly more common in women than men, the highest female-to-male ratio being recorded during the reproductive period. This evidence has led to the suggestion that female hormonal and reproductive factors may account for the observed DTC gender disparity. This review focuses on current evidence on the risk of DTC in conjunction with major female reproductive factors, including the impact of pregnancy on DTC occurrence and progression/recurrence. Overall, studies exploring the link between the risk of DTC and menstrual and menopausal factors, oral contraceptives and/or hormone replacement therapy, showed these associations, if any, to be generally weak...

Several studies show that a significantly stronger association is obvious between increased body mass index (BMI) and higher breast cancer incidence. Furthermore, obese women are at higher risk of all-cause and breast cancer specific mortality when compared to non-obese women with breast cancer. In this context, increased levels of estrogens due to excessive aromatization activity of the adipose tissue, overexpression of pro-inflammatory cytokines, insulin resistance, hyperactivation of insulin-like growth factors (IGFs) pathways, adipocyte-derived adipokines, hypercholesterolemia and excessive oxidative stress contribute to the development of breast cancer in obese women...

Clinical trials and studies have shown that combination estrogen/progestin hormone replacement therapy, but not estrogen therapy alone or placebo, increases breast cancer risk in postmenopausal women. Using animal models, we have previously shown that both natural and synthetic progestins (including medroxyprogesterone acetate [MPA], a synthetic progestin used widely in the clinical setting) accelerate the development of breast tumors in vivo and increase their metastasis to lymph nodes. Based on these observations, we have hypothesized that progestin-induced breast cancer tumor growth and metastasis may be mediated by an enrichment of the cancer stem cell (CSC) pool...

BACKGROUND & AIMS: Environmental factors have been identified that affect risk of hepatocellular carcinoma (HCC), but little is known about the effects of sex hormones on liver cancer development or outcome. We investigated whether menopause hormone therapy (MHT) affects risk, age at onset, or outcome of HCC. METHODS: We performed a case-control study of 234 female patients treated for HCC at a tertiary medical center and with 282 healthy women (controls), from January 1, 2004 through May 31, 2015...

Injury to the vertebrate brain causes neuroinflammation, characterized in part by increases in prostaglandins. In rodents and songbirds, brain injury also induces the transcription and translation of aromatase in reactive astrocytes around the site of damage. Interestingly, this induction is more rapid in female zebra finches relative to males. Induced aromatization is neuroprotective, as inhibition of aromatase and estrogen replacement, increases and decreases the extent of damage, respectively. While the consequences of induced astrocytic aromatization are intensely studied, little is known about what factor(s) induce aromatase...

Increased susceptibility to permeability transition pore (mPTP) is a significant concern to decreased cardiac performance in postmenopausal females. The goal of this study was to assess the effects of estrogen deficiency on the two spatially distinct mitochondrial subpopulations from left ventricle: subsarcolemmal mitochondria (SSM) and intermyofibrillar mitochondria (IFM) based on: morphology, membrane potential, oxidative phosphorylation, mPTP and reactive oxygen species production. Female rats (8weeks old) that underwent bilateral ovariectomy were randomly assigned to receive daily treatment with placebo (OVX), estrogen replacement (OVX+E2) and Sham for 60days...

Estrogen deprivation is associated with delayed healing, while estrogen replacement therapy (ERT) accelerates acute wound healing and protects against development of chronic wounds. However, current estrogenic molecules have undesired systemic effects, thus the aim of our studies is to generate new molecules for topic administration that are devoid of systemic effects. Following a preliminary study, the new 17β-estradiol derivatives 1 were synthesized. The estrogenic activity of these novel compounds was evaluated in vitro using the cell line ERE-Luc B17 stably transfected with an ERE-Luc reporter...

The role of gender in the progression of fatty liver due to chronic high-fat, high-fructose diet (HFFD) has not been studied. The present investigation assessed whether HFFD induced hepatic perturbations differently between genders and examined the potential mechanisms. Male, female and ovariectomized (OVX) Sprague-Dawley rats were fed either control diet or HFFD for 12 weeks. Indices of liver damage and hepatic steatosis were analyzed biochemically and histologically together with monitoring changes in hepatic gene and protein expression...

Adjuvant chemotherapy and anti-estrogenic therapy can result in decreased volume of the contralateral breast, following mastectomy for the treatment of breast cancer. However, no data on the effect of adjuvant therapy on contralateral breast volume have previously been reported. We aimed to evaluate the extent to which adjuvant therapy and differences in breast density contribute to decreased breast volume. We conducted a prospective cohort study, selecting 40 nonconsecutive patients who underwent immediate breast reconstruction with mastectomy and expander insertion followed by expander replacement...
