Hormone replacement therapy (HRT) increases the risk of endometrial and breast cancer. A strategy to reduce this incidence is the use of tibolone (TIB). The aim of this paper was to address the effects of TIB on the central nervous system (CNS). For the present review, MEDLINE (via PubMed), LILACS (via BIREME), Ovid Global Health, SCOPUS, Scielo, and PsycINFO (ProQuest Research Library) electronic databases were searched for the results of controlled clinical trials on peri- and postmenopausal women published from 1990 to September 2016...

Swainsonine is found in several plant species worldwide, and causes severe toxicosis in livestock grazing these plants, leading to a chronic condition characterized by weight loss, altered behavior, depression, decreased libido, infertility, and death. Swainsonine has been detected in 13 North American Astragalus species of which eight belong to taxa in four taxonomic sections, the Densifolii, Diphysi, Inflati, and Trichopodi. These sections belong to two larger groups representing several morphologically related species, the Pacific Piptolobi and the small-flowered Piptolobi...

BACKGROUND & AIMS: Even if patients with hemochromatosis maintain low serum levels of ferritin, they still have an increased risk of general and joint symptoms, which reduce quality of life. This could be related to persistently increased transferrin saturation. We assessed whether duration of exposure to increased transferrin saturation during maintenance therapy is associated with more severe general and joint symptoms. METHODS: We performed a longitudinal cohort study of 266 individuals homozygous for the C282Y substitution in HFE, seen at a tertiary reference center in Rennes, France, and followed for 3 or more years after initial iron removal...

Jean-Claude Soufir
Since the 1970s, international research on male contraception has been actively pursued. Hormonal and non-hormonal methods (thermal, chemical) have been tested, leading to clinical trials of interest to thousands of men and couples. The results showed that it was possible to develop methods of male contraception that inhibited spermatogenesis with good contraceptive efficacy. However, their side effects (mainly loss of libido), poorly accepted modes of administration, and the high frequency of poor responders prevented their widespread use...

INTRODUCTION: 30-40% of patients with Parkinson's disease (PD) experience depression during their illness; identifying subtypes of depression and groups at risk remains a challenge in routine clinical care. One avenue that remains underexplored is the gender-specific profiles manifested in PD depression. We sought to explore this in a large sample of clinical PD patients. METHODS: 307 patient records at a tertiary referral centre were reviewed for clinical and demographic factors...

The goal of testosterone replacement therapy (TRT) is to return serum testosterone levels to within physiologic range and improve symptoms in hypogonadal men. Some of the symptoms aimed to improve upon include decreased libido, erectile dysfunction, infertility, hot flashes, depressed mood, and loss of muscle mass or hair. Clinical use of testosterone for replacement therapy began approximately 70 years ago. Over the decades, numerous preparations and formulations have been developed primarily focusing on different routes of delivery and thus pharmacokinetics (PKs)...

We present a case report of an atypical giant pituitary adenoma secreting follicle-stimulating hormone (FSH). A 55-year-old patient presented for erectile dysfunction, loss of libido and fatigue. The biochemical evaluation showed very high FSH serum levels in the presence of central hypogonadism. Neither testicular enlargement nor increased sperm count was observed, thus a secretion of FSH with reduced biological activity was supposed. The histological examination after neuro-surgery showed an atypical pituitary adenoma with FSH-positive cells...

Sexual dysfunctions are commonly seen in women on selective serotonin reuptake inhibitors (SSRIs). The complexities of female sexual functioning are reflected through modulation of inter-playing factors like the neuropsychophysiological factors, inter-personal and relationship issue, psychiatric co-morbidities and physical disorder. The incidence of SSRIs-induced FSD is difficult to estimate because of the potentially confounding effects of SSRIs, presence of polypharmacy, marital effect, socio-cultural factors and due to the design and assessment problems in majority of the studies...

Testicular hypogonadism, or androgen deficiency, is defined as a clinical condition resulting from failure of the testes to produce physiologic levels of testosterone and a normal number of spermatozoa because of disruption of the hypothalamic-pituitary-gonadal axis. Testosterone deficiency (TD) is defined as a serum level less than 300 ng/dL on a morning total testosterone test. It is estimated that more than one-third of men 45 years and older have testosterone deficiency. Associated symptoms include decreased libido, erectile dysfunction, decreased physical stamina and strength, depressed mood, fatigue, increased visceral adiposity, sleep disturbance, and/or poor concentration and memory...
