OBJECTIVES Since sex hormone markers are metabolically linked, examining sex steroid hormones singly may account for inconsistent findings by age, race/ethnicity and body mass index (BMI) across studies. First, these markers were statistically combined into profiles to account for the metabolic relationship between markers. Then, the relationships between sex steroid hormone profiles and age, r...

objective: to evaluate the relationship between serum level of testosterone and sex hormone-binding globulin in men with type 2 diabetes. materials and methods: in this case-control study, forty men aged 40-70 with type 2 diabetes mellitus were randomly selected and compared with 40 non-diabetic men. the two groups were matched for their age and bmi. after complete observation and examination, ...

There is a close relationship between the brain and the endocrine system. The brain expresses receptors for sex steroids and is capable of metabolizing these hormones. We explored (1) sex differences in homovanillic acid (HVA), a metabolite of the neurotransmitter dopamine, and (2) the effects of cross-sex steroid administration in transsexual subjects. First, we compared plasma HVA levels betw...

Variations in the hormonal milieu after menopause may influence neural processes concerned with cognition, cognitive aging, and mood, but findings are inconsistent. In particular, cognitive effects of estradiol may vary with time since menopause, but this prediction has not been assessed directly using serum hormone concentrations. We studied 643 healthy postmenopausal women not using hormone t...

Meningiomas have often been described as being hormone dependent because of their preponderant incidence in females with clinical manifestation during or after pregnancy. The authors have experienced three cases of meningioma which became symptomatic during pregnancy, after delivery, or during menses. Estrogen receptor protein and progesterone receptor protein of the meningioma tissue were exam...

Background: Multiple sclerosis (MS) is the most common cause of progressive neurological disability in young adults who may be sexually active. MS patients experience high levels of sexual dysfunction with hypoactive sexual behavior and abnormalities in hypothalamus- pituitary-gonad (HPG) axis. In the present study, we aimed to evaluate the correlation between serum levels of sex hormones durin...

Sex expression in cucumber is influenced by hormonal and environmental factors such as day length and temperature. Increasing female flowers that will develop to fruit is a trick for increasing yield, hence it’s importance. Likewise, it would help breeders through hybridizing process. Ethylene as a plant hormone is known to increase female flowers of most members of Cucurbitaceae family but as ...

Decline in circulating sex steroid hormones accompanies several age-associated pathologies which may influence human healthspan. Mitochondria play important roles in biosynthesis of sex steroid hormones, and these hormones can also regulate mitochondrial function. Understanding the cross talk between mitochondria and sex steroid hormones may provide insights into the pathologies associated with...

BACKGROUND Sex-related differences in the severity of multiple sclerosis (MS) could be influenced by the sex hormones. MATERIALS AND METHODS This cohort (historical) study evaluated the sex hormone levels during menstrual cycle and their correlation with disease severity in MS. RESULT Patients with MS had significantly lower testosterone, dehydroepiandrosterone sulfate and prolactin levels ...
