This study found that a blackcurrant extract with phytoestrogen activity increased hair number and stem cell marker expression in a menopausal rat model, suggesting a potential benefit for hair loss.

This study found that administering testosterone to ovariectomized female rats decreased endometrial tight junction complexity and expression of specific proteins, potentially affecting embryo implantation.

This study found that testosterone increased the expression of AQP-1, 5, and 7 in the uterus of rats, which may help explain the reduction in uterine fluid volume.

This article reviews studies on thyroid influence on hair growth, noting varied results, including accelerated growth in some normal and underfed rats after thyroid administration, but reports no clinical results.

In this study, perinatal androgen deprivation in male rats led to elevated estrogen levels and a lack of sexual motivation towards gonadally-intact female rats.

This study reports that TFM-4AS-1, a selective androgen receptor modulator, promoted bone and muscle growth with reduced effects on reproductive organs in ovariectomized rats.

This study found that testosterone administration reduced the expression of uterine receptivity molecules in ovariectomized rats, which may negatively affect early pregnancy establishment and female fertility.

The researchers reported that metabolism of progesterone to 3α,5α-THP in the hippocampus is important for its antiseizure effects in ovariectomized rats.

This study found that ovariectomized and finasteride-treated rats showed significant tear film deficiency and downregulation of sex steroid receptors in ocular tissues, suggesting potential models for studying dry eye disorders.

In this study, Ishige sinicola extract was observed to improve bone density and structure in an animal model of estrogen deficiency-induced osteoporosis, suggesting its potential as a therapeutic option for postmenopausal osteoporosis by inhibiting osteoclast formation without cytotoxic effects.

This study found that blocking androgen receptors in male rats during the perinatal period led to permanently increased estrogen and ER-a expression in the hypothalamus, affecting sexual preference in adulthood.

This study found that a complex extract of Polygonatum sibiricum and Nelumbinis semen improved menopause symptoms in an ovariectomized rat model by enhancing blood lipid metabolism and reducing osteoporosis, without increasing risks of side effects like endometriosis, unlike conventional hormone-replacement therapy.

In this study, treatment with DHEA induced mild to moderate hyperplasia of sebaceous glands in ovariectomized rats, which was prevented by the antiandrogen Flutamide but not by the antiestrogen EM-800.

This study found that progesterone can inhibit spinal reflex potentiation in ovariectomized rats through GABA(A) receptor activity, mediated by neurosteroid metabolism rather than direct progesterone receptor action.

The study observed that testosterone reduced knee range of motion in ovariectomized female rats, potentially by downregulating specific relaxin receptor isoforms, with its effects mediated via dihydro-testosterone.

This study demonstrates that young coconut juice appears to have estrogen-like properties that can accelerate wound healing in ovariectomized rats.

This study reports that progesterone metabolism to DHP and THP is necessary for its neuroprotective effect against kainic acid excitotoxicity in ovariectomized rats, unlike the synthetic progestin MPA.

This study found that cryptotanshinone improved bone mass, inhibited osteoclast differentiation, and protected against kidney damage in ovariectomized rats, suggesting potential benefits for clinical use.

This study suggests that testosterone may reduce knee joint range of motion by acting on relaxin receptors in rats, while flutamide and finasteride counteracted this effect and increased receptor expression.

Allopregnanolone, a progesterone metabolite, helps reduce restraint effects on behavior.

This study describes the enzymatic processes through which DHEA is converted to active sex steroids in human skin, highlighting an androgenic effect on sebaceous glands and estrogenic effects in the vagina.

This study observed that electro-acupuncture reduced global DNA methylation and DNMT3b expression in a PCOS-like rat model, suggesting a role of hypothalamic DNA methylation in PCOS development and treatment.

In this study, finasteride treatment did not negatively impact bone development or density in male rats, suggesting that DHT deficiency is not harmful to the male rat skeleton.

Finasteride blocks deoxycorticosterone's anticonvulsant effects in infant rats, but indomethacin doesn't.

This study concluded that finasteride treatment did not adversely affect bone development or density in male rats, suggesting selective DHT deficiency is not harmful to the skeleton.

This study found that repeated finasteride administration in male Wistar rats led to increased depression-like behavior, suggesting an animal model for investigating finasteride's neuropsychiatric effects is viable.

This study found that a week of daily alcohol exposure during late adolescence led to a long-term increase in alcohol preference in adulthood, highlighting the sensitivity of this age group to alcohol's effects.

This study found that testosterone replacement in castrated male rats counteracted endotoxemia-induced arterial baroreflex dysfunction without significantly affecting neuroinflammation.

Finasteride slows down motherly behavior in first-time pregnant rats.

In this study, the aqueous extract from Phthirusa pyrifolia leaves significantly decreased testosterone levels in male Wistar rats without causing liver or kidney damage, suggesting potential effects on libido and reproduction.
