Lowering 3α,5α-THP in the hippocampus increases anxiety and depression in proestrous rats.
research Cerebellar Changes in Guinea Pig Offspring Following Suppression of Neurosteroid Synthesis During Late Gestation
research The Effects of Perinatal Androgen Deprivation on Sexual Motivation in Male Rats
Blocking androgens at birth reduces sexual motivation in male rats.

research Menstrual Cycle Disturbances at Reproductive Age
Menstrual cycles can be irregular for women of childbearing age.
research DHT deficiency perturbs the integrity of the rat seminiferous epithelium by disrupting tight and adherens junctions
DHT deficiency can disrupt cell connections in rat testes, possibly affecting fertility.
research Androgen Profiling by Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS) in Healthy Normal-Weight Ovulatory and Anovulatory Late Adolescent and Young Women
The research found that anovulatory young women have higher androgen and hormone levels than those who ovulate, suggesting immature hormonal regulation rather than a specific condition.
research Effects of Flutamide, a pure antiandrogen, on endocrine parameters, in the adult female rat
Flutamide, an antiandrogen, has minimal impact on female rat endocrine systems and does not significantly change their reproductive cycles.
research Current evaluation of amenorrhea
Amenorrhea is when a woman doesn't have periods, with primary amenorrhea starting by age 15 or within five years of breast development, and secondary amenorrhea when periods stop for three months. It affects 3-4% of women not pregnant, breastfeeding, or in menopause, mainly due to polycystic ovary syndrome, hypothalamic amenorrhea, hyperprolactinemia, and ovarian failure.
research Estradiol‐induced alopecia in five dogs after contact with a transdermal gel used for the treatment of postmenopausal symptoms in women
Estradiol gel can cause hair loss in dogs.
research The Microanatomy, Cell Replication, and Keratin Gene Expression of Hair Follicles during a Photoperiod-lnduced Growth Cycle in Sheep
Changing light periods synchronized wool growth cycles in sheep.
research Dimorphic regulation of the MafB gene by sex steroids in hamsters (Mesocricetus auratus)
Sex steroids affect the MafB gene differently in male and female hamsters.
research Impact of One-Week Administration of Dihydrotestosterone in Rat Anterior Pituitary Gland
Dihydrotestosterone changes some hormone-related gene expressions in rat pituitary glands but doesn't affect the estrous cycle.
research Endocrine profile of the VCD-induced perimenopausal model rat
The rat model showed early perimenopause with regular cycles and low hormones, and late perimenopause with irregular cycles and higher hormone levels.
research Inhibitory influence of agmatine on catamenial-like seizure susceptibility in progesterone withdrawn female rats
Agmatine may help reduce seizures linked to hormone changes in female rats.
research Androgens stimulate specific aspects of maternal nest-building and reduce food intake in rabbits
Androgens boost certain nest-building behaviors and greatly reduce food intake in rabbits.
research Hyperandrogenic eumenorrheic NON-PCOS women versus women with PCOS after the GnRH-agonist stimulation test preceded by suppression of adrenal steroidogenesis with dexamethasone
PCOS women have more severe metabolic issues and higher androgen levels than hyperandrogenic women without PCOS.
research [Clinical findings with a low-dosed antiandrogene (cyproteronacetate) and aethinyloestradiol women with virilising symptoms (author's transl)].
The treatment improved acne, seborrhoea, and hirsutism, with some side effects like spotting and nervousness.
