research Short communication: Temporal changes in the skin morphology of dairy cows during the periparturient period

Hormonal changes during the reproductive cycle may cause seasonal skin problems in captive female fossas.
research Problems in evaluating chronic toxicity of contraceptive steroids in dogs
High doses of some contraceptive steroids cause health issues in dogs, but their relevance to humans is unclear.
research Clinical symptoms and sex steroid measurements in domestic ferrets (Mustela putorius furo) with hyperadrenocorticism
Neutered ferrets often develop hyperadrenocorticism, with symptoms like hair loss and lethargy, and androstenedione is a key indicator for diagnosis.
research Steroid 17β-hydroxysteroid dehydrogenase deficiency in man: An inherited form of male pseudohermaphroditism
Affected males are born with ambiguous genitalia, raised as females, but develop male traits at puberty due to enzyme deficiency.
research Ovine placental steroid synthesis and metabolism in late gestation†
Diet changes hormone levels in pregnant ewes by affecting metabolism, not placental synthesis.
research Change in Hair Cycle and Hair Length in Nude Mice by Administration of Deuterium Oxide
Deuterium oxide extends the hair cycle duration in mice without changing hair structure.
research Ultra-low dose estradiol and dydrogesterone for the treatment of menopausal symptoms in a pooled, multi-ethnic population
The treatment effectively reduces menopausal symptoms and is well tolerated.
research Cutaneous hydroxystereoid dehydrogenases and rat-hair-cycle
Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.
research Equine 5α-reductase activity and expression in epididymis
The equine epididymis mainly uses type 1 5α-reductase, and both finasteride and dutasteride can inhibit its activity.
research Estrogens
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 The biochemical and phenotypic characterization of females homozygous for 5 alpha-reductase-2 deficiency.
Females with 5 alpha-reductase-2 deficiency have less body hair, no acne, normal fertility, and delayed menarche.
research Hormonal Control of Pelage Cycles In The Mink
The pituitary gland is crucial for normal mink fur cycles.
research [Changes in claw and leg health and hair cortisol concentration in dairy cows during the transition from tie-stall to free-stall housing - A study of a medium-sized farm].
