This study observed that equine epididymis mainly expresses the type 1 isoform of 5α-reductase and effectively converts progesterone and testosterone to DHP and DHT, while finasteride and dutasteride inhibited this activity.

In a case study, a 6-year-old Shih Tzu with both demodicosis and babesiosis showed improvement after treatment, which included medications like ivermectin and supportive care such as specialized shampoos and environmental spraying, evaluated up to the 21st day.

This study found that deslorelin may promote hair regrowth in intact male dogs with hair cycle arrest, but had no effect on neutered females.

In this study, transitioning a dairy herd from a tie-stall to a free-stall barn improved the health of carpal and hock joints, but increased heel horn erosion and cortisol levels suggested heightened stress.

Skin hormone levels change significantly after menopause.

This study found that neurosteroids influence oxytocin secretion in sheep, particularly during stress and pregnancy, suggesting their role in protecting and maintaining pregnancy under harmful conditions.

In this study, a dog diagnosed with both ehrlichiosis and demodicosis showed significant clinical improvement after receiving a treatment regimen of doxycycline, ivermectin, diphenhydramine, vitamin B complex, and sulfur soap baths, noticeable by the 14th and 28th days of therapy.

This study found that women with PCOS displayed significantly higher activity of 5alpha-reductase, suggesting an additional role for liver and peripheral tissues in their androgen excess.

This study suggests that female hairless rats aged about 8 weeks offer the most consistent and reliable response in tests evaluating epidermal ornithine decarboxylase activity.

This study found that the combination of ethinylestradiol and desogestrel significantly decreased hair growth and hormone levels in hirsute women, suggesting a relationship between hormone changes and treatment effectiveness.

This study found no correlation between clinical signs and sex steroid levels in ferrets with hyperadrenocorticism and noted that androstenedione was elevated in many cases.

This study found that 5 alpha-dihydrotestosterone increased pigmentation in dorsal spots and scrotal skin of prepubertal male Syrian hamsters, while estradiol decreased scrotal skin melanocytes and reversed androgen-induced pigmentation in costovertebral spots.

In this study, two different estroprogestin treatments significantly improved skin conditions and decreased androgen levels in hyperandrogenic women, with EE/DRSP showing more pronounced hormonal changes and skin improvements compared to EE/CMA.

This study found that women with polycystic ovary syndrome have more pronounced metabolic alterations and higher androgen levels compared to women with eumenorrheic hyperandrogenism, suggesting EuHyperA may be a milder form of PCOS.

In this study, topical dehydroepiandrosterone (DHEA) doubled sebum production in women without systemic side effects, suggesting it may be a safe treatment for reduced sebum output related to menopause.

This study found that noninflammatory alopecia in dogs can be caused by exposure to estradiol gel used by their owners for postmenopausal symptoms, with hair regrowth observed after minimizing exposure.

In this study, chronic unpredictable stress affected male and female wild-derived house mice differently; stressed females gained less weight, had long grooming times, and lower immobility in tests, while stressed males showed increased hair corticosterone levels and shorter immobility times.

In this study, Diane was reported to effectively treat acne, seborrhoea, androgenic alopecia, and mild hirsutism in hirsute women, with its effectiveness influenced by the severity and duration of the condition.

This study observed that serum levels of oestradiol, testosterone, and androstenedione increase rapidly with the onset of puberty and continue to rise after menarche, with anovulatory cycles being common in early postmenarchal girls.

This study in female beagle dogs found that long-term exposure to oral contraceptive steroids resulted in significant reproductive and mammary gland changes, with the relevance to human tumor risk remaining uncertain.

This study found that women with PCOS have higher activity of the enzyme 5alpha-reductase, which may contribute to their elevated androgen levels.

This article discusses immunohistochemical analysis of estrogen and progesterone receptors in endometrium and peritoneal endometriosis, introducing a new quantitative method, but reports no new experimental results.

This meta-analysis found that while both Dienogest and GnRH analogues effectively managed endometriosis-related pain, Dienogest reduced recurrence rates and hot flushes but increased irregular bleeding, making it a safer option due to fewer side effects.

This study found that in mink, the pituitary gland is essential for normal seasonal pelage cycles, and manipulating hormone levels can affect hair growth and type.

This study found that canine demodicosis diagnosis is complicated by the absence of typical lesions and the presence of atypical symptoms like itching and generalized erythema, challenging traditional diagnostic approaches.
