330-360 / 1000+ resultsresearch 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 Stromal Cells of the Human Postmenopausal Ovary Display a Distinctive Biochemical and Molecular Phenotype
Postmenopausal ovary stromal cells have a unique makeup and limited steroid production, suggesting androgens come from the adrenal gland.
research HAIR COAT AND STEROIDAL IMPLANT EFFECTS ON STEERS GRA ZING NDOPHYTE-INFECTED TALL FESCUE DURING THE SUMMER
Steers with winter hair coats and reduced sweating struggled with heat, leading to less grazing and poor performance.
research Secondary amenorrhea
Secondary amenorrhea has many causes and requires thorough evaluation to treat and restore menstrual cycles.
research Key Aspects Of The Development Of The Menstrual And Ovarian Cycle In Adolescent Girls
Late onset of first period and irregular development of sexual traits in teenage girls can lead to poorer reproductive health.
research SEASONAL DERMATOPATHY AND CONCURRENT REPRODUCTIVE FINDINGS IN CAPTIVE FOSSA (CRYPTOPROCTA FEROX)
Hormonal changes during the reproductive cycle may cause seasonal skin problems in captive female fossas.
research Immunohistochemical analysis of estrogen and progesterone receptors in endometrium and peritoneal endometriosis: A new quantitative method
The new method showed that endometriotic tissue has lower estrogen receptor levels but similar progesterone levels compared to normal endometrium, with both following a similar cycle.
research Menstrual Disorders
The document concludes that common menstrual disorders affect adolescent women, with the normal menstrual cycle lasting 21 to 35 days.
research P131 Menstrual irregularity in hirsute women
Hirsute women with ovarian-sourced hirsutism are more likely to have irregular periods, with higher BMI and altered hormone ratios.
research The effect of a single epilation on successive hair eruptions in normal and hormone‐treated rats
Plucking hair speeds up the next hair growth, but hormones can change this timing.
research Kisspeptin and LH pulsatile temporal coupling in PCOS patients
Women with regular menstrual cycles and PCOS have linked kisspeptin and LH hormone patterns, unlike those with irregular cycles.
research Hormonal Control of Pelage Cycles In The Mink
The pituitary gland is crucial for normal mink fur cycles.
research Effects of progesterone (P4) and estrogen (E2) on fertilization failure and early embryonic mortality in superovulated cows
Hormonal treatments affect cow fertility and early embryo development.
research Hormonal control of pelage cycles in the short tailed weasel (Mustela erminea bangsi)
The pituitary gland controls seasonal fur color changes in weasels.
research Treating psychogenic nonepileptic seizures: Easier said than done
Progesterone treatment improved seizures in a woman with menstrual cycle-related epilepsy, but a wrong medication worsened her condition.
research Suety and Spreading-Stromal Hyperplasia and Hyperthecosis Ovary
These ovarian conditions cause high testosterone levels.
research Pharmacological Control of Reproduction in the Dog and Cat
Different drugs are used to manage breeding, prevent or end pregnancy, and treat reproductive issues in dogs and cats.
research 17β-Estradiol and ICI-182780 regulate the hair follicle cycle in mice through an estrogen receptor-α pathway
Estradiol stops hair growth in mice, but an antagonist can reverse this effect.
research Sex Hormones: Hormonal Contraception and Hormone Replacement Therapy
Hormonal contraceptives and therapies regulate organ functions and treat various conditions.
research Seasonal variation in hair follicle activity and fibre growth of both male and female Merghoz goats in Western Iran
Goat hair growth and follicle activity change with the seasons and differ between males and females.
research Progesterone, neurosteroids, and the hormonal basis of catamenial epilepsy
Progesterone and related compounds may help control seizures linked to the menstrual cycle but have limitations that need addressing.
research Androgens in female pig reproduction: actions mediated by the androgen receptor
Androgens may improve pig reproduction by enhancing ovulation and litter size.
research On the Effect of Estrogen Receptor Agonists and Antagonists on the Mouse Hair Follicle Cycle
β-estradiol slows hair growth in mice.
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 Assessing tolerability and physiological responses to 17α-estradiol administration in male rhesus macaques
research Effect of Neurosteroid Withdrawal on Spontaneous Recurrent Seizures in a Rat Model of Catamenial Epilepsy
Neurosteroid withdrawal increases seizure frequency in a rat model of catamenial epilepsy.
research [Ovulation inhibition in the treatment of androgenic alopecia in woemn].
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.
