30-60 / 1000+ resultsresearch A case report of a novel homozygote mutation causing severe Leydig cell hypoplasia: insights in the coexistence of nonsense mutation and polymorphism in the same LHCGR gene locus
A new genetic mutation causes severe Leydig cell hypoplasia, affecting sexual development.
research Endocrinology Overview RSS
The document explains how male reproductive hormones work and affect the body.
research Reproductive System, Male
The document explains how sperm cells are produced, the role of testosterone in this process, and how toxins can reduce sperm count and fertility.
research Infertility in Polycystic Ovary Syndrome: Focus on Low-Dose Gonadotropin Treatment
Low-dose gonadotropin treatment is effective for infertility in women with PCOS, leading to high ovulation rates and comparable pregnancy rates with fewer complications.
research Hormonal Organization of Sex Differences in Play Fighting and Spatial Behavior
Gonadal hormones may influence sex differences in play fighting in animals, but their effect on human spatial behavior is unclear and needs more research.
research Delayed Puberty
A 19-year-old male with delayed puberty was successfully treated for a condition that prevents normal hormone production.
research Postmenopausal Hyperandrogenism in a Patient With an Adrenal Adenoma: How Should We Approach It?
Removing both ovaries treated the woman's excess male hormone symptoms.
research Utilisation of gonadotrophin-releasing hormone (GnRH) analogue to differentiate ovarian from adrenal hyperandrogenism in postmenopausal women
GnRH analogue can help diagnose ovarian causes of high testosterone in postmenopausal women when scans don't show the cause.
research Adult Onset Isolated Hypogonadotropic Hypogonadism- a Cause of Secondary Amenorrhea
A 23-year-old woman's missed periods were caused by a rare genetic disorder treated with hormone patches.
research The effect of chemotherapy regimens in male germ cell tumors on the development of primary hypogonadism
Chemotherapy for male germ cell tumors often leads to hypogonadism and related symptoms.
research Androgen Biosynthesis and Gene Defects
Gene mutations can cause problems in male genital development.
research Ovarian steroid cell tumor (not otherwise specified) with subsequent spontaneous pregnancy after tumor removal: a case report and literature review
After tumor removal, the woman regained normal hormone levels, menstruated, and had a healthy baby.
research P-055 MONOZYGOTIC TRANSGENDER MALE TWINS: A CASE REPORT HIGHLIGHTING GENETIC CONCORDANCE IN GENDER DYSPHORIA
Genetics may play a significant role in gender dysphoria.
research Androgens
Male hormones and their interactions are crucial for male sexual development and characteristics.
research New hyaluronan-based biomatrix for 3-D follicle culture yields functionally competent oocytes
A new hyaluronan-based biomatrix successfully supports the growth of mouse ovarian follicles, producing healthy eggs.
research Androgens and ovarian function: translation from basic discovery research to clinical impact
Androgens are important for female fertility and could help in IVF treatment, but also play a role in causing PCOS.
research An adolescent girl presenting with primary amenorrhea: A case report of complete androgen insensitivity syndrome
A 15-year-old girl with no menstrual period was diagnosed with a genetic condition that makes her body unable to respond to male hormones, leading to female characteristics despite having male genetic makeup.
research Effect of gamma-ray exposure on the genome-editing efficiency of improved genome-editing via oviductal nucleic acids delivery (i-GONAD)
Gamma-ray exposure improves genome editing efficiency in mice using the i-GONAD method.
research Estrogens
research Gonadal Suppressive and Cross‐Sex Hormone Therapy for Gender Dysphoria in Adolescents and Adults
Hormone therapy can improve mental health and quality of life for people with gender dysphoria, but long-term effects need more research.
research Restoration of Spermatogenesis and Male Fertility Using an Androgen Receptor Transgene
Scientists restored fertility in male mice lacking a key fertility gene by using a modified gene.
research Female Pseudohermaphroditism Caused by a Novel Homozygous Missense Mutation of the GR Gene
A new gene mutation causes female pseudohermaphroditism due to glucocorticoid resistance.
research Spontaneous fertility in a male patient with testotoxicosis despite suppression of FSH levels
A man with testotoxicosis was fertile despite low FSH levels, suggesting high testosterone may allow sperm production without FSH.
research Ovarian hyperthecosis in adolescent females: two case reports and a review of the literature
Ovarian hyperthecosis should be considered in young women with severe male-like symptoms and can be managed with hormone treatments.
research Anabolic effect of dihydrotestosterone in testicular feminization syndrome
Dihydrotestosterone has a reduced effect on muscle-building in people with testicular feminization syndrome, especially after their gonads are removed.
research GRANULOSA‐THECA CELL TUMOR IN A ONE‐YEAR‐OLD INFANT
A rare ovarian tumor caused early puberty signs in a 1-year-old girl, but surgery reduced hormone levels.
research A Case of Ovarian Hyperthecosis in a Postmenopausal Woman
A postmenopausal woman's excess male hormone symptoms improved after her ovaries were removed.
research Fadrozole and finasteride exposures modulate sex steroid- and thyroid hormone-related gene expression in Silurana (Xenopus) tropicalis early larval development
Fadrozole and finasteride change gene expression related to sex hormones and thyroid hormones in frog larvae development.
research HDAC6-dependent deacetylation of NGF dictates its ubiquitination and maintains primordial follicle dormancy
HDAC6 helps keep ovarian follicles dormant, extending female fertility.
