research Timing of puberty in relation to semen characteristics, testicular volume, and reproductive hormones: a cohort study
Men who went through puberty later had lower sperm counts and altered hormone levels, possibly affecting fertility.
research Exposure to non-persistent pesticides and sexual maturation of Spanish adolescent males
Certain pesticides may delay sexual maturity in teenage boys.
research Biochemical examination of fetal skin biopsy specimens obtained by fetoscopy: Use of the method for analysis of keratins and filaggrin
Fetal skin biopsy can help diagnose protein-related disorders before birth.
research Alteration of neonatal Allopregnanolone levels affects exploration, anxiety, aversive learning and adult behavioural response to intrahippocampal neurosteroids
Changing Allopregnanolone levels in newborns affects adult behavior and anxiety.
research Puberty in Boys: Correlation of Plasma Levels of Gonadotropins (LH, FSH), Androgens (Testosterone, Androstenedione, Dehydroepiandrosterone and Its Sulfate), Estrogens (Estrone and Estradiol) and Progestins (Progesterone and 17-Hydroxyprogesterone)
Hormone levels change during puberty, leading to physical developments like pubic hair and voice changes.
research Steady-state pharmacokinetics of oral testosterone undecanoate with concomitant inhibition of 5α-reductase by finasteride
Finasteride doesn't affect oral testosterone undecanoate, and high DHT levels may cause acne, prostate issues, and hair loss.
research Inhibition of neurosteroid synthesis increases asphyxia-induced brain injury in the late gestation fetal sheep
Reducing neurosteroid levels worsens brain injury in fetal sheep.
research PMON281 PERSISTENT VIRILIZATION AND VASOMOTOR SYMPTOMS IN A TRANSMAN 5-YEARS POST TESTOSTERONE WITHDRAWAL
A transman experienced lasting virilization symptoms after stopping testosterone, which were resolved with estradiol treatment.
research Longitudinal clinical course in patients with 5α-reductase type 2 deficiency treated with testosterone and dihydrotestosterone during infancy and puberty
Testosterone and dihydrotestosterone treatments can help with penile growth in males with 5α-reductase type 2 deficiency, with dihydrotestosterone being more effective in infancy.
research Interaction between early postnatal neurosteroid manipulations and adult infusion of neurosteroids into CA1 hippocampal region on the open field behaviour
Early neurosteroid changes can alter adult brain function and behavior.
research Effect of Testosterone Supplementation With and Without a Dual 5α-Reductase Inhibitor on Fat-Free Mass in Men With Suppressed Testosterone Production
Testosterone's muscle-building effects do not require its conversion to DHT.
research Sex Steroid Hormones - Impact on Reproductive Physiology
Sex steroid hormones are essential for reproductive health and overall well-being.
research Assessment of Circulating Sex Steroid Levels in Prepubertal and Pubertal Boys and Girls by a Novel Ultrasensitive Gas Chromatography-Tandem Mass Spectrometry Method
Prepubertal girls have higher sex steroid levels than boys, possibly leading to earlier puberty.
research Cardiovascular risks and elevation of serum DHT vary by route of testosterone administration: a systematic review and meta-analysis
Oral testosterone therapy raises heart risk more than other methods.
research GG01-19 FINASTERIDE 1 MG: SILENT IMPACTS ON MALE FERTILITY DESPITE PRESERVED HORMONAL BALANCE
Finasteride 1 mg/day reduces semen quality without affecting hormones or sexual function.
research The Double Edge Sword of Testosterone’s Role in the COVID-19 Pandemic
Testosterone may influence COVID-19 severity and outcomes.
research Respiratory regulation by steroids in newborn rats: a sex‐specific balance between allopregnanolone and progesterone receptors
Breathing in newborn rats is affected differently by hormones based on their sex.
research A pilot study of paternal drug exposure: the Motherisk experience
More research is needed on the safety of fathers' drug exposure before conception.
research Finasteride and male fertility
Finasteride may decrease semen quality but not harm sperm production, and stopping the drug can improve semen quality; hyperprolactinemia can cause infertility but is treatable with medication.
research Neuroactive steroids induce changes in fetal sheep behavior during normoxic and asphyxic states
Neurosteroids help protect fetal brains from asphyxia damage.
research Factors Driving Unique Urination Phenotypes of Male and Female 9-week-old C57BL/6J Mice
Testosterone significantly affects urination differences between male and female mice.
research Re: The Efficacy of Dihydrotestosterone Transdermal Gel Before Primary Hypospadias Surgery: A Prospective, Controlled, Randomized Study
Dihydrotestosterone gel before hypospadias surgery led to less scarring but raised concerns about potential psychological effects and skin changes.
research Risks related to the use of finasteride (propecia) in pregnant women.
research Association between prostate‐specific antigen and serum testosterone: A systematic review and meta‐analysis
Testosterone replacement therapy, especially intramuscular, raises PSA levels, but no overall link between PSA and testosterone was found except in non-BPH patients.
research Sub-chronic testosterone treatment increases the levels of epithelial sodium channel (ENaC)-α,βandγin the kidney of orchidectomized adult male Sprague–Dawley rats
Testosterone increases certain kidney protein levels, potentially raising blood pressure.
research Exposure of Xenopus laevis tadpoles to finasteride, an inhibitor of 5-α reductase activity, impairs spermatogenesis and alters hypophyseal feedback mechanisms
Finasteride exposure harms tadpole reproduction and hormone balance.
research Effection of Epristeride and Finasteride on Spermatogenesis in Male Rats
Finasteride reduces sperm count and affects male reproductive function, while Epristeride does not.
research Maternal Subclinical and Clinical Hypothyroidism Effects on Rat Offspring: A Story of the Skin and its Derivatives
Maternal hypothyroidism harms skin development in rat offspring.
research Disorders in Male Sexual Differentiation Due to 5α-Reductase-2 Deficiency
5α-reductase-2 deficiency causes ambiguous genitalia at birth and affects male sexual development, but individuals often develop male characteristics at puberty.
