  • Monorchidism in a phenotypic mare with a 64,XY, SRY-positive karyotype. [Case Reports]
    J Equine Vet Sci. 2023 Feb 01 [Online ahead of print]Middlebrooks B, McCue P, … Conley A
  • Disorders of sexual development (DSD) are associated with atypical chromosomal, gonadal, or phenotypic sex. It is likely that the number of cases of DSD are underestimated in the equine population. Monorchidism in the horse is very rare. This case report describes the clinical assessment of a phenotypic mare with stallion-like behavior which led to the diagnosis of a DSD. A 4-year-old Quarter Hor…
  • Maternal phthalate exposure during pregnancy and testis function of young adult sons. [Journal Article]
    Sci Total Environ. 2023 Jan 31 [Online ahead of print]Henriksen LS, Frederiksen H, … Main KM
  • CONCLUSIONS: In this exploratory study, higher maternal exposure to some phthalates was associated with impaired testicular Leydig cell function evidenced by a lower total and free testosterone/LH ratio in adult sons. This unique 18-20-year follow-up study raises concern and suggests that exposure of pregnant women to phthalates may have long-term effects on adult reproductive health in male offspring.
  • Urinary Tract Infections Among Gender Diverse People Assigned Female at Birth on Testosterone. [Journal Article]
    Urogynecology (Hagerstown). 2023 Feb 01; 29(2):295-301.Wong JWH, Xu RH, … Zaritsky EF
  • CONCLUSIONS: The rate of UTIs among our young cohort of GDT and CW was similarly low. Diabetes mellitus type 1 or 2 was significantly associated with UTIs among CW but not GDT. These findings suggest that testosterone-induced vaginal atrophy may not be associated with a higher a UTI risk. A deeper understanding of the pathogenesis of UTI in people assigned female at birth and more data on the relationship between testosterone and UTIs are needed before recommending vaginal estrogen to all GDT with recurrent UTI.
  • Do testosterone and cortisol levels moderate aggressive responses to peer victimization in adolescents? [Journal Article]
    Dev Psychopathol. 2023 Feb 03 [Online ahead of print]Calvete E, Orue I
  • Aggressive reactions to peer victimization may be tempered by hormone levels. Grounded on the dualhormone hypothesis (DHH), which proposes that testosterone (T) is associated with aggressive behavior only when cortisol (C) is low, this study assessed whether the combination of T and C moderated adolescents' aggressive responses to peer victimization. The study involved 577 adolescents (50.4% girl…
  • Effects of time-restricted feeding on letrozole-induced mouse model of polycystic ovary syndrome. [Journal Article]
    Sci Rep. 2023 Feb 02; 13(1):1943.Ryu KJ, Park H, … Kim T
  • The present study aimed to investigate whether time-restricted feeding (TRF) ameliorates metabolic and reproductive phenotypes in a letrozole-induced mouse model of polycystic ovary syndrome (PCOS). Sixty female C57BL/6 N mice were randomly divided into two groups according to the type of food received: either a chow or a 60% high-fat diet. Those mice were subcutaneously implanted with letrozole …
  • Testosterone and Cortisol Salivary Samples Are Stable Across Multiple Freeze-Thaw Cycles. [Journal Article]
    J Strength Cond Res. 2022 Nov 17 [Online ahead of print]Sontag SA, Cabarkapa D, Fry AC
  • Sontag, SA, Cabarkapa, D, and Fry, AC. Testosterone and cortisol salivary samples are stable across multiple freeze-thaw cycles. J Strength Cond Res XX(X): 000-000, 2022-When processing salivary samples for biomarker analysis, avoiding multiple freeze-thaw cycles is generally recommended. However, confusing tissue handling instructions or challenges with collections in the field sometimes makes t…
  • The sex life of male patients with cirrhosis and its organic factors: What we have got so far? [Journal Article]
    PLoS One. 2023; 18(2):e0280915.Darmadi D, Pakpahan C, … Ibrahim R
  • CONCLUSIONS: The sex life of cirrhotic men is affected. The decrease in the frequency of intercourse and sexual satisfaction is noticeable in male patients and leads to increased masturbation. Free Testosterone, vitamin D, albumin, and bilirubin play role in their sex life. In addition, ascites and sarcopenia not only affect their sex life but also hamper the quality of their well-being.
  • Supra-physiological doses of anabolic androgenic steroids impact erythropoietin and blood parameters. [Journal Article]
    Drug Test Anal. 2023 Feb 02 [Online ahead of print]Heiland CE, Schickel Y, … Ekström L
  • Hematological parameters and erythropoiesis are known to be influenced by anabolic androgenic steroid (AAS) use. However, little is known in relation to supra-physiological doses of AAS. Therefore, the aim of this study was to evaluate the effect of supra-physiological doses of AAS on serum and urinary erythropoietin (EPO), and blood parameters, from self-reported AAS users. Serum EPO levels were…
  • Dietary trends and the decline in male reproductive health. [Review]
    Hormones (Athens). 2023 Feb 02 [Online ahead of print]Whittaker J
  • Over the twentieth century, male reproductive health has suffered a substantial decline, as evidenced by decreases in sperm counts and testosterone levels and increases in reproductive pathologies. At the same time, the prevalence of chronic diseases such as obesity, diabetes, and metabolic syndrome has risen dramatically. Metabolic and reproductive health are highly interconnected, suggesting th…
  • Steroid Hormones in Seminal Plasma: the Relationship with Sperm Quality. [Journal Article]
    Bull Exp Biol Med. 2023 Feb 01 [Online ahead of print]Osadchuk LV, Kleshchev MA, Osadchuk AV
  • The purpose of this study was to find out whether the seminal testosterone and/or estradiol levels could serve as prognostic criteria for normal spermatogenesis and whether they are able to characterize the sperm pathology. The study involved healthy young male volunteers (n=269); serum and seminal steroid hormones were measured; the sperm concentration, mobility, and morphology were evaluated. T…
  • Eight weeks of androgen priming by daily low-dose hCG injections before ICSI treatment in women with low ovarian reserve. [Journal Article]
    Hum Reprod. 2023 Jan 31 [Online ahead of print]Friis Wang N, Bogstad JW, … Løssl K
  • CONCLUSIONS: The proportion of antral follicles (2-10 mm) that reached the preovulatory state did not increase.The sample size was small, and the number of oocytes retrieved was not the primary endpoint. Larger studies are needed to confirm this finding.Long-term, low-dose rhCG administration may increase the number of oocytes retrieved during IVF/ICSI in women with low ovarian reserve, but more research is needed before firm conclusions can be drawn.
