Gonadotropins for pubertal induction in males with hypogonadotropic hypogonadism: systematic review and meta-analysis. [PDF]

OBJECTIVE: Hypogonadotropic hypogonadism is characterized by inadequate secretion of pituitary gonadotropins, leading to absent, partial, or arrested puberty. In males, classical treatment with testosterone promotes virilization but not testicular growth

Effect of Salinity Stress on Gut–Brain–Gonad Axis in the Red‐Eared Slider (Trachemys scripta elegans)

Integrative Zoology, EarlyView.
The increase in salinity leads to changes in the gut microbiota and metabolites of Trachemys scripta elegans, affecting the synthesis and secretion of neurotransmitters or precursors, which can inhibit the secretion of reproductive hormones and affect the self‐renewal and differentiation process of spermatogonial stem cells.

Pituitary hormones in teleost fish with emphasis on gonadotropins

, 1979
This investigation on fish gonadotropins provides considerable evidence to support the concept of duality of gonadotropins in teleosts proposed by Campbell and Idler in 1976.

Morphotype Bias, Morph Specific Recruitment and No Elevation‐Life History Relation in High Altitude Mesquite Lizard Populations

Integrative Zoology, EarlyView.
Site‐level differences in population growth (λ) and phenotype frequencies. Mountain silhouettes represent the three study sites. Morph relative abundances are shown in the colored vertical bar. Point estimates and confidence intervals of λ for each site are displayed below, with the dashed line marking the threshold for demographic stability (λ = 1 ...

CDK4/6 Inhibitors in the Management of Hormone Receptor‐Positive (HR+)/Human Epidermal Growth Factor Receptor 2‐Negative (HER2−) Advanced Breast Cancer in Indonesia: Challenges, Opportunities, and Recommendations

Asia-Pacific Journal of Clinical Oncology, EarlyView.
Evidence‐informed recommendations emphasize the integration of CDK4/6 inhibitors with endocrine therapy as a central component in the management of HR+/HER2− advanced breast cancer in Indonesia. Expanding access and facilitating integration within national treatment frameworks are crucial to improve outcomes and reduce disparities in care.

Semen quality in patients with testicular cancer is associated with age and with greatly elevated levels of beta human chorionic gonadotropin

Andrology, EarlyView.
Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

Andrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.
