Diagnosing growth hormone deficiency (GHD) remains a challenge, and the role of sex steroid priming in the diagnosis of GHD continues to be debated. This review examines existing data on sex steroid priming during GHD diagnosis. Primary literature was reviewed in the area of sex steroid priming and growth hormone stimulation tests. Studies supporting sex steroid priming suggest improved diagnostic efficiency with reduced false diagnosis of GHD in peripubertal children. Those that do not support sex steroid priming note the potential for underdiagnosis of GHD and the lack of standardization in sex steroid priming procedures. To date, there is no consensus on the use of sex steroid priming prior to performing growth hormone stimulation tests in the evaluation of GHD. A more targeted approach to using sex steroid priming may be reasonable; however, the decision of whether or not to use sex steroid priming should remain with the individual clinician.

Skin cancers continue to present unresolved challenges, particularly regarding the association with sex hormones, which remains a topic of controversy. A systematic review is currently warranted to address these issues. To analyze if sex hormones result in a higher incidence of skin cancers (cutaneous melanoma, basal cell carcinoma, squamous cell carcinoma).

Granulosa cells (GCs) are pivotal in the development of ovarian follicles, serving not only as supportive cells but also as the primary producers of steroid hormones. The proliferation of these cells and the synthesis of steroid hormones are crucial for follicular development and atresia. In our study, GCs were isolated using follicular fluid aspiration and subsequently identified through immunofluorescence.

Background: The oxidative handicap hypothesis posits that testosterone-dependent traits, such as muscle mass and strength, may be costly to develop due to testosterone's pro-oxidative properties, leading to increased oxidative stress. This hypothesis suggests that only individuals with superior biological conditions can afford these costs. This study examines the oxidative handicap hypothesis, exploring the relationship between muscle mass or handgrip strength and oxidative stress markers in men.

It is well known that vitamin D is essential for human health; however, many people suffer from vitamin D deficiency or insufficiency worldwide, including in Japan. Serum 25-hydroxyvitamin D (25(OH)D) concentrations are typically measured to evaluate vitamin D status. In a previous study, we demonstrated that the concentrations of vitamin D metabolites in urine, measured using the NLucVDR assay system composed of a split-type nanoluciferase and the ligand-binding domain (LBD) of the human vitamin D receptor, correlated with serum 25(OH)D concentrations measured using liquid chromatography-mass spectrometry (LC-MS) or electrochemiluminescence immunoassays (ECLIAs).

Background: Sex steroid hormones are critical for maintaining pregnancy and optimal fetal development. Air pollutants are potential endocrine disruptors that may disturb sex steroidogenesis during pregnancy, potentially leading to adverse health outcomes.
Methods: In the Environmental influences on Child Health Outcomes Understanding Pregnancy Signals and Infant Development pregnancy cohort (Rochester, NY), sex steroid concentrations were collected at study visits in early-, mid-, and late-pregnancy in 299 participants.
