The hypothalamic-pituitary-gonadal axis is regulated by the gonadotropin-releasing hormone pulse generator in the hypothalamus. This is comprised of neurons that secrete kisspeptin in a pulsatile manner to stimulate the release of GnRH, and, in turn, downstream gonadotropins from the pituitary gland, and subsequently sex steroids and gametogenesis from the gonads. Many reproductive disorders in both males and females are characterized by hypothalamic dysfunction, including functional disorders (such as age-related hypogonadism, obesity-related secondary hypogonadism, hyperprolactinemia, functional hypothalamic amenorrhea and polycystic ovary syndrome), structural pathologies (such as craniopharyngiomas or radiation or surgery-related hypothalamic dysfunction), and pubertal disorders (constitutional delay of growth and puberty and congenital hypogonadotropic hypogonadism).

In resource-constrained settings, this training may face unique challenges that might significantly impact learning outcomes and future practice. Despite its importance, the experiences of diagnostic radiography students during clinical placements remain understudied, particularly in Sub-Saharan Africa.

A survey of 6,093 US adolescents was conducted (Mage = 15.27 years, SD = 1.

Objective: 1) Explore differences in unmet LTSS needs by socio-demographic characteristics, including age, sex, race/ethnicity, metropolitan status, sexual orientation, and socio-economic status; and 2) Examine associations between unmet LTSS needs and health/preventative healthcare outcomes.
