Steroid hormones, especially progesterone (P), estradiol (E), and testosterone (T), are key bioactive regulators in various female physiological processes, including growth and development, ovulation, and the reproductive cycle, as well as metabolism and mental health. As lipophilic molecules produced in sex glands, these steroid female hormones can be transported through blood vessels into various body fluids such as saliva, sweat, and urine. However, the ultralow concentration of steroid hormones down to picomolar (pM) level necessitates great demands for ultrasensitive but low-cost analytic tools to implement accurate, point-of-care or even continuous monitoring in a user-friendly fashion.

Overreaching, a consequence of intensified training, is used by athletes to enhance performance. A blunted hormonal response to a 30-min interval exercise stress test (55/80) has been shown in males after intensified training, highlighting cortisol and testosterone as potential biomarkers of overreaching. Despite accounting for ~50% of the population, studies into hormonal responses to exercise in females are lacking.

Saliva samples offer the possibility to obtain stress-free non-invasive samples, also for home-testing, especially useful when blood collection is either undesirable or difficult. The aim of this work was to develop an LC-MS/MS method to determine clinically relevant steroid hormones cortisol, cortisone, 11-deoxycortisol, 21-deoxycortisol, 17OH-progesterone, aldosterone, corticosterone, deoxycorticosterone, testosterone, androstenedione, DHEAS, DHEA, 17OH-pregnenolone, betamethasone and dexamethasone. A special effort was made to adapt the method to neonatal population with respect to choice of saliva as matrix, low sample volumes, selection of analytes and multiplexing.

Objective: The purpose of this study was to address the lack of data on the stress and motivation response in master athletes during competitions, as athletic performance in this age group can be significantly impacted by stress rather than appropriate training.
Methods: Coastal rowing beach sprint master athletes aged 43-57 years were examined to assess the saliva levels of stress biomarkers, cortisol, and testosterone. Specifically, samples were collected at awakening and before and after the boat race.
The Impact of Maternal Gestational Diabetes Mellitus on Minipuberty in Boys.

Background/objectives: Minipuberty is thought to play an important role in the sexual maturation of infants. Maternal disorders during pregnancy were found to have an impact on the activity of the reproductive axis in the first year of life. This prospective, matched, cohort study was aimed at investigating whether the course of minipuberty in boys is affected by maternal gestational diabetes mellitus (GDM).
