Purpose: To evaluate the macular development in preterm infants with spontaneously regressed retinopathy of prematurity (ROP) utilizing handheld spectral domain optical coherence tomography (SD-OCT) during the early postnatal period.
Design: A cross-sectional observational study.
Methods: Using handheld SD-OCT, OCT images were acquired in non-sedated infants ages about 37 weeks(w) post-menstrual-age (PMA = gestational age in weeks + chronological age).

Background: There is inconsistent evidence as to the role of testosterone and pre-androgens in premenopausal female sexual function, and reported associations between blood concentrations of these hormones and female sexual function vary in strength.
Aim: To examine the patterns of testosterone and pre-androgen concentrations and variations in sexual function in premenopausal eumenorrheic women.
Methods: This was a secondary analysis of a sample of 588 premenopausal eumenorrheic women from the Grollo-Ruzzene Foundation Young Women's Health Study.

Menstrual effluent cell profiles have potential as noninvasive biomarkers of female reproductive and gynecological health and disease. We used DNA methylation-based cell type deconvolution (methylation cytometry) to identify cell type profiles in self-collected menstrual effluent. During the second day of their menstrual cycle, healthy participants collected menstrual effluent using a vaginal swab, menstrual cup, and pad.

Kisspeptin and neurokinin B (NKB) play a key role in several physiological processes including in puberty, adult reproductive function including the menstrual cycle, as well as mediating the symptoms of menopause. Infundibular kisspeptin neurons, which co-express NKB, regulate the activity of gonadotropin releasing hormone (GnRH) neurons, and thus the physiological pulsatile secretion of GnRH from the hypothalamus. Outside of their hypothalamic reproductive roles, these peptides are implicated in several physiological functions including sexual behavior and attraction, placental function, and bone health.
