Ultrasound is a helpful imaging tool for triaging and in most instances making a definitive diagnosis of abnormalities of the fetal and neonatal genitourinary systems. Ultrasound can define an abnormality found in a fetus or neonate as definitively related to the genitourinary system, guiding further workups. Ultrasound can be used to assuage clinical concern by showing normal anatomic findings or variants that can simulate abnormality. This article discusses necessary information to aid in ultrasound diagnosis in various areas of the perinatal genitourinary system including the kidneys, bladder, and genital system. It discusses some adrenal findings that may help in these diagnoses.

Background: Infertility is a significant issue in spinal cord injury (SCI) patients. Men with SCI often experience erectile and ejaculatory dysfunctions, and low sperm quality leading to impaired fertility. In this study, we investigated the effectiveness of Erythropoietin (EPO)alginate/chitosan (CH-AL) hydrogel on SCI-induced male rat infertility.

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.

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: Despite extensive analysis, the dynamic changes in prostate epithelial cell states during tissue homeostasis as well as tumor initiation and progression have been poorly characterized. However, recent advances in single-cell RNA-sequencing (scRNA-seq) technology have greatly facilitated studies of cell states and plasticity in tissue maintenance and cancer, including in the prostate.

Methods: We have performed meta-analyses of new and previously published scRNA-seq datasets for mouse and human prostate tissues to identify and compare cell populations across datasets in a uniform manner.
