Sperm recovery from urine in men with retrograde ejaculation.

Introduction: Retrograde ejaculation (RE) consists of the reflux backwards, towards the bladder, of the ejaculate, during the emission phase of ejaculation, causing a total or partial absence of sperm emission, with the consequent diversion of semen into the bladder during the emission phase of ejaculation. Evaluating the ejaculate may not be sufficient for identifying RE in some patients. Hence, the management of infertility may involve the use of invasive methods such as epididymal fluid retrieval or testicular biopsy.

Comparing quantity of marine debris to California horn shark sightings and egg appearances in Redondo Beach, California, USA.

Marine debris such as plastic, metal, and rubber, is a significant source of anthropogenic waste pollution in oceanic waters. Debris continues to be found along Southern California's coastlines and poses serious risks to biodiversity and ecosystem health through entrapment, ingestion, and entanglement. One particular species that drops eggs in the South Bay, particularly in the Palos Verdes peninsula, is the California horn shark (Heterodontus francisci).

Veterinary Student Skills Learned at an Access to Care Clinic: Beyond Medicine and Surgery.

Incorporating curriculum to effectively help veterinary students learn how to provide accessible quality care to is needed. The primary aims of this study are to explore how a 2-week rotation at a veterinary medical service-learning clinic (Wisconsin Companion Animal Resources, Education, and Social Services [WisCARES]) improves (a) comfort in working with clients from diverse race and low socioeconomic (SOCI) backgrounds and (2) confidence in leading cases, communication skills, and providing a spectrum of care options. Students were surveyed at five time points pre-rotation: mid-week 1, mid-week 2, end of rotation, and 1-month post.
