Testicular mapping-guided sperm retrieval vs. upfront microTESE in non-obstructive azoospermia: a comparison of sperm retrieval, pregnancy and live-birth rates

Translational Andrology and Urology
Sperm extraction by Microscopic Testicular Sperm Extraction (microTESE) has become the standard of care for sperm retrieval (SR) in men with non-obstructive azoospermia (NOA) but is costly and has a 40-50% chance of failure. Fine needle aspiration mapping (FNAM) can be performed prior to microTESE as a predictor of success to reduce the likelihood of ...

Rhyming in the cold: first evidence of soniferous fishes in the Southern Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
The acoustic ecology of Southern Ocean fishes remains unknown due to a lack of dedicated acoustic research on the fishes of this ocean. Passive acoustic monitoring data were collected at the South African sub‐Antarctic Prince Edward Islands using an underwater acoustic recorder, and towed underwater Ski‐Monkey cameras were deployed to identify fish ...

Association of higher serum follicle-stimulating hormone levels with successful microdissection testicular sperm extraction outcomes in nonobstructive azoospermic men with reduced testicular volumes

Asian Journal of Andrology
To investigate the impact of preoperative serum follicle-stimulating hormone (FSH) levels on the probability of testicular sperm retrieval, we conducted a study of nonobstructive azoospermic (NOA) men with different testicular volumes (TVs) who underwent
