@ridaz Hello, Post-ejaculation urinalysis. Sperm in your urine can indicate your sperm are traveling backward into the bladder instead of out your penis during ejaculation retrograde ejaculation. Other tests like Scrotal ultrasound, Transrectal ultrasound, Hormone testing, Post-ejaculation urinalysis, Genetic tests, Testicular biopsy, and Specialized sperm function tests can be helpful. A number of tests can be used to check how well your sperm survive after ejaculation, how well they can penetrate an egg, and whether there's any problem attaching to the egg. Thanks!
