Common questions about men's health, in a health-guide tone.
Delayed ejaculation and anejaculation sit at the opposite end of the spectrum from premature ejaculation and are rarely discussed. Causes from medicines and hormones to nerve damage and habits, assessment, treatment and options for couples wishing to conceive are covered here.
When no semen comes out despite orgasm, the cause is often retrograde ejaculation, in which semen flows backwards into the bladder. Its causes, diagnosis with a post-ejaculatory urine test, its effect on health and treatment options for couples wishing to have a child are covered here.
