Delayed ejaculation is a medical condition in which a male cannot ejaculate easily or at all.

Premature ejaculation is when a man has an orgasm sooner than desired during intercourse.

 

Retrograde ejaculation occurs when semen goes backward into the bladder. Normally, it moves forward and out of the penis through the urethra during ejaculation.

Erectile dysfunction (ED) is a common type of male sexual dysfunction. It is when a man has trouble getting or keeping an erection.
