The anejaculation refers to the inability to ejaculate.

Retrograde ejaculation is a particular case of anejaculation. It occurs when semen pushes backwards into the bladder instead of out the urethra. In these cases it is possible to collect the sperm present in the urine after having had an orgasm and use it in assisted reproduction techniques.

The anejaculatiom or aspermia is the total lack of ejaculate.

The factors causing this disorder may originate from psychological, neurological (spinal cord injury, diabetes, etc.). origin or be obstructive.
