Ejaculation occurs in two phases: emission and expulsion. During emission, semen is collected from the prostate, seminal vesicles, and vas deferens. In the expulsion phase, rhythmic muscle contractions propel semen out of the penis. This process is controlled by the sympathetic nervous system and is closely linked to sexual arousal and orgasm.
Normal ejaculation can vary in volume, force, and timing. Some common types include premature ejaculation (occurring too quickly), delayed ejaculation (difficulty or inability to ejaculate), and retrograde ejaculation (semen flows into the bladder). Each type can have different causes, including psychological, neurological, or physiological factors.
Ejaculatory problems may arise from stress, anxiety, relationship issues, hormonal imbalances, nerve damage, or certain medications. Conditions like diabetes, prostate surgery, and spinal cord injuries also increase risk. Age-related changes in testosterone levels and overall health may affect ejaculatory control and performance.
Diagnosis includes a medical history, physical exam, and possibly hormone or neurological tests. Treatment depends on the cause and may include behavioral therapy, medications, pelvic floor exercises, or counseling. Addressing underlying health issues and improving communication with a partner can also support sexual well-being.
See a healthcare provider if ejaculation issues cause stress, interfere with relationships, or persist over time. Medical help is important if accompanied by pain, blood in semen, or erectile dysfunction. Early evaluation can improve outcomes and address both physical and emotional aspects of sexual health.
