The lack of semen flow every time you have intercourse may be caused by failure to reach orgasm, retrograde ejaculation, obstructive azoospermia and so on.
1. Failure to reach orgasm: It may be due to the failure to reach orgasm during intercourse, which often leads to the inability to ejaculate and the natural weakness of the penis.
2. Retrograde ejaculation: the patient will often have the feeling of ejaculation, but the semen will not be discharged from the urethra, but will often enter the bladder retrogradely and flow out with the urine during urination.
3. Obstructive azoospermia: Often the semen cannot flow out because of bilateral ejaculatory duct stenosis or other causes of obstruction.
Every time there is no semen flow, there may be other reasons, it is recommended to go to the hospital in a timely manner, to identify the causes and then targeted treatment.
