Why can't I ejaculate during intercourse?

Failure to ejaculate during sexual intercourse refers to anejaculation, which means that the penis has normal erection and can have normal sexual intercourse, but the man cannot ejaculate semen, and at this time there is no way to reach orgasm. There are many reasons for male anejaculation, including psychological reasons and disease reasons, such as brain diseases, inflammation of the reproductive system, etc., which may cause male anejaculation.

Why can't I ejaculate during intercourse?

During sexual intercourse, the sexual organs (mainly the head of the penis) sense sexual impulses, which are transmitted through afferent nerves to the spinal cord spermatorrhea and ejaculation centers. The efferent nerves then control the effectors (vas deferens, seminal vesicles, ampulla, bladder neck and prostate), inducing ejaculation and accompanying pleasure. This ejaculation reflex is controlled by the brain. If there is functional or organic disorder in any link of the ejaculation pathway, it may lead to ejaculation disorder.

1. Functional anejaculation

(1) Psychological factors are common causes. Dissatisfaction with the spouse, disharmony in the relationship between the couple, great mental pressure, and a bad sexual environment can all cause the man to adopt a restrained attitude towards sex, which can lead to anejaculation in the long run. (2) Lack of sexual knowledge. Both husband and wife lack sexual knowledge and do not know how to have sex, or they have a fear of sex (such as the woman is afraid of pregnancy or pain) and restrict the man from thrusting in a large and rapid manner, which prevents the man from reaching the threshold of ejaculation and leads to anejaculation. (3) Sexual fatigue or ejaculation failure. Frequent sexual intercourse or masturbation can easily cause dysfunction of the spinal ejaculation center and lead to anejaculation. (4) Long-term masturbation Long-term masturbation may cause anejaculation. Because the intensity of sexual stimulation during masturbation is often greater than that during sexual intercourse, the ejaculation center is accustomed to the strong stimulation of masturbation and may not reach the ejaculation threshold during sexual intercourse. On the other hand, due to the influence of traditional concepts, masturbators usually have a sense of guilt and shame, which can also inhibit ejaculation.

2. Organic anejaculation

(1) Nervous system diseases and injuries, such as lateral lobe lesions and spinal cord injuries, can cause anejaculation. (2) Iatrogenic factors such as thoracolumbar sympathectomy and retroperitoneal lymph node dissection can damage nerves and cause anejaculation. (3) Local lesions of the urogenital system such as hypertrophy of the penile vulva, phimosis or excessive foreskin with stenosis of the foreskin opening, penile trauma, nodules, scars, fibrosis, severe hypospadias, etc. can cause anejaculation. (4) Endocrine abnormalities such as diabetes, hypopituitarism, and hyperthyroidism can cause ejaculation disorders. (5) Drug-related factors: Antihypertensive drugs, sedatives or adrenaline blockers, as well as long-term alcoholism or drug abuse can induce anejaculation.
