What is segmented ejaculation? Can segmented ejaculation increase the chances of conception

Do you know what segmented ejaculation is? During sexual intercourse, males first experience central excitation, causing congestion of the corpus cavernosum and erection. When friction reaches a certain level of stimulation, ejaculation occurs. Below is an answer to what segmented ejaculation is.

Firstly, it starts from the contraction of the testicular output tubules, followed by the contraction of the epididymis head and body, and then the contraction of the epididymis tail. Sperm is expelled into the ampulla of the vas deferens through the vas deferens, and finally, the emptying of the prostate seminal vesicle gland drives the sperm and seminal plasma into the urethra. With the contraction of the bulbocavernosus and ischiocavernosus muscles, as well as the closure of the bladder neck, semen is prevented from retrograde ejaculating into the bladder, causing it to rhythmically ejaculate from the urethra. It is generally believed that the ejaculation process involves seven powerful, rhythmic contractions. We can artificially divide the ejaculation process into two stages, with the first three being one stage, and this part of semen mainly comes from the prostate gland; The remaining few are in one segment, mainly from the seminal vesicles. Generally speaking, the sperm in the first part are significantly higher than those in the second part in terms of density, activity rate, activity, survival rate, and membrane stability. According to statistics, 89% of men have a higher sperm count in the first part than in the second part, with 5% having the same sperm count in the two parts, and 6% having a higher sperm count in the second part than in the first part.

The segmented ejaculation method has great clinical significance in treating male infertility. If the patient's sperm count and activity rate are low, or if the semen is too viscous or excessive, segmented ejaculation can be used during ovulation and sexual intercourse in women. After the first segment of semen is ejaculated, the penis is immediately extracted from the vagina, allowing the rest of the semen to ejaculate outside. This can prevent the seminal vesicle gland secretion from diluting the semen, ensuring that high-density, high-quality, and highly active sperm remain in the vagina, improving the ability to conceive. In the practice of artificial insemination and in vitro fertilization, segmented ejaculation has also become a routine step. After processing the first segment of semen, highly active sperm are screened and sent to the uterus or used for in vitro fertilization.

In clinical biochemical tests, 4-6 parts can also be collected according to the sequence of ejaculated semen. The first part mainly comes from prostatic fluid, with the highest acid phosphatase activity; Finally, the seminal vesicle fluid contains the highest levels of prostaglandins and fructose. By measuring these special enzymes or substances, the function of the accessory glands can be understood. This examination method can also be used to study the physiological activity during ejaculation. Some people suffer from neurological problems, and the ejaculation process is disordered. Sperm is not mainly ejaculated with prostatic fluid, but with seminal vesicle and glandular fluid. Sperm activity is lower than normal. This may also be a cause of infertility.

The significance of segmented ejaculation

The segmented ejaculation method has great clinical significance in treating male infertility and premature ejaculation.

If the patient's sperm count and activity rate are low, or if they are accompanied by excessive semen volume, segmented ejaculation can be used during sexual intercourse during ovulation in women. After the first segment of semen is ejaculated, the penis is immediately extracted from the vagina, allowing the rest of the semen to ejaculate outside. This can prevent the seminal vesicle gland secretion from diluting the semen, ensuring that high-density, high-quality, and highly active sperm remain in the vagina, improving the ability to conceive.
