What are the hazards of extracorporeal ejaculation? Extracorporeal ejaculation can cause these abnormalities

What are the hazards of extracorporeal ejaculation? Extracorporeal ejaculation refers to a method of pulling out the penis during sexual activity, when ejaculation is about to occur, to allow semen to ejaculate outside the woman's body. Below, the editor will introduce the hazards of extracorporeal ejaculation to you.

The Hazards of Extracorporeal Ejaculation

In medicine, extracorporeal ejaculation refers to a method of ejaculating semen into the female body during sexual activity by pulling the penis out of the female vagina when the male feels about to ejaculate. Extracorporeal ejaculation is the oldest form of contraception, first seen in the Hebrew Bible over 2500 years ago in the West. It was once popular in Europe and other places before the invention of modern contraceptive methods. Extracorporeal ejaculation, as a contraceptive method, although it does not require any cost and is simple and feasible, it has many hazards.

Firstly, external ejaculation can easily cause sexual dysfunction. Male sexual activity is a natural process. After sexual stimulation, the penis becomes congested and erect. As sexual excitement accumulates, semen gradually transports to the urethra and prostate. At this time, the bladder neck and external sphincter of the urethra contract, followed by ejaculation, reaching orgasm and generating great physical and mental pleasure. This natural and joyful process, which comes to a sudden halt when approaching climax, can greatly spoil the scenery and have a negative impact on both parties' psychology. Men can cause disorders in the central nervous system involved in sexual activity and the regulation of ejaculation in the lumbosacral region, leading to non ejaculation and some even erectile dysfunction.

Secondly, external ejaculation can easily lead to contraceptive failure. Extracorporeal ejaculation is a contraceptive method with a high failure rate. Research data shows that the contraceptive failure rate of contraceptive pills is about 0.3%, the failure rate of female intrauterine devices is about 0.6%, the failure rate of condoms is about 2%, and the failure rate of extracorporeal ejaculation is 4%. In some studies, the failure rate of extracorporeal ejaculation is even as high as 15% to 28%. The reasons may include: during sexual activity, a small amount of semen may have entered the female vagina before male ejaculation, and the concentration of sperm in this part of the semen is relatively high; It is sometimes difficult to grasp the timing of external ejaculation, which may result in a small amount of semen ejaculating into the female vagina; After extracorporeal ejaculation, the male partner contacts the female perineum with his hand or penis, and some sperm may enter the female reproductive tract as a result, which may lead to contraceptive failure. Once contraception fails, it may cause certain harm to both men and women.

Finally, it leads to tension in the relationship between partners. Extracorporeal ejaculation disrupts the natural process of sexual activity and may have adverse psychological effects on both parties, even causing sexual apathy and affecting the quality of sexual life; There may also be misunderstandings between partners due to contraceptive issues, which can affect relationships.

Therefore, it is recommended that men avoid using extracorporeal ejaculation as much as possible. Of course, if there are no other effective contraceptive measures available, it is also possible to consider temporary emergency measures, but do not use them frequently.

Healthy and feasible contraceptive methods

Condoms are the least harmful form of contraception, and the vast majority of people use condoms for contraception. But some people believe that wearing a condom on the penis can hinder direct contact between the penis and the vagina, thereby affecting the pleasure of sexual intercourse. So, what other methods of contraception can be achieved without a condom?

Oral contraceptive pills

Oral contraceptives are sex hormone drugs that can have sexual effects on certain women. However, this impact is often bidirectional, with some women experiencing decreased libido or sexual dysfunction; Some women, on the other hand, exhibit increased sexual sensitivity and sexual ability after taking medication. The key lies in their understanding and attitude towards contraceptives. For the vast majority of women, the impact of oral contraceptives on sexual activity is minimal.

Safe period contraception method

The safety period is divided into pre ovulation safety period and post ovulation safety period. The period from the day of clean menstruation to the day before ovulation is considered the safe period before ovulation. The safe period after ovulation is from the first day after the end of the ovulation period to the day before the next menstrual cycle. The safe period after ovulation is safer than the safe period before ovulation. This is because some women are sometimes influenced by environmental changes and emotional fluctuations to ovulate earlier, which shortens the pre ovulation safety period without realizing it. Therefore, the pre ovulation safety period is not very safe.

The period from three days before ovulation to two days after ovulation is the danger period, while the other days are the safety period. But the calculation of the safe period is easier for women with regular menstrual cycles (see calculation of ovulation date); People with irregular cycles are not suitable for this method. The unexpected pregnancy rate within one year is 20%.

Using a vaginal ring

It is a soft, transparent rubber contraceptive tool that can slowly break down hormones, estrogen, and flavonoids. The diameter of the vaginal ring is about two inches, and it acts as a contraceptive by placing it inside the vagina. Each vaginal ring can have contraceptive effects within a month.

The success rate of vaginal ring contraception is similar to that of hormonal contraception, with a contraception rate of 92%. This means that on average, only 8 out of 100 women who use vaginal rings experience unintended pregnancy.

The side effects of vaginal rings include: vaginal infection, vaginal itching, abnormal vaginal bleeding, headache, chest tightness, weight gain or loss, dizziness, vomiting, abdominal distension, decreased libido, and emotional depression. Women who use vaginal rings have a slightly higher risk of developing heart disease and stroke compared to other women.

Vaginal septum and uterine cap

Vaginal septum is prone to displacement due to improper use, which can cause sexual discomfort; The uterine cap is firmly fixed on the cervix and will not shift due to vaginal dilation, so it has less impact on sexual activity. It is a safe and reliable contraceptive tool for women. When used, place it at the top of the vagina to cover the cervical opening, preventing sperm from entering the uterine cavity, thus achieving the purpose of contraception.

Generally, the vaginal diaphragm is removed 8-12 hours after sexual intercourse. The live time of sperm in the vagina is 8-12 hours. If removed too early, some sperm may still have the ability to move in the vagina and enter the cervix and uterine cavity, leading to pregnancy, and contraception may fail. The storage time should not be too long, not more than 24 hours, to avoid stimulating the vaginal wall, causing excessive secretion and causing discomfort or infection.

Physiological knowledge of extracorporeal ejaculation

The neurophysiology of extracorporeal ejaculation involves only one-sided segments being mated. Research has shown that the dopamine system promotes in vitro ejaculation, while the serotonin activated system outperforms in vitro ejaculation. The main neural mechanism of extracorporeal ejaculation is the innervation of the body, but it also includes nerves and fibers from the democratic nervous system in the genitals. The democratic branch of the parasympathetic nerve mainly inhibits erectile function, while the sympathetic and somatic branches mainly inhibit emission and external ejaculation.

During sexual activity, the discovered stimulation passes through the pubic nerve (belonging to the somatic nerve) and penetrates the sacral plexus to the spinal cord. The precise location for inhibiting external ejaculation has not yet been elucidated, but the hypothalamus is believed to be involved in this. The external ejaculation center in the brain emits stimulation impulses to the sympathetic nervous system of the spinal cord, which pass through the upper lower abdominal plexus and lower abdominal nerves to reach the scrotum, vas deferens, prostate, and other organs related to male external ejaculation. The sympathetic nerve innervating the bladder neck closes the bladder neck, which is necessary to prevent retrograde external ejaculation. Both neural messages from the superior central nervous system and spinal cord reflexes are transmitted to the sacral plexus, passing through the motor branches of the perineal nerves to the striated muscles of the perineum, resulting in rhythmic contractions characterized by extracorporeal ejaculation. These muscles include the bulbocavernosus muscle, the ischiococcygeal muscle, and the pubococcygeal muscle.
