Is the success rate of contraception with extracorporeal ejaculation high?

I believe that many people have used the extracorporeal ejaculation contraceptive method, but this method actually has many disadvantages. The possibility of contraceptive failure is also relatively high. In addition, long-term sudden interruption of sexual intercourse can easily induce sexual dysfunction.

1. Advantages of extracorporeal ejaculation

Many people like to use the external ejaculation method for contraception because taking birth control pills has serious side effects, such as depression, vaginal dryness, loss of libido, weight gain, headaches, etc. The external ejaculation method does not require any cost, does not require any tools or drugs, has no physical side effects, and does not affect the pleasure of sex.

2. Disadvantages of extracorporeal ejaculation

Compared with using condoms, taking birth control pills, and using contraceptive rings, the success rate of the external ejaculation method is relatively low. Although the use of the external ejaculation method does not cost anything, due to the low success rate, users have to bear a greater risk of pregnancy.

If your partner has a sexually transmitted disease or AIDS, using the external ejaculation method does not prevent infection, because viruses and bacteria can also be transmitted to each other through body fluids and mucous membranes.

If the man suddenly interrupts sexual intercourse when he orgasms, it will cause frustration to the other party and make the partner dissatisfied. Scientists Masters and Johnson believe that frequent use of extracorporeal ejaculation can cause premature ejaculation or impotence.

During sexual intercourse, a man's penis will become erect due to sexual excitement. If sexual intercourse is forcibly terminated at this time, the function of the central nervous system and the lumbar ejaculation center will be impaired. Over time, he will easily suffer from functional anejaculation.

3. The process of extracorporeal ejaculation

The first step is that the sympathetic nerves send out impulses that cause the smooth muscles of the vas deferens and seminal vesicles to contract, thereby transferring the semen in the vas deferens and seminal vesicles to the urethra;

The second step is to contract the transverse muscles at the root of the corpus cavernosum of the penis with the help of the outgoing impulse of the pudendal nerve, thereby ejecting the semen in the urethra. The excitement of the superior part of the brain travels down the path and also acts on the erection center and the extracorporeal ejaculation center of the spinal cord. Normal human sexual excitement stimuli come from various senses that travel through the brain and affect spinal reflex behavior.
