パイプカット再建 / 元に戻す(日帰り顕微鏡下パイプカット再建術)

At our clinic, we perform both vasectomy and reconstruction (restore) of vasectomy that you had in the past. We are waiting for consultation on the surgery from the appointment page for your first visit.

After undergoing vasectomy , surgery to restore (recanalize) for the purpose of vocational training for reasons such as remarriage is “One-Day Microsurgical Vasectomy”. The vas deferens are recanalized by re-anastomizing the vas deferens obstruction using a surgical microscope. This page introduces the flow and cost of surgery related to vasectomy, and frequently asked questions.

Treatment results of our clinic

At our clinic, vasectomy has a very high results as follows.

  • Sperm appearance rate91%
  • Semen normalization rate47%


What is Vasectomy

Vasectomy (vas deferens ligation) is also called pipe cut. This is a male contraceptive surgery performed when a person who already has children does not wish to have any more children. Sperm produced in the testes pass through the vas deferens and mix with the secretions of the prostate and seminal vesicles to become semen, which is ejaculated outside the body with sexual stimulation. Vasectomy (vas deferens ligation) is an operation in which the vas deferens is cut (excised or closed) in the middle to block the passage of sperm and prevent sperm from being mixed with semen. It also has no effect on sexual function or sexual sensation.

What is Vasectomy Reversal?

Vasectomy reversal (vas deferens anastomosis) re-anastomizes the vas deferens obstruction using a surgical microscope to recanalize the vas deferens. Since sperm may not be produced at 10%, Simple TESE may be performed at the same time.

Who wants to undergo reconstruction

Most people undergo this surgery to get it back for the purpose of giving birth because of remarriage.

Benefits of reconstruction

By restoring it, you will be able to expect a natural pregnancy. In addition, the treatment results of pipe cut reconstruction (vas deferens anastomosis) at our clinic are the highest with a sperm appearance rate of 91% and a semen normalization rate of 47%.

Disadvantages of reconstruction

It takes 2 to 6 months for sperm to appear. On the other hand, there is a 9% chance that sperm will not appear. In this case, intratesticular sperm recovery (SimpleTESE) is required.
If you do not wish for pregnancy, you will need contraception


Flow of vasectomy reversal

From signing up to preoperative

First, please make an appointment for a medical examination and have an examination. After the examination, the doctor will explain the surgery in detail.
If you wish to have surgery after that, you will be asked to undergo a preoperative examination (a blood test for infectious diseases).

Infertility treatment after vasectomy other than vasectomy reverse

  • Epididymal sperm extraction (MESA) / Intratesticular sperm extraction (TESE)
    Usually, epididymal sperm extraction (MESA) or intratesticular sperm extraction (TESE) collects sperm directly from the epididymis or testis for the purpose of microinsemination when sperm are not present in the semen.

    If you had a vasectomy and wish for pregnancy, you usually have a vasectomy reverse, but if you don’t get the results you want, these surgeries may be done.
    If you wish, we will introduce you to the Toho University Omori Hospital Reproduction Center (Urology Department), which is affiliated with this clinic.
    For details, please see the link below and the site of the Toho University Omori Hospital Reproduction Center (Urology).


  • TESE testicular sperm extraction
    Normally, Simple TESE is expected to have a high probability of recovering sperm without any problem in sperm formation function by simply not recognizing sperm in the ejaculated semen, such as obstructive azoospermia and ejaculatory disorder. It is done in cases, but it may also be done if you wish for pregnancy.
    Sperm can be collected by collecting only a small part of the tissue of the testis, and the size of the wound can be reduced.
