No. The sex hormones made by the testicles (testes) - for example, testosterone - continue to be passed into the bloodstream as before. Also, vasectomy does not reduce the amount of semen when you come (ejaculate) during sex. Sperm only contribute a tiny amount to semen. Semen is made in the seminal vesicles and prostate higher upstream.
Sex may even be more enjoyable, as the worry or inconvenience of other forms of
contraception is removed.

Sperm are still made as before in the testicles (testes). The sperm cannot get past the blocked vas deferens and are absorbed by the body.

Do not consider having the operation unless you and your partner are sure you do not want children, or further children. Consider all sorts of situations, including a tragedy in the family or a break-up of your relationship. Only have a vasectomy if you are sure you would not want more children even in those situations.

It is wise not to make the decision at times of crisis or change, such as after a new baby or
termination of pregnancy. It is best not to make the decision if there are any major problems in your relationship with your partner.

Remember there are reversible forms of long-term contraception which are very effective.
Consider these as a couple before making your decision. These are all for women.
Ideally, both partners are happy with the decision before a vasectomy. However, it is not
legally necessary to obtain your partner’s permission.

Yes – but unfortunately the wait times can be very long (2-5 years).

No more than any other minor operation that uses local anaesthetic. The injection of local
anaesthetic may sting a bit for a few seconds. It is put in just a small area of skin. After this, the operation is usually painless. After the operation, when the local anaesthetic wears off, the top part of the scrotum is normally mildly sore for a few days.

We also have the option of additional pain relief in the form of the Penthrox “Green whistle” if discomfort remains.

If you are very nervous about the procedure, you can talk to our doctors about a “pre-medication” to help relax you. If you decide on oral sedation, you will need someone else to drive you to and home from the procedure.

Vasectomy is considered permanent. There is an operation to re-unite the two cut ends of the vas deferens. It is a difficult operation and not always successful. It is also not available through medicare, so you would have to pay for this yourself. There is also the option to utilise invasive IVF methods to harvest sperm from the testes with a needle.

It is recommended to abstain from sex for between 2 to 7 days after the vasectomy.

However, remember you will have to use other methods of contraception until your semen specimen has been confirmed as clear of sperm. Some sperm will survive upstream from the cut vas deferens for a few weeks.

Sperm adds very little to the semen volume, so you shouldn’t notice any change in your
ejaculate after vasectomy. Your partner may sometimes be able to feel the vasectomy site. This is particularly true if you have developed a granuloma (small pea-like palpable scar tissue).

Ejaculation and orgasm are not affected by vasectomy. The special case is the rare man who has developed post-vasectomy pain syndrome.

A vasectomy does not cause erectile dysfunction.

In rare cases, the testicular artery may be hurt during vasectomy. Other problems, such as a mass of blood (hematoma) or infection, may also affect the testicles.
