Question: vasectomy and sperm questions


 cypher - Thu Dec 10, 2009 3:39 pm

I recently had a vasectomy 7 months ago, the method was the scalpel method and the vas deferans were clipped and cauterized. I've had 4 sperm tests done in those 7 months and all of them have come back negative. After doing research online and reading about couples getting pregnant after having a vasectomy and having negative sperm tests i was wondering if any of you have heard of this and what chances there are to getting pregnant even if the sperm tests keep coming back negative AND also if the man always withdrawals before ejaculation.

Thanks

User avatar Hi,
That pregnancies can occur post-vasectomy or post-tubectomy is well known.

Some of the causes of pregnancies in the post-vasectomy period are....
- Unprotected intercourse during the immediate post-vasectomy period.
- recanalization of the vas
- or other less common causes which can be called as 'method failure'.

A common recommendation for the post-vasectomy period is to have semen analysis performed 3 months after vasectomy or after 20 ejaculations and use temporary contraception or to avoid intercourse until azospermia is documented.

The time interval from vasectomy to azoospermia is incompletely characterized and may vary according to the vasectomy technique.Thus it is important for couples to understand that men are not sterile immediately after the procedure.

Although most vasectomy failures are said to occur relatively early (within 6 months of the procedure), some may occur more than a year after the vasectomy (most failures occurred within the first 2 years).

Vasectomy failures more than 2 years after vasectomy have also been reported.

Withdrawals before ejaculation are not an insurance against the risk of pregnancies.

Best wishes!
