If you wish to have a child with your own sperm but don’t want to have a vasectomy reversal, your doctor can remove sperm from your body through a process called sperm aspiration. This process involves retrieving sperm from either your epididymis or testes to be used in IVF or intracytoplasmic sperm injection (ICSI).

There are two main types of non-surgical sperm aspiration. Percutaneous Epididymal Sperm Aspiration (PESA) involves retrieving sperm from your epididymis, located just above your vas deferens. A fine needle is inserted through the skin into the epididymis, and some liquid is removed. This liquid should contain sperm. Testicular Sperm Extraction (TESE) involves using a biopsy needle to remove small pieces of tissue from your testes. This tissue contains small amounts of sperm, which can be extracted and used in IVF or ICSI.

Non-surgical sperm aspiration generally involves few side effects and no complications. Rarely, infections can occur at the injection or biopsy site. If your partner is willing to undergo IVF or ICSI, sperm aspiration may be a good alternative to a vasectomy reversal. However, IVF and ICSI have lower success rates than the vasectomy reversal.

Typically, between 20% and 35% of patients conceive a child using these methods. These procedures generally have to be performed on numerous occasions, because few women become pregnant after only one attempt. Unfortunately, this entails a lot of time and effort, as well as extremely high costs.

Does a vasectomy reversal work?
Vasectomy reversal operations are more successful if they are done fairly soon after the original vasectomy.

About 8 out of 10 men father children when their vasectomy is reversed within three years. If 15 years or more have passed since the vasectomy, this success rate falls to about 3 out of 10 men.

It is important to understand that success is not guaranteed. Even if the operation is technically successful, the presence of sperm in your semen doesn’t guarantee that your partner will get pregnant.

There are also certain factors that can affect your result. These include:

the time that has elapsed since your vasectomy
the type of vasectomy being reversed
the type of reversal (eg vasovasostomy or vasoepididymostomy – see below)
a problem with another part of the reproductive system
the presence of sperm antibodies
It may be possible to have a second reversal operation if the first has not restored your fertility, but it is less likely to be successful than a first reversal attempt.

What are the alternatives?
An alternative to a vasectomy reversal is to extract sperm from either your testicle or epididymis and directly inject it into an egg using an intracytoplasmic sperm injection (ICSI). This fertilised egg then needs to be implanted in the woman’s womb. It is generally not as successful as a vasectomy reversal

(and also it is not dangerous)

First make a appointment with a urologist. Many times vasectomies can be reversed without danger. They will be able to give you all of the facts, and other options. It may be possible for them to do a procedure called scrotum sac extraction, this is just what it sounds like, the scrotal sac still holds live sperm which can not reach your vas deferans, because this is the "tube" that carries the sperm to ejaculation, this is what they clip, burn, tie when you have a vasectomy. Sometimes it is possible to extract sperm from the scrotal sac for insemination. Good luck to you and your journey, it may be a long road ahead, but it will be worth it.

I was gonna answer this question, but Jennifer has replied exactly how I would have done! Great minds think alike! Good luck x
