Three months after a vasectomy reversal and I still have 0 sperm count. Is there a chance the sperm will return soon?

It takes about three to four months for the testicle to begin producing sperm again after a reversal. It would be more encouraging if there were some sperm seen as this would assure patency i.e. the procedure worked. As it is we don't know if the repair failed or that the testicles have "picked up the ball" so to speak and begun producing sperm. I'd recommend a repeat semen analysis at six months. Time will tell and yes there is hope. I have had patients with minimal numbers of sperm at one year and pregnant at two years.

Very unlikely sperm will return if a vasovasostomy was performed on at least one side and sperm were found in the vas on at least one side. If a bilateral vasoepididymostomy was performed, occasionally it can take up to 9 months for sperm to return. But even then usually some sperm are seen in the ejaculate at 3 months. Success of repeat reversal in the hands of an experienced microsurgeon is excellent, especially if sperm were found in at least one vas.

By 4 months post-reversal, I would be concerned if I saw no swimming sperm. It can be redone and/or a sperm harvest could be done, but then you would have to proceed with IVF.

Yes, there is a chance the sperm will return. Ask your doctor about a one month course of anti-inflammatories.

After three months, no sperm seen? Highly unlikely that the reversal will be successful but it is possible, so you should continue to obtain semen examinations.
