The outcome of surgery is measured in two ways.


Firstly, if sperm is produced meaning the reversal surgery was successful and the vas is now open, known as patency. Literature worldwide suggests patency rates of 70-90%.

Secondly and more importantly success is measured as pregnancies achieved per vasectomy reversal surgical operation. This is obviously the measure couples are seeking.

Success rates vary and the couples’ individual characteristics may contribute. For example, their respective ages. Fertility and pregnancy rates decline with advancing female age as her eggs are as old as she is. Male sperm is always new and fresh. A vasectomy reversal success rate will therefore be dependent on the female partner’s age. At female age 30 compared to female age 45 there will be a significantly higher success rate from reversal. Jeff Frank and David understand these fertility factors extremely well as experts in the field of reproductive medicine and will personalise you chance clearly.


There are many lifestyle contributions to fertility. Smoking for example decreases fertility and for microsurgery reduces success. Stopping smoking before reversal is a key factor. It also has the benefit in terms of health if the operation is successful i.e., a healthier father. (and mother if she stops smoking).

Surgical training and experience.

The better the surgical training and the more operations and years doing microsurgical vasectomy reversals counts for a lot in success. All three doctors have over 20 years’ experience and have training with leaders in this field. David in Dublin and with Dr Rob Woolcott, Jeff with leading Sydney urologist Dr David Golovsky and with trips to the USA to work with famous Dr Sherman Silber in St Louis, and Frank???
