hi, i suggest Dr Michael Wong, a urologist in singapore, who also does vasectomy. he did my husband’s vasectomy and honestly it was a smooth process, and he recovered after a week. this can really help your husband since the whole process was very smooth, and the doctor explained everything clearly before the procedure. I was a little nervous at first, but it turned out to be much easier than i expected. hope this helps, and all the best to both of you!
