Open-ended vasectomy was performed on one-hundred men. Sixty-three of them showed up for follow-up six months later. Spontaneous recanalisation had occurred in two. Sperm granuloma without orchialgia was found in 14 out of 59 men (23.9%). Twenty-one out of the 63 thought their sex life had improved, while 40 thought it was unchanged; only one man mentioned pain during intercourse since vasectomy.
