Is "reversal vasectomy" Halal or Haram?

Praise be to Allah, the Lord of the World; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

Vasectomy is forbidden, it could be done only at the time of pressing need since it causes sterility and prevents progeny that is contrary to the aims of Shari'a. Islamic Sharia urges Muslims to increase their progeny and considers it a great blessing of Allah. There are many proofs in Sharia that support this fact.
However, reversal vasectomy is permissible since uncovering Awrah at the time of necessity is permissible. No doubt, the need of giving birth is a valuable necessity in Islamic Sharia.
Allah knows best.
