Following is the wordings of His Excellency:In the Armed Forces Hospital, we receive questions (Part No. 24; Page No. 436) regarding the ruling on masturbation in a hospital laboratory for the purpose of performing sterility tests. As the sample should be delivered to the laboratory within ten minutes after ejaculation; otherwise it will be useless.
