All patients will be subjected to the following:
-
History taking.
-
Clinical examination (general and local genital examination).
-
International Index of Erectile Function (IIEF-5) before and after treatment (Rosen et al., 2002).
-
Erection Hardness Score (EHS) before and after treatment (Mulhall et al., 2006).
-
Global assessment questionnaire after treatment (Giuliano et al., 2007).
-
All patients will be examined by Duplex Doppler ultrasonography in the basal condition and after the induction of penile erection with the assistance of an intracavernous injection of alprostadil 20 μg/mL.
-
All patients will receive single dose of ICI of 100u of (BTXA) combined with 5mg oral Tadalafil once daily for 3 months.

The subjects will be re-examined and International Index of Erectile Function (IIEF-5), Erection Hardness Score (EHS)and penile color Doppler ultrasound with PGE-1 injection will be done at 6 and 12 weeks from the start of therapy in addition to Global assessment questionnaire will be done at 12 weeks from the start of therapy
* Procedure
- The patients will lied down in supine position. After cleansing the skin with alcohol, intracavernosal injection of single dose 100U (BTX-A) diluted in isotonic saline 2cm proximal to coronal margin at right and left sides will be performed and the injection site will be pressed directly for two minutes.
