Brief Answer:
Erectile Dysfunction need evaluation.

Detailed Answer:
Hi,

Thanks for your question.
Noted your concern.

There may be most likely possibility of Erectile Dysfunction in your case.

Patient can achieve erection but cannot sustain it is one of the initial presenting complaint in Erectile Dysfunction.

It is due to-
- Endothelial dysfunction (abnormality of cell lining of blood vessel of penis).
- Diabetic autonomic neuropathy.

Following are the risk factors for developing Erectile Dysfunction-
1) Diabetes.
2) Blood pressure.
3) Cholesterol problem.
4) Hormonal imbalance.

In such scenario I may suggest -
- Detailed physical examination.
- Investigations-
Complete Blood Count
Renal Function Test.
Liver Function Test.
Lipid Profile.
HbA1c.
T3, T4, TSH.
Serum Testosterone level.

So it will be better to consult endocrinologist/ diabetologist for detailed clinical examination and further evaluation and appropriate treatment.

Medicine like Sildenafil or Tadalafil can be useful but before using it you should consult endocrinologist/ diabetologist as they are prescription medicines and also requires cardiac evaluation before starting it.

Hope I have answered your question.

Regards,
Dr. Abhay Mali.
Diabetologist.
