Erection trouble under 40: why it happens and what actually fixes it
Summary: ED is not only an older man's condition: recent estimates and European surveys report it in a substantial share of men under 40. The main drivers are performance anxiety, porn-shaped expectations and lifestyle, not broken plumbing. Lifestyle changes and treating anxiety come first, with a PDE5 inhibitor such as sildenafil where a doctor judges it appropriate.

Premature ejaculation: causes, types and treatment options
Summary: Premature ejaculation is either lifelong, present since the first sexual experiences, or acquired later, often through stress, anxiety or ED.

A doctor can help identify which type you have and which treatment fits.

Kamagra vs Cialis: how sildenafil and tadalafil differ
Summary: Kamagra (sildenafil) works for about 4–5 hours and Cialis (tadalafil) for up to 36 hours, according to the EMA's product information. Sildenafil is taken for one planned occasion and tadalafil covers a longer window; which suits you is a doctor's decision. Both need arousal and are limited to one dose a day; never take them together, and never with nitrates.

Amoxicillin: uses, dosage and how to take this antibiotic correctly
Summary: Amoxicillin is a penicillin antibiotic for bacterial infections, including chest, ear, sinus, throat, dental, urinary and some skin infections. It does nothing against colds, flu or other viral illnesses. The dose depends on the infection and is set by your prescriber; take it at evenly spaced times and finish the full course, even if you feel better.

What does Viagra actually do? How sildenafil works, explained
Summary: Viagra (sildenafil) blocks the PDE5 enzyme so that blood vessels in the penis stay relaxed during arousal, helping you get and keep an erection. It does not create desire, cause an automatic erection or make you last longer. The EMA product information for Viagra advises taking it about 1 hour before sexual activity.
