It can be physical, psychological or both. Heart disease, diabetes, obesity and age all affect blood flow, and blood flow is what makes an erection. Depression, anxiety and stress can affect mood, desire and satisfaction. Your doctor asks about all of it, because the cause shapes the treatment.

Consults are from $200. You pay for medicine only once a doctor approves it. All medicines add a 3.2% transaction fee. If medicine isn’t right for you, you’re not charged for it.

Better sexErectile dysfunction

ED happens. So does great sex.

Q: What is erectile dysfunction?

Trouble getting or keeping an erection firm enough for sex. It’s common: 51.8% of Hong Kong men have some form of it (Shi et al., 2025).

Q: How do I know if I have ED?

Everyone has an off night, and that’s normal. If it keeps happening, or it’s affecting your relationship or how you feel, it’s worth talking to a doctor. With us, that takes minutes.

Q: Which medicines do you prescribe?

PDE5 inhibitors, the oral treatment Hong Kong’s Drug Office recommends for ED. We carry as-needed pills (sildenafil, tadalafil 20mg and the second-gen pill) and daily ones (tadalafil 5mg), as generics and brands. Your doctor matches one to how you live.

Q: Do ED medicines work?

For most men, yes. Everyone responds a little differently, so your doctor prescribes the medicine and plan most likely to suit you.

Q: Are there side effects?

They can happen. The common ones are flushing, dizziness, headache, an upset stomach, a blocked or runny nose and aches, including back pain. Your doctor goes through them with you.

Q: Can a doctor diagnose ED online?

Yes. A doctor can diagnose it from your medical history and symptoms, by text or video.

A quick chat with a local doctor, by text or video, and treatment at your door in as little as 4 hours. Nobody else needs to know.

Think back over the last six months. How would your partner rate things in the bedroom?

Not a diagnosis. Only a doctor can tell you what’s going on.
