IVF with Donor Sperm (Long Protocol): What You Need to Know

IVF with donor sperm on the long protocol combines donor sperm with a pre-treatment phase before stimulation begins. A nasal spray (Synarela) is used for approximately 20 days to suppress the body's natural hormone production before stimulation injections start.

Long protocol vs. short protocol

The short protocol is now the standard approach at Klinikk Hausken for the vast majority of patients — including those using donor sperm. It begins stimulation directly at the start of the menstrual cycle without a pre-treatment phase, and is equally effective for most patients with a simpler schedule. For international patients, this is almost always the more practical option.

The long protocol is occasionally recommended in specific clinical situations. If your doctor has indicated the long protocol is appropriate for you, your nurse will explain the differences in detail during your treatment planning appointment.

What to do next

For most international patients using donor sperm, the short protocol is the relevant starting point. Read the full step-by-step guide below, then book a free case review to confirm which protocol suits your situation.
