Fertility clinics can apply to re-open from May 11 as long as they ensure the safety and protection of staff and patients, the Human Fertilisation and Embryology Authority said.
Treatment had been suspended because of the coronavirus outbreak.
All clinics, whether NHS or private, will need to have social distancing in waiting rooms and use telephone appointments where suitable.
Health Secretary Matt Hancock said: “Now that we are past the peak, I am delighted to announce the restoration of fertility services.
“People who are relying on fertility treatment have been worried during these unprecedented times not knowing when they could continue their journey to start a family.
“We wanted to open these clinics as soon as it was safe to do so, and our strict guidelines will ensure staff and patients remain safe as we continue to tackle this virus.”
