30% of women 'able to conceive naturally after infertility treatment'

27 July 2016

A new UK study indicated that around one-third of women who undergo infertility treatments are then able to go on to conceive naturally.

Led by Imperial College London, the research contacted users of an independent fertility website asking members who had received in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) treatments to participate in an anonymous survey.

From the 403 applicable responses, they found that of the 96 respondents who did not conceive through the course of the treatments, 34 subsequently conceived within six years of the cessation of treatments, leading to 30 live births.

Of the 307 who conceived during the treatments, 84 also conceived post-treatment. 87 per cent of the spontaneous conceptions occurred within two years of finishing the infertility treatments, and over the six-year period following treatments 22 per cent delivered a live baby.

Lead author Samuel Marcus said: "Regardless of the outcome of IVF and ICSI treatments - whether the patients conceived or not - there is about a 30 per cent likelihood of conceiving over a six-year period."

However, it was noted that since the study relied on self-reporting, a selection bias may have been caused by pregnant couples being more willing to respond than those who were disappointed.
