Higher temperatures, lack of rain and sunshine improved results all the way through fertility treatment - right through to having a baby. The link with sunshine was the 'most striking', with sunny weather increasing the odds of IVF success by 35 per cent the, European Society of Human Reproduction and Embryology's annual conference in Lisbon heard.
Dr Vandekerckhove, of University Hospital Ghent, said sunshine a month before conception is likely to help a woman's eggs mature.
This could be by raising levels of vitamin D, which is made when sunlight hits the skin, or by altering levels of melatonin, the hormone that helps us sleep but is also involved in regulating a woman's reproductive cycle.
Although his study was of IVF patients, he said there is no reason to think that a burst of sunshine won't also help women trying to get pregnant naturally.
He said that in a world where reproduction is becoming increasingly medicalised, sunshine could be a simple way of boosting fertility.
Professor Charles Kingsland, of the Hewitt Fertility Centre at Liverpool Women's Hospital, said: 'We get bogged down and seduced into thinking that in order to get pregnant we need to be taking various pills, potions and creams to aid our fertility when often all that is need are the basics; namely, good diet, no smoking, reduction in alcohol, relaxation, sunshine and being happy and positive.'
