Researchers in Denmark looked at 5,594 men and 5,342 women born between 1984 and 1987 and followed them to adulthood until the end of 2017.
They found that men who had been born with a lower than average weight had a 55 per cent increased risk of infertility compared with men born within the normal weight range at birth.
They found no link between gestational age and infertility in women.
The research, published in the journal Human Reproduction, found 8.3 per cent of the men born small for their gestational age had been diagnosed or were being treated for infertility, compared with 5.7 per cent of men born within the normal weight range.
