Meaning that opportunity is more likely to present itself. (In Ireland, March is also, statistically, a popular month to give birth – and these babies would have been conceived slap bang in the middle of summer holidays – when, of course, people are off from work and have time to get down to baby making business).

A study exploring the correlation between seasonal changes and conception concluded that sperm quality is often deteriorated during the summer, with changes in daylight length also affecting the anterior pituitary-ovarian function, the variation in quality of the ovum or endometrial receptivity.
