Well, an old lover's tale has received scientific backing, if only in part. New Aussie statistics seem to have confirmed that summer loving leads to more babies in spring.
While June is a popular month to make love, the same holds true for the months of October, November, December and January, according to new figures.
Figures suggest that Aussies conceive more in October and November and, also in June and July-when nights get longer and quilts get warmer.
Historical birth data collated by the Offices of Births, Deaths and Marriages in NSW and Victoria revealed that there were about 10 per cent more births in July, August, September and October and increasingly higher numbers around February and March.
While the figures point to a more traditional mating season that begins in spring, they also challenge astrologers, who presume there are equal numbers of people born under each star sign.
The research revealed that maternity wards are often busier in spring.
Pam Tytler, from the birthing suite at the Northern Hospital in Melbourne, said that they often hired more staff in September and October.
Last year, the unit delivered 183 babies in October against 141 in December.
The researchers collated overall data from total births in 1958, 1983 and 2008 in NSW and Victoria.
Dr Christine Read, the medical director of Family Planning NSW, said that the figures were intriguing and raised questions about whether birth times were planned or followed more instinctive or seasonal patterns.
