Honeymoons and mead
Among other theories for the origin of the word "honeymoon", one that appears frequently is the one that draws on the old (World) tradition of providing the newlywed couple with a month's (one moon) supply of mead. Keep in mind that this was back when people wanted to get pregnant as soon as they were married.
The only source of this with a reference cited that I've found so far was in WASSAIL! In Mazers of Mead (1948) by G. R. Gayre, M.A, D.Sc. on page 22.
Beer-brewing guru Charlie Papazian speculates in The Complete Joy of Home Brewing, 3rd Edition (2003) that the blood-sugar levels may effect the sex of the child conceived. If a male was born, the brewer of the mead was congratulated. This leaves one to speculate what might have happened if it were a female born instead.
