This phrase refers to an ovulation calculator designed to purportedly increase the chances of conceiving a male child. The premise suggests that timing intercourse around ovulation, based on certain theories about sperm motility and the survival rate of sperm carrying X or Y chromosomes, can influence the sex of the offspring. For example, some methods advocate having intercourse closer to ovulation to favor the faster-swimming Y-chromosome sperm.
The perceived importance of such a tool stems from cultural or personal preferences for having a son. Throughout history, in various societies, having a male child has been associated with continuing the family lineage, carrying on the family name, or providing future economic support. While the desire for a child of a particular sex is a personal choice, it is essential to acknowledge that scientific evidence supporting the effectiveness of these calculators in guaranteeing the sex of a child is limited and often anecdotal.
