A tool exists that estimates potential conception dates and calculates the likelihood of paternity when two men could be the father. This assessment method utilizes reported dates of sexual intercourse and considers the typical window of female fertility. For example, if a woman had intercourse with two different partners within a week, this method can provide a probability percentage for each man being the biological father.
This estimation method can offer clarity in uncertain situations and provide valuable information for individuals seeking to understand possible parentage. Historically, determining paternity relied on blood typing and similar methods; this type of calculation offers a non-invasive preliminary assessment. It serves as a starting point before potentially pursuing definitive DNA testing.
