The study, titled “Better than nothing or savvy risk reduction practice? The importance of withdrawal,” appears in the June edition of the journal Contraception, reports CBS News.
The authors find: “If the male partner withdraws before ejaculation every time a couple has vaginal intercourse, about 4 percent of couples will become pregnant over the course of a year.
“However, more realistic estimates of typical use indicate that about 18 percent of couples will become pregnant in a year using withdrawal.
“These rates are only slightly less effective than male condoms, which have perfect- and typical-use failure rates of 2 percent and 17 percent, respectively.”
