68 / 100
Mostly True

The text claims that sucking on a female's nipples can cause irregularities in periods and is an unreliable contraception method. It states that this action releases prolactin, making the body think there is a suckling infant, which may delay the next period.

Infact verdict: Mostly True (68/100).

The claims regarding nipple stimulation and its effects on hormonal changes and menstrual cycles have varying degrees of support. The claim that nipple stimulation can cause irregular periods is supported by evidence indicating hormonal changes can occur, particularly during breastfeeding. However, the claim that nipple sucking is a method of contraception is misleading, as it is not a reliable method. Prolactin release due to nipple stimulation is well-documented, and it can signal the body to produce milk, simulating the presence of a suckling infant. High prolactin levels can delay periods by suppressing ovulation, but this is not a consistent or reliable contraceptive method.
