Some Women Prolong Breastfeeding or Lactation in General as a Form

question 85

Multiple Choice

Some women prolong breastfeeding or lactation in general as a form of birth control. How would extension of lactation be effective in preventing pregnancy?

• A)Lactation stimulates production of placental lactinogen, which is a pregnancy hormone and prevents the corpus luteum from degrading and advancing the reproductive cycle.
• B)Prolactin is the hormone that corresponds with lactation. It also inhibits ovulation at the pituitary gland level, so as long as lactation is actively occurring, ovulation is prevented.
• C)Breastfeeding stimulates production of oxytocin, which causes the endometrium to slough off and exit the body in a menstrual period, preventing implantation of a zygote.
• D)The physical stimulation of breastfeeding causes high levels of progesterone to be produced, which cause secretions in the reproductive tract that are hostile to sperm.
