english: To increase the odds of success, which are as high as 40% for a woman younger than 35, doctors sometimes transfer multiple embryos at once, which is why IVF results  in twins and triplets more often than natural pregnancies.
non_english: Da bi se povećale šanse za uspeh, koje idu i do 40% za žene mlađe od 35 godina, doktori nekada ubacuju više embriona odjednom, zbog čega su IVF rezultati sa dvojkama i trojkama mnogo češći nego tokom prirodnih trudnoća.
