Rasedad naised ei peaks sünnituse eeldatavat kuupäeva liiga tõsiselt võtma, sest aeg, millal laps on emaüsas, võib kõikuda 37 päeva võrra, selgub uurimusest, mille avaldas veebis ajakiri Human Reproduction.Uurimus näitas, et ainult üks naine kahekümnest sünnitab täpselt 280 päeva või 40 nädalat pärast lapse eostamist. Tegelikult võib rasedus kesta 37-st 42 nädalani, vahendab ERR uudisteportaal Daily Maili.

„Me leidsime, et keskmine aeg ovulatsioonist sünnini oli 268 päeva – 38 nädalat ja kaks päeva,“ ütles USA riikliku keskkonnahügieeni instituudi epidemioloogia osakonna aspirant doktor Anne Marie Jukic.

Vanemaealised naised sünnitavad keskmisest hiljem, kusjuures iga eluaasta lisab raseduse kestusele keskmiselt ühe päeva.
