Input (Chinese): 英国皇家妇产科学院同意一位代表的观点，他认为同时考虑到这种妊娠难以足月以及妊娠早期发现就终止妊娠的倾向，成功的卵巢妊娠几率“不超过百万分之一”。
Output (English): The British Royal College of Obstetricians and Gynaecologists agrees, with a representative saying the odds of a successful ovarian pregnancy are "no more than one in a million", taking into account both the difficulty of bringing such a pregnancy to term and the tendency for the pregnancy to be terminated when it is discovered early.
