Hsu Jenn-jeih, who is one of Taiwan's best known experts about high-risk pregnancies and the director of obstetrics at Chang Gung Memorial Hospital in Taipei, says that older prospective mothers have higher rates of babies with chromosomal disorders largely because their ovaries function worse and the quality of their eggs is uneven. As a result, after eggs are inseminated, problems are more likely to occur during the process of cell division.
國內知名的高危險妊娠專家、台北長庚醫院婦產科主任徐振傑解釋，高齡產婦容易生出染色體異常的寶寶，主要是因為她們的卵巢功能較差、卵子品質較不穩定，這類卵子在受精後的自然分裂過程中容易「凸捶」。
