This study investigated the quality and quantity of eggs and embryos as well as the clinical pregnancy outcome in young infertile women with diminished ovarian reserve (DOR) after in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).
MATERIAL AND METHODS: We retrospectively reviewed records of 4285 infertile women and divided them into 3 groups according to age and ovarian reserve: young women with normal ovarian reserve (n=1695), young women with DOR (n=1121), and older women with DOR (n=1469).
RESULTS: In young women with DOR, the proportion of high-quality embryos was significantly higher than in older women with DOR and lower than in young women with normal ovarian reserve (P<0.01). The proportions of ovulation cancellation, ovulation without egg acquisition, and ovulation without available embryos in young women with DOR were significantly higher than in young women with normal ovarian reserve. The rates of biochemical pregnancy, clinical pregnancy, and embryo implantation in young women with DOR were significantly higher than in older women with DOR, and lower than in young women with normal ovarian reserve. The miscarriage rate was 19.17% in young women with DOR, significantly lower than in older women with DOR (33.90%), and higher than in young women with normal ovarian reserve.
CONCLUSIONS: Young women with DOR have ovarian hypo-response and low numbers of acquired eggs and embryos, but the possibilities of high-quality embryo and good clinical pregnancy are higher once eggs are acquired. The indications to IVF/ICSI can be widened and active treatments should be administered for these women.
