Multiple births conceived by assisted reproductive technology in Korea

PurposeThe recent trends of multiple births (MBs) conceived by assisted reproductive technology (ART) in Korea were analyzed as well as the relationship with maternal age, especially advanced maternal age.MethodsData were obtained from the Korean Statistical Information Service and annual ART reports from the ART committee of the Korean Society of Obstetrics and Gynecology.ResultsMBs increased from the early 1990s; there was a 275% increase by 2008. The number of total live births was 448,153 and MBs accounted for 10,767; the MB rate was 24.0% in 2006. Among 2,326 deliveries conceived by ART, multiple deliveries accounted for 786 (33.8%). The total number of live births with ART was 3,125 and 1,585 (50.7%) of them were MBs. During 2006, 14.7% of the entire MBs in Korea were associated with ART. The proportion of women of advanced maternal age was much higher in the ART group than in the total live birth group.ConclusionMBs in women of advanced maternal age have been increasing in Korea with the use of ART. The results of this study showed that ART was a significant factor associated with the increase in MBs in Korea

Children born through reproductive donation:A longitudinal study of psychological adjustment

BACKGROUND: Parenting and children’s adjustment were examined in 30 surrogacy families, 31 egg donation families, 35 donor insemination families, and 53 natural conception families. METHODS: Parenting was assessed at age 3 by a standardized interview designed to assess quality of parenting and by questionnaire measures of anxiety, depression and marital quality. Children’s adjustment was assessed at ages 3, 7 and 10 using the Strengths and Difficulties Questionnaire (SDQ). RESULTS: Although children born through reproductive donation obtained SDQ scores within the normal range, surrogacy children showed higher levels of adjustment difficulties at age 7 than children conceived by gamete donation. Mothers who had kept their child’s origins secret showed elevated levels of distress. However, maternal distress had a more negative impact on children who were aware of their origins. CONCLUSIONS: The absence of a gestational connection to the mother may be more problematic for children than the absence of a genetic link
