Abstract
Successful pregnancies and deliveries are rare in women over 40 years of age. To date, no case report has been published about a successful delivery in a woman over 40 years of age using vitrified oocytes obtained through social egg freezing from a woman over 40 years of age. Here we report a case of a successful live birth from a 44-year-old woman using vitrified oocytes taken from the woman at 41 years of age; the patient used the technique for social reasons. The 44-year-old patient delivered a 2534 g female infant by Caesarean section in the 37th week of pregnancy. The female infant’s Apgar scores were 9 at 1 min and 9 at 5 min. The female infant exhibited no anomalies and is developing normally under the close surveillance of pediatricians.However, the concept of social egg freezing has medical, ethical and social problems. Furthermore, the rate of live births differs among clinics and/or hospitals due to variations in the vitrification and warming techniques used. Therefore, information from individual clinics and/or hospitals about the risks, the rates of successful live births and the cost of social egg freezing should be provided to patients to aid in the patient’s decision-making process.

Summary
Given the advancement in technology for human egg freezing, the use of social egg freezing is increasing in developed countries[1,2]. No case report about a successful delivery from a woman over 40 years of age using vitrified oocytes obtained through social egg freezing from a woman over 40 years of age has been published to date (as assessed through a PubMed database search). The patient was a 41-year-old woman who wanted to freeze her eggs for social reasons. In August 2014, an embryo (day 5) from a vitrified oocyte was transferred to the uterus (the endometrium thickness: 7.5 mm), and the patient’s pregnancy was confirmed by the presence of a GS at 5 weeks (Figure 1). The 44-year-old patient delivered a 2534 g female infant by Caesarean section in the 37th week of pregnancy in May 2015. The female infant exhibited no anomalies and is developing normally under the close surveillance of pediatricians
