description Objective: This study was carried out to compare the clinical outcome of elective single cleavage-embryo transfer (eSCET) to that of elective single blastocyst-embryo transfer (eSBET) in human IVF-ET. Methods: This study was a retrospective study which analyzed for 614 women who visited the Daegu Maria Clinic from August 2008 to December 2009. All were under 37 years old and had more than 8 mm of endometrial thickness on the day of hCG administration and at least one good quality embryo on day 3. The eSCETs were performed on day 3 (n=450) and the eSBETs were conducted on day 5 (n=164). Results: The numbers of retrieved oocytes, fertilized oocytes, and day 3 good quality embryos were significantly lower in the eSCET group (12.1${\pm}$6.0, 8.2${\pm}$4.6, and 4.2${\pm}$3.1, respectively) compared to the eSBET group (16.7${\pm}$7.2, 12.1${\pm}$5.0, and 8.5${\pm}$4.5, respectively; p

However, the clinical pregnancy, implantation, on-going pregnancy, and live birth rates of the eSCET group (46.7, 46.9, 40.0, and 36.7%, respectively) were not statistically different from those of the eSBET group (51.2, 51.8, 45.1, and 43.9%, respectively; p=0.318, 0.278, 0.254, and 0.103, respectively). Conclusion: These results suggested that elective single embryo transfer should be performed regardless of the developmental stage to women less than 37 years old who had more than 8 mm of endometrial thickness on the hCG administration day and at least one good quality embryo on day 3 in order to reduce the twin pregnancy rate without reducing the whole pregnancy rate.</description><identifier>ISSN: 2233-8233</identifier><identifier>EISSN: 2233-8241</identifier><language>kor</language><ispartof>Clinical and experimental reproductive medicine, 2011, Vol.38 (1), p.53-60</ispartof><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,314,780,784,885,4024</link.rule.ids></links><search><creatorcontrib>Kang, Sang-Min</creatorcontrib><creatorcontrib>Lee, Sang-Won</creatorcontrib><creatorcontrib>Jeong, Hak-Jun</creatorcontrib><creatorcontrib>Yoon, San-Hyun</creatorcontrib><creatorcontrib>Lim, Jin-Ho</creatorcontrib><creatorcontrib>Lee, Seong-Goo</creatorcontrib><title>Comparison of elective single cleavage-embryo transfer to elective single blastocyst-embryo transfer in human IVF-ET</title><title>Clinical and experimental reproductive medicine</title><addtitle>Clinical and experimental reproductive medicine : CERM</addtitle><description>Objective: This study was carried out to compare the clinical outcome of elective single cleavage-embryo transfer (eSCET) to that of elective single blastocyst-embryo transfer (eSBET) in human IVF-ET.
