Some women do not grow enough eggs so 58 (8.5%) did not have an embryo transfer.

Couples are encouraged to have only 2 embryos transferred because of the high risk of complications of multiple pregnancy.  In 2007, 99.8% of couples at this unit had 1 or 2 embryos transferred.  Despite this, 18.2% of the clinical pregnancies were multiple.
