Name of IVF centre( ) Contact person : ( ) Name Address Tel Fax All data relate to treatment cycles that were started during the calendar year, 997, and to any clinical pregnancies resulting from those treatment cycles. Please complete as many data items as possible (n = number). If data are not available for some items, write NA. Gestational age (duration of pregnancy) should be calculated by adding days ( weeks) to the number of completed weeks between the date of fertilization (conception) and the date of completion of the pregnancy In the following tables :. IVF includes those treatment cycles and pregnancies in which fertilization occurred, or was intended to occur, in the laboratory and fresh embryos were transferred to the uterus or fallopian tubes. This heading excludes : () frozen/thawed embryo transfer cycles ; and () microinsemination techniques.. ICSI includes those treatment cycles and pregnancies that follow transfer of fresh embryos after intracytoplasmic sperm injection. Transfer cycles after both ICSI and embryo freezing are recorded separatedly.. GIFT includes only those cycles and pregnancies in which gametes (oocytes and sperm) were transferred to the fallopian tubes (excluding combined IVF and GIFT in the same cycle, which should be recorded in IVF category).. Any cycles in which frozen/thawed embryos were transferred should be excluded from Tables,, and 3. Pregnancy outcomes after transfer of thawed embryos should be excluded from Tables, 5, 8 and 9.. Oocyte donation cycles and pregnancies should be included in Tables 3,, 5, 8 and 9, and in Table if frozen/thawed embryos were transferred.. Maternal age refers to age at the start of the treatment cycle. If you did not perform IVF practice in 997, check here. Not done If you performed IVF practice in 997, please fill out tables below. - 56 -
