- 1998 Assisted Reproductive Technology Success Rates
[National Summary and Fertility Clinic Reports]
The 1998 report of pregnancy success rates is the fourth report to be
issued under the Fertility Clinic Success Rate and Certification
Act. The report includes a national report that uses information
from 360 U.S. fertility clinics to provide an in-depth national
picture of ART; fertility clinic tables that provide ART success
rates for each clinic that submitted and verified its 1998 data; and
appendices containing a glossary of terms and lists of reporting and
nonreporting clinics in the United States.
- Contribution
of Assisted Reproductive Technology and Ovulation-Inducing Drugs to
Triplet and Higher-Order Multiple Births— United States,
1980–1997.
Pregnancies associated with assisted reproductive technology (ART) and drugs that induce ovulation are more likely to result in multiple births than spontaneously conceived pregnancies in the United States. Triplet and higher-order multiple births are at greater risk than singleton births to be preterm, low or very low birth weight, which may result in higher
infant morbidity and mortality. This report estimates the connection
between these birth outcomes and ART and ovulation-inducing drugs in
1996 and 1997. It also summarizes the trends that indicate ART and
the use of ovulation-inducing drugs have increased the ratio of
triplet and higher-order multiple births during the 1980s and most
of the 1990s. [Source: MMWR, June 23, 2000/ 49(24);535-8.]
- Live-Birth Rates and Multiple-Birth Risk Using In Vitro
Fertilization
To maximize birth rates, physicians who perform in vitro fertilization (IVF) often transfer multiple embryos, but this increases the multiple-birth risk. Live-birth and multiple-birth rates may vary by patient age and embryo quality. One marker for embryo quality is cryopreservation of extra embryos (if embryos are set aside for cryopreservation, higher quality embryos may have been available for transfer). The study found that, the risk of multiple births from IVF varies by maternal age and number of embryos transferred. Embryo quality was not related to multiple birth risk but was associated with increased live-birth rates when fewer embryos were transferred. [Source: JAMA. 1999;282:1832-1838.]
- Implementation of the Fertility Clinic Success Rate and Certification Act of 1992: A Model Program for the Certification of Embryo Laboratories
A Model Program for the Certification of Embryo Laboratories The Fertility Clinic Success Rate and Certification Act of 1992 (Pub. L. 102-493, 42 U.S.C. 263a-1 et seq.) required the Secretary, Department of Health and Human Services, through the CDC, to develop a model program for
the certification of embryo laboratories, to be carried out
voluntarily by interested states. This notice sets forth the model
certification program requirements, including definitions,
administrative requirements, and embryo laboratory standards. The
model program incorporates comments received by CDC on the proposed
model certification program that was published in the Federal
Register on November 6, 1998 (63 FR 60178). From the Division of
Laboratory Systems, Public Health Practice Program Office,
