The experience of prenatal diagnosis and termination of pregnancy can be an unwelcome memory and this leads to a demand for an alternative approach. Our data suggest that PGD is acceptable to patients and is a valuable alternative to prenatal diagnosis.

Purpose: To present a case describing the birth of a healthy female after the replacement of vitrified biopsied embryos after Preimplantation Genetic Diagnosis.Method: A descriptive case report of a single patient.Results: Our patient carrier of an X-linked disease became pregnant and as a result a healthy girl was born.Conclusions: This report shows that blastocysts obtained from biopsied embryos can be successfully cryopreserved by a simple, secure and low-cost vitrification method using a Hemi-straw support.

Research in the field of preimplantation genetic diagnosis (PGD) has concentrated on increasing the number of diseases diagnosed, different strategies for single cell analysis and improving efficiency and reliability. Of equal importance are clinical issues such as the demand for and cost of PGD. This study assesses patient awareness of PGD and its potential benefits; additionally the awareness, attitudes and referral patterns of Assisted Conception Units, Regional Genetics Centres and Health Authorities (funding bodies) have been analysed to establish the demand for PGD within the United Kingdom. The licensed units are able to perform 128 cycles of PGD annually, however 256 cases were referred within the last year. It is clear that the currently licensed units operating at their present capacity are unable to meet the demand for PGD in the U.K. Concerns raised by this study include the unequal geographical distribution of PGD services and the lack of a uniform funding policy by Health Authorities. The investment in personnel and technology to establish a PGD service is considered and a costing provided. We estimate an initial investment in the region of 139,000 Pounds with annual running costs of 55,000 Pounds. This information should contribute towards an appropriate allocation of resources at a national level in the U.K.
