The application of preimplantation genetic testing (PGT) began in the late 1980s. Pre-implantation genetic testing, as the earliest possible method of prenatal diagnosis, enables the selection of embryos with a normal karyotype for embryo transfer. The use of preimplantation genetic testing has proven to be a useful method in the following three groups of inherited diseases: monogenic disorders (single gene defects), trinucleotide repeat disorders, and chromosomal abnormalities. The success rate of in vitro fertilization (IVF) has increased significantly since the introduction of PGT into clinical practice. This paper presents a literature review with the aim of clearly determining the role of PGT in embryo selection before embryo transfer, as well as the role of this type of testing in increasing the success rate of IVF. One of the goals of the paper is also to review the development of molecular genetic methods that are currently, or have once been, in routine use when performing PGT. The current literature is an indicator of the development and progress of molecular genetics techniques applied in PGT. At the same time, it provides an opportunity and an incentive for further extensive research that will lead to the improvement of preimplantation genetic testing and thus increase the success rate of in vitro fertilization.

AbstractObjectiveTo determine the role of Anti-Mullerian Hormone (AMH) in predicting fertilization and pregnancy rates following in vitro fertilization-embryo transfer (IVF-ET) and intracytoplasmic sperm injection (ICSI) treatment cycles.MethodsThis was a prospective cohort study of one hundred and fifty consecutive women undergoing IVF-ET/ICSI that were recruited from February 1, 2017 to October 31, 2018 at the Fertility centre of the National Hospital, Abuja, Nigeria. Participants’ plasma AMH were assayed and were followed up till achieving fertilization and pregnancy. Association between AMH levels, fertilization and pregnancy rates was assessed using univariable and multivariable logistic regression modelling to adjust for confounding variables.ResultsThe mean age and mean AMH level of the participants were 36 ± 4.2 years and 1.74 ± 2.35ng/ml respectively. There was a statistically significant association between AMH level and age (P <0.001), duration of infertility (P =0.026), cause of infertility (P =0.035), number of oocytes retrieved (P =<0.001), number of embryos generated (P =<0.001) and type of treatment (P =<0.001). However, there was no significant difference in the fertilization rates (adjusted odds ratio [AdjOR] 0.36, 95% confidence interval [CI] 0.23–4.30; P =0.533) and pregnancy rates (AdjOR 0.26, 95% CI 0.04–2.00; P =0.210) at different plasma levels of AMH.ConclusionPlasma AMH level was not a predictor of fertilization and pregnancy rates among our cohort of patients who had IVF/ICSI treatment cycles.
