    en.wikipedia.org/wiki/Preimplantation_genetic...

    There are three distinguished types of Preimplantation Genetic Testing (PGT) depending on the defects evaluated. PGT-A, also called preimplantational genetic screening (PGS), improves pregnancy rates by allowing the discard of aneuploids and the selection of euploid embryos for transfer. Euploid embryos are more likely to implant and develop ...

    In a survey of the North American embryo transfer industry, embryo transfer success rates from direct transfer of embryos were as good as to those achieved with glycerol. [58] Moreover, in 2011, more than 95% of frozen-thawed embryos were transferred by Direct Transfer. [59]

  4. Pregnancy rate - Wikipedia

    Pregnancy rate is the success rate for getting pregnant.It is the percentage of all attempts that leads to pregnancy, with attempts generally referring to menstrual cycles where insemination or any artificial equivalent is used, which may be simple artificial insemination (AI) or AI with additional in vitro fertilization (IVF).

    The success rate of reciprocal IVF heavily depends on the age of the birth mother. For women under age 35, there is a 41-43% success rate. For women over 40, there is a 13-18% success rate. [21] As IVF is not always successful on the first attempt, it is important that couples understand that multiple cycles may be required to achieve a ...

    A normal division rate is to double cell number each 24 hours. A higher rate implies chromosomal abnormalities and a lower rate entails possible embryo arrest (it is dying). Fragmentation: happens due to cell apoptosis and can be quantified by the % of the embryo total volume eccupied by fragments. Fragments are cytoplasm fractions without nuclei.

    As a result of the 1992 Fertility Clinic Success Rate and Certification Act, the CDC is required to publish the annual ART success rates at U.S. fertility clinics. [29] Assisted reproductive technology procedures performed in the U.S. has over than doubled over the last 10 years, with 140,000 procedures in 2006, [30] resulting in 55,000 births ...

  8. Maternal effect - Wikipedia

    en.wikipedia.org/wiki/Maternal_effect

    In genetics, a maternal effect occurs when the phenotype of an organism is determined by the genotype of its mother. [1] For example, if a mutation is maternal effect recessive, then a female homozygous for the mutation may appear phenotypically normal, however her offspring will show the mutant phenotype, even if they are heterozygous for the mutation.

    A recent clinical trial showed a sharp reduction in miscarriage with embryos derived from PICSI sperm selection. [23] 'Washed' or 'unwashed' sperm may be used in the process. Live birth rate are significantly higher with progesterone to assist implantation in ICSI cycles. [24] Also, addition of a GNRH agonist has been estimated to increase ...
