Filter by:Analysis of embryonic cell-free DNA (cfDNA) present in the spent culture media (SCM) is a non-invasive alternative for preimplantation genetic testing for aneuploidies (PGT-A) that avoids the technical challenges and limitations of biopsy. Initial studies investigating this non-invasive PGT-A (niPGT-A) method reported variable concordance between cfDNA in SCM and the trophectoderm sample (~ 30%-86%) and indicated a contribution from both the inner cell mass and trophectoderm to the cfDNA in SCM. This study aims to evaluate the use of the embryo culture medium as a source of genetic material for PGT-A and validate a niPGT-A protocol using cfDNA in SCM.
The purpose of this study is to assess the results of ovarian tissue freezing, such as resumption or initiation of menses (menstruation: the discharge of blood and tissue from the uterus that happens about every 4 weeks in females who are not pregnant) and pregnancy, prior to starting chemotherapy or radiation treatment (commonly used for cancer treatment or for other conditions such as multiple sclerosis, psoriasis, rheumatoid arthritis). Females who are about to undergo chemotherapy or radiation therapy for cancer or these other medical conditions may stop having menses and may not be able to produce a biological child. Girls who have not achieved puberty and are exposed to chemotherapy (alkylating agents) or radiation treatment, the risk is up to 22-50%. In contrast, girls older than 10 years, or who have achieved puberty, experience acute ovarian failure in over 50% of the cases. By freezing and preserving ovarian tissue will help prevent these outcomes. In fact, when you are considered cured of your disease, you will have another surgical procedure where your own ovarian tissue will be transplanted back to you. This surgery will increase the possibility of resuming/initiating menses and the chance to have a pregnancy.
The aim of this study is to track the outcome from the patients who had embryo cryopreservation as part of their Advanced Reproductive Technology (ART) treatment at West Coast Fertility Centers.
The purpose of this study to evaluate a low cost minimal stimulation protocol combined with Intravaginal Culturing, to make IVF affordable and available across the large infertile/subfertile population
