mitochondria and egg quality

The egg cell contains a high number of mitochondria, which are tiny cellular organs that produce energy that the egg needs to power fertilization and embryo development. Research has shown that these mitochondria can become dysfunctional with age, leading to reduced energy availability for the egg that could result in poor egg quality. Different treatments that target mitochondria, like antioxidant supplements or mitochondrial donation, may improve egg quality, although good quality research is lacking that shows these treatments are truly effective.

“True” recurrent implantation failure is rare after five consecutive euploid embryo transfers

Researchers in a 2024 study found that patients that have 5 consecutive euploid transfers had a cumulative live birth rate of 98.1%, suggesting that most cases of implantation failure are due to the embryo, and that true unexplained RIF occurs in less than 2% of patients.

Researchers develop tool to help predict fertilization failure

Researchers in a 2024 study identified what factors were involved in fertilization failure and built a nomogram (calculator) to help predict when this happens, with moderate predictive ability.

Lower cumulative live birth rates with certain forms of endometriosis

Researchers in a 2024 study found lower cumulative live birth rates in patients with a particular type of endometriosis (DIE and/or ovarian endometrioma) that was diagnosed using transvaginal ultrasound.

PGT-A cost analysis for first-cycle transfers across age groups

Researchers in a 2024 study compared the costs of patients with or without PGT-A, finding that patients younger than 35 may not benefit because of the higher chance of top-graded embryos being euploid anyway.
