Assisted hatching in cryopreservation protocols in patients with tuboperitoneal infertility

At present, the problem of increasing effectiveness programs assisted reproductive technologies and successful infertility treatment is still relevant. Assisted hatching used in devitrificated embryo transfer facilitates exit from pellucide zone. Yet clinical efficacy relevant debatable. There are no clear indications for use this technology, groups patients have been identified. The aim study. To assess laser frozenthawed with tuboperitoneal infertility. Materials methods. We examined 300 women who had their embryos frozen transfer. Inclusion criteria: age 18 to 35 years; infertility; cryopreserved Exclusion more than 36 other factors. Women were divided into 2 groups: group 1 – a frozen-thawed preliminary (n = 137); control 163). Results. differences between mean age, body mass index at menarche. According results embryological stage, there also number quality embryos. pregnancy rate was 44.5 %, which significantly higher (42.3 %; р ≤ 0.001). found statistically significant outcomes: frequency spontaneous miscarriages 13.1 % 20.2 respectively (p 0.001), term deliveries 30.7 22.1 Conclusion. In our study, using positively affected implantation cryopreservation protocols. Pregnancy live birth rates after up 12 weeks lower. This provide an opportunity further study effect on long-term outcomes, such as gestation course childbirth.
