Filter by:Patients with infertility of the older age group of 37-42 years - a large cohort of patients of reproductive medicine. Two possible causes reduce their probability of pregnancy - an increasing age and a decrease of the ovarian reserve. In these conditions, the early receipt of embryos for future transfer can serve as a correct strategy for treating infertility in this category of patients. According to statistical data, patients of the 37-42-year-old age group need 3-5 blastocysts, out of them 1-2 euploid to achieve pregnancy. The POSEIDON group of researchers identified a group of 2b patients with a suboptimal response to the induction of superovulation in IVF programs - patients older than 35 years with a normal ovarian reserve (the number of antral follicles greater than 5 and Anti-Müllerian hormone (AMH) greater than 1.2 ng / ml), resulting in 4-9 oocytes after a standard ovarian stimulation. In this situation standard stimulation protocols can stretch the process of obtaining embryos indefinitely, during which the patient will move to another age category with a decrease in the likelihood of pregnancy. Thus, these patients are shown the fastest reception of oocytes and the accumulation of embryos, which can be done using double ovarian stimulation in the same menstrual cycle. The aim of the study is to compare the different schemes of double stimulation in patients with infertility of the older age group of 37-42 years with the preceding suboptimal response. Group 1 - patients of the DUOSTIM group. Group 2 - Patients of the Shanghai Protocol. The investigated parameters - primary outcome measures: total number of retrieved oocytes per cycle, secondary outcome measures: total number of blastocyst per cycle, number of cycles with double ovarian stimulation required to obtain 3-5 blastocyst, time until embryo transfer, pregnancy rate and birth rate This is a prospective randomized non-blinded clinical study.
The main purpose of the study is to assess the impact of environmental conditions on live-birth rates after intraconjugal IVF. The second purposes are - to assess the impact on pregnancies (prematurity, preeclampsia); - to assess the impact on newborn's health (stunted growth); - to evaluate the consistency of results observed between assisted pregnancies and spontaneous pregnancies.
