Filter by:The aim of this study is to determine the relationship between dietary total antioxidant capacity, phytochemical index, inflammatory index, dietary polyphenol intake and ongoing pregnancy outcome in couples receiving IVF treatment. In this context, the objectives are: Determining the relationship between diet's antioxidant capacity, phytochemical index, inflammatory index, and dietary polyphenol intake and ongoing pregnancy outcome, Determining the relationship between total serum antioxidant capacity, serum oxidant capacity and CRP levels and ongoing pregnancy outcome, It is the determination of the relationship between body composition and ongoing pregnancy. With this study, it is aimed to obtain reliable data on the effects of diet's antioxidant capacity, phytochemical index and dietary polyphenol intake and inflammatory index on reproductive functions. In this way, it is thought that nutritional recommendations that can be given to patients who will undergo IVF treatment before treatment will be developed. In this study, which is a first in terms of examining many parameters related to diets of women and men, it will be evaluated whether the parameters to be examined are effective in IVF cycles. The aims, objectives and hypotheses the researchers put forward within the scope of the study have not been studied extensively before. If the planned project is carried out successfully, new nutritional approaches will be paved in in-vitro fertilization treatment, and it will be possible to contribute to reducing the financial burden of the treatment. In addition, an important step will be taken to increase the total fertility rate (number of children per woman) within the scope of the 11th Development Plan (2019-2023). It also conforms to the 3rd Sustainable Development Goals, "healthy and quality life" (UNDP Turkey 2018)
Transferring an euploid embryo avoids one of the main reasons of miscarriage and implantation failure (1), overcoming confounding factors such as embryo ploidy or maternal age. Frozen Euploid Embryo Transfer (FEET) is routinely performed under standard hormone replacement therapy (HRT) and could be considered the best model for evaluating the impact of the endometrial preparation in clinical pregnancy rate and also in miscarriage rate. Recently several authors have paid attention to serum progesterone (P) as a possible factor influencing Frozen Embryo Transfer (FET) outcomes. P plays an important role in endometrial gland formation, embryonic implantation and pregnancy maintenance. Labarta et al. (2) described in blastocyst FET performed under HRT that serum P <9.2 ng/mL measured on the transfer day is associated to significantly lower ongoing pregnancy rate (OR 0.297, 95% CI:0.113-0.779). Recently the investigators have analyzed 244 FEET performed under HRT in a retrospective study (3). Preimplantation genetic testing for aneuploidies (PGT-A) was carried out as previously described (4). Embryos that reached the blastocyst stage were biopsied and frozen immediately afterwards using the vitrification method (5). Euploid embryos were transferred in a subsequent cycle under HRT. Serum P was analyzed the day previous to FEET. Patients with serum P <10.6 ng/mL had significantly higher miscarriage rate (26.6% vs 9.5%, p=0.007) and lower live birth rate (47.5% vs 62.3 %, p= 0.029) than those with serum P >10.6 ng/mL. The investigators also observed that patients with serum P >13.1 ng/mL had the lowest miscarriage rate (9.1%) and the highest live birth rate (65.6%). The worst outcomes were observed when serum P was <8.06 ng /mL (41% live birth rate and 32.4% miscarriage rate). As miscarriage was higher among FEET cycles with serum P <10.6 ng/ml, the investigators hypothesize that altering the progesterone supplementation scheme could potentially reduce miscarriage rates and increase live birth rate. The purpose of this study is to modify the standard progesterone supplementation in FEET under HRT (vaginal micronized progesterone 200 mg every 8 hours) (6) according to serum P measured not only on the day prior to transfer but also on Beta subunit of Human Chorionic Gonadotropin (β-hCG) analysis day, and to probe if this intervention reduces miscarriage rate and increases pregnancy outcome.
