Efficiency of Comprehensive Chromosomal Testing of Trophectoderm Biopsies of Blastocysts in In Vitro Fertilization

Preimplantation embryo aneuploidy is a major source of adverse outcomes in human reproduction since it leads to implantation failure, early pregnancy loss or severe chromosomal diseases. The risk of embryos aneuploidy is drastically increased after 35 years old. The intra uterine transfer of euploid embryos assessed through such techniques as next-generation sequencing (NGS) based Comprehensive chromosomal Testing of Trophectoderm (TE) biopsies of Blastocysts (CTTEB), may improve implantation and live birth rates, and decrease miscarriage rates. But no randomized controlled trial (RCT) was ever performed to test the interest of CTTEB for women that really needed it (?35 to ? 41 years old). In this multicentre randomized-controlled-trial, the investigators will compare live birth rate obtained after the first single frozen-thawed blastocyst transfer cycle following the freeze-all-Intracytoplasmic sperm injection cycle in infertile and old couples between two different strategies of Day 5/6 blastocyst selection: Control group: morphological criteria (Istanbul consensus) Interventional group: international recommendations after CTTEB (www.pgdis.org; Newsletter May 27, 2019).

Impact of Meditation and Reiki on Assisted Reproduction Techniques Outcomes

Infertility is estimated to affect 15% of reproductive age couples worldwide and is defined as the inability to conceive after 12 months of unprotected sex for women under 35 or 6 months for women over 35 and is associated with stress, especially due to psychological factors such as anxiety, frustration and depression. In addition, women seeking treatment for pregnancy suffer additional stressors - significant emotional burdens and physical changes that can increase stress and anxiety levels. The possibility of an association between emotional stress and pregnancy outcome in women undergoing assisted reproduction treatment makes important therapies that address the psychological state of these women. Meditation and Reiki have been used to successfully reduce stress and anxiety in various health contexts. Reiki is a complementary health approach in which practitioners lightly place their hands on or just above a person to facilitate their own healing response. Reiki has been used as an adjunctive therapy to treat the symptoms common to infertile women seeking treatment, including anxiety, stress, depression, anger, despair and depression. Reviews of randomized controlled trials concluded that implementation of the Reiki intervention in health centers resulted in mental health benefits, including reduced tension, mental confusion, anxiety and pain as well as improved quality of life. Meditation can be defined as a form of mental training aimed at improving an individual's psychological capacities, such as attentional and emotional self-regulation. Meditation encompasses a family of practices that include mindfulness meditation, mantra meditation, yoga, tai chi and chi gong. Meditation has been used specifically in women undergoing IVF treatment to successfully reduce symptoms related to psychological distress. Studies measure the development of self-compassion, mechanisms of emotion regulation, and coping strategies related to infertility and quality of life in infertility. However, only one study showed a relationship between meditation and pregnancy rate. Unfortunately, the authors incorporated yoga and psychological approaches into meditation. Therefore, we designed this study to evaluate the impact of Meditation and Reiki on the outcome of assisted reproduction treatment.

Predictive Value of New AMH Test Method for Ovarian Response

In China, the incidence of infertility is about 15%, and patients need to use assisted reproductive technology (ART) to obtain pregnancy. It is particularly important to accurately predict the patient's ovarian response before initiating controlled ovulation hyperstimulation (COH). At present, the commonly used AMH detection method is enzyme-linked immunoassay (ELISA), and it has obtained the normal reference range for ovarian response. In recent years, with the development of detection technology, chemiluminescence immunoassay?CLIA? detection reagents have been successively used for the detection of AMH. However, there are few studies on the comparison of these two detection methods. The predictive value of the new method on ovarian response was lack. Therefore, by comparing the two methods of ELISA and CLIA detection of AMH levels in this study, the predictive value of poor ovarian response (the number of retrieved oocyte ? 3) and high response (the number of retrieved oocyte ? 15) in IVF/ICSI stimulation cycle was analyzed. In order to provide more reference basis for individualized COH, the AMH cutoff value of low and high ovarian response by the new method predicts was analyzed. At the same time, the prediction value of the two methods is compared to determine whether the new CLIA is suitable for clinical application.

PErsonalized Addition of Recombinant LH in Ovarian Stimulation

Different ovarian stimulation regimens have shown to modify late follicular phase hormonal profiles. Besides, recent studies confirm that progesterone levels and their variation in the last day of oocyte maturation are affected by the dose of gonadotropins administered and by other factors. Progesterone elevation in late follicular phase of in vitro fertilization/intracytoplasmatic sperm injection (IVF/ICSI) cycles under ovarian stimulation compromises implantation rates due to a negative effect on the endometrium. However, there is still conflict in the literature questioning whether progesterone levels alone on the triggering day is a sufficient indicator as progesterone does not give the full picture of the ovarian functions, number of follicles as well as estrogen production that facilitate endometrial growth, thus some studies suggest that especially in aged and poor responders Progesterone/Estrogen (P4/E2) ratio has a better reflection (Progesterone (ng/mL) ×1,000/estradiol(pg/mL)) on the ovarian function. The scope of the current pilot study is to compare serum progesterone levels as well as P4/E2 ratio on the day of ovulation triggering of women belonging to POSEIDON category group 2 who undergo a new ovarian stimulation with a dose of rhFSH 300 IU or 300 IU rhFSH plus 150 IU recombinant human luteinizing hormone (rhLH) in a gonadotropin-releasing hormone (GnRH) antagonist protocol.
