Filter by:Infertility affects approximately 10-15% of the population. The number of assisted reproduction procedures has increased by a factor of 3 to 5.3 worldwide over the last 20 years. Despite recent techniques, pregnancy rates seem to be limited to 35% by embryo transfer. Embryo implantation depends on two factors: the quality of the embryo and the endometrial receptivity. Although good quality embryos are transferred, implantation may not occur. Changes in the maternal cytokine profile at the time of implantation may result in poor implantation or early abortions. Consequently, a misdirection of the immunological profile could be responsible for repeated implantation failure (RIF). The definition of RIF is not consensual, but most commonly refers to 3 failures after good quality embryo transfer, and would affect between 5 and 10% of patients. The possibility of defining a predictive immune profile for RIF from a peripheral blood sample is debated. However, after stimulation of immune cells in peripheral blood, patients with RIF show an excessive pro-inflammatory profile. Our objective is to assess the activation of T cells and innate immune cells (via an anti-CD3 agonist and a TLR7-8 ligand, respectively) from a blood sample to predict implantation success after frozen embryo transfer. This functional test is easy to use and applicable in a clinical routine.
Immature eggs obtained during the oocyte retrieval cycle are discarded as medical waste because they cannot complete fertilization, but each egg is important for people with poor clinical outcome. In vitro maturation (IVM) technique allows immature GV and MI eggs to mature in vitro, offering hope for this population to increase the clinical pregnancy rate in a single oocyte retrieval cycle. However, the clinical effectiveness of IVM clinical application is still very low, especially the utilization rate of GV eggs is extremely low. The cocktail of small molecules includes four chemical components of LCDM, which are related to cell proliferation, in vitro maturation of eggs, and protection of cells from oxidative stress. Our preliminary experiments confirmed that the addition of a certain concentration of LCDM in the culture medium can significantly improve the in vitro maturation rate and embryo utilization rate of immature GV eggs. In this study, LCDM immature oocyte culture system was used to carry out in vitro maturation culture of GV oocytes, and combined with oocyte activation technology to verify the clinical safety of LCDM in vitro culture system by observing the in vitro maturation rate, fertilization rate and embryo development results of GV oocytes, so as to provide laboratory data for clinical application of GV oocytes in special patients.
Observational, descriptive, cross-sectional, monocentric study, This Study is proposed to all couples followed in Assisted Reproduction and CECOS Nord for whom the protocols were stopped when they entered into confinement related to the Covid-19 epidemic on 13 March 2020.
We wish to evaluate sexuality during pregnancy between spontaneous pregnancies and resulting from assisted procreation The literature is poor on thie subject
All participants started with a combination of recombinant FSH 300 U and urinary Gn 150 U from the 2nd day of the cycle then the dose was adjusted according to the ovarian response From day 6 of the cycle, follow up using transvaginal ultrasound was done either daily or on alternate days according to the ovarian response. When the leading follicle reached 12 mm, GnRH antagonist was started using Cetrotide 0.25 subcutaneously daily till the day of triggering. Triggering was done when at least 3 follicles larger than 14 mm and at least one of them reached a mean diameter of 17 mm or more. At the day of triggering, women were randomized into 2 groups. Group I (single trigger group) that included 80 women who received triggering in the form of 10,000 IU of HCG intramuscular injection. Group II (Dual trigger group) that included 80 women who received triggering in the form of 10,000 IU of HCG intramuscular injection in addition to GnRH agonist triptorelin 0.2 mg subcutaneously. Ovum pickup was done 34 hours after triggering under the guidance of transvaginal ultrasound. ISM1 culture medium was used for oocyte collection and embryo culture. Transabdominal ultrasound guided embryo transfer was done 3 days after oocyte retrieval using Labotect semirigid catheter by the same expert operator Cycle cancellation was done if day 9 folliculometry revealed less than 2 mature follicles, no oocytes were retrieved or if fertilization failed Luteal phase support was started in all women on the day of oocyte retrieval and continued till the day of serum β-hCG assessment (done 14 days after ET) through administration of 400 mg of natural Progesterone twice daily per vagina . In women with +ve serum β-hCG (> 5 mIU/ml), transvaginal ultrasound evaluation was done 4 weeks after ET to confirm the presence and number of intrauterine gestational sacs.
This study evaluates the clinical efficacy of 3 different luteal phase support in patients undergoing frozen-thawed embryo transfer cycles. Endometrium preparation will be hormone replacement in all cycles. Starting from day 11, group 1 will receive 100 mg micronized progesterone parenteral daily injections, group 2 will receive 90 mg bioadhesive gel vaginal twice daily and group 3 will receive 40 mg oral dydrogesterone daily tablets.
A cohort study involving 200 women candidate for IVF / ICSI cycles . The participants will be assessed through full history-taking with special consideration to age and the duration, type, and cause of infertility. The medical examination included general, abdominal, and vaginal examinations. Finally, an ultrasonography examination was performed to check for the presence of three or more preantral follicles and to exclude ovarian cysts. On day 3 of a natural cycle, a baseline levels of FSH, luteinizing hormone (LH), , estradiol and anti-Müllerian hormone (AMH).Ovarian stimulation was performed using a long, antagonist, or short protocol. They were assigned to one of the 2 groups according to having an intramural myoma not indenting the cavity or not. All will be followed up by transvaginal ultrasonography . When two or more follicles had reached a mean diameter of 18 mm, oocyte maturation was triggered by intramuscular administration of hCG. Embryo transfer will be done at day 2, 3 or 5 according to the circumstances.
Ninety women with PCOS candidate for ICSI were randomized to 2 groups:Group A: fresh samples of PCOS patients undergoing IVF (no= 45) and Group B: frozen samples of PCOS patients undergoing IVF (no= 45). Morphologically good embryos will be cultured in a culture dish and the supernatants will be collected freshly from culture system at day 3 and stored at -20 ̊ c until being tested. Morphologically good embryos scheduled for freezing will be cryopreserved for less than one year and thawed, the supernatant will be collected and stored at -20 ̊ c until being tested. Quantification of mtDNA in fresh and frozen culture media using qPCR technique.The template DNA prepared and the dilution standards prepared will be used for qPCR to determine the amount of MtDNA and nuclear DNA in the sample using QuantiTect SYBR Green PCR Kit
Efficacy of the use of GnRH antagonist in treatment of those who develop early-onset severe ovarian hyperstimulation syndrome and had cancelled embryo transfer
Records of women who had trophectoderm biopsy for sex selection over the last 3 years will be reviewed and its outcome will be compared to other records of women who had IVF/ICSI without embryo biopsy.
