Filter by: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.
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.
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
300 women with unexplained infertility who are already decided to be treated with ICSI will be recruited from Cairo university hospitals and Dar Al-Teb subfertility centre. On the second day of menstruation serum FSH, LH, Prolactin and Oestradiol will be assessed and the antral follicular count (AFC) will be assessed using a vaginal ultrasound scan. AFC will be defined as the number of follicles measuring 3-10mm. All patients will have standard pituitary down-regulation followed by (Human menopausal gonadotrophin (HMG) stimulation until the day of (Human chorionic gonadotrophin (HCG) administration. On the day of HCG administration, ovarian ultrasound scan will be performed using a transvaginal probe and the Preovulatory follicle count (PC) will be assessed, (PFC) is defined as number of follicles measuring≥16mm. FORT will be calculated as: (PFC) * 100/AFC.
