Filter by:Retrieval of an oocyte from a follicle relies on the release of the cumulus-oocyte-complex (COC) from the follicular wall into the lumen, thereby allowing aspiration by a needle. Flushing the follicle with multiple aspirations from the same follicle is used as a means to increase the ratio of COC per aspirated follicle. Data showed that follicular flushing is not superior to direct aspiration either in normally responding patients or in poor responders undergoing in vitro fertilization (IVF). There is no data in the literature regarding the issue in patients with mono-follicular growth. Direct aspiration or repeatedly flushing the follicle for those with a single follicle will be investigated.
After detailed history and examination, long luteal protocol will be used for controlled ovarian hyperstimulation, so the patient will start treatment in day 21 of previous cycle, then in the early follicular phase of next cycle day 2-3 will have transvaginal sonography for assessment of total ovarian volume and number of antral follicles measuring (2-10mm) in diameter. On the same day a venous sample will be obtained for the measurement of AMH, basal FSH and E2 levels
This prospective study will be conducted on 120 patients candidates for ICSI cycle and following the long protocol for controlled ovarian stimulation; the patients were randomly allocated in a 1:1 ratio to either group A; where the embryo transfer was assisted by transabdominal ultrasound and group B; where the embryo transfer was assisted by Transvaginal ultrasound. The study nurse opened the sealed envelopes according to sequence of attendance of patients to allocate patients to the assigned group. Both the patient and the operator were blind to the assigned group. All the transfers were done on day 3 after OPU for at least 2 grade I embryos using the Edwards-Wallace embryo replacement catheter using the same ultrasound device. Quantitative serum hCG test was done for all patients 14 days after the transfer.
Induction of ovulation cycle: 1. Gonadotrophines is started on day 2 with HMG(merional, IBSA) ,until the day of HCG administration(choriomon,IBSA10000IU) with starting dose 300 to 450iu. 2. GNRH antagonist (cetrorelix 0,25mg s.c, cetrotide, serono laboratories, Aubonne Switzerland) is given using flexible protocol, it is given when at least one follicle reaches size 14 mm to prevent premature lutenization ,until the day of hCG administration 3. Ovarian ultrasound scans were performed using a 5.0-9.0 MHZ multi frequency trans vaginal probe (mindrayDP-5)to assess the ovarian response till the mature follicles reach18-20mm when hCG administration 10000 IU is given.Serum E2 level is done on day of HCG trigger. 4. Trans vaginal ultrasound-guided oocyte retrieval is performed 34-36 hours after hCG injection 5. Progesterone vaginal tablets (Prontogest,IBSA) are administrated 400mg twice daily as luteal support from the day of oocytes retrieval. 6. Ultrasound -guided fresh embryo transfer is performed on day 2 or 3 after fertilization. 7. Serum hCG assessment to detect pregnancy is performed at 14 days after embryo transfer .if positive(chemical pregnancy) ,women undergo trans -vaginal ultrasonography 2 weeks after, to confirm fetal pulsations as well as number of gestational sacs (clinical pregnancy). 8. The implantation rate is calculated as the number of viable embryos divided by the number of transferred embryos multiplied by 100
infertile , poor responders patients who underwent ICSI. The participants were divided into 2 groups according to the starting dose of Gn stimulation. Group I started with 4 ampoules while group II started with 6 ampoules
Ovarian stimulation will be done using the Microdose flare-up regimen. The patient will receive diluted doses of the GnRH agonist leuprolide acetate 40 µg, given subcutaneously twice daily. Two days later, stimulation will be initiated by intramuscular (IM) injections of HMG (Merional, IBSA, Germany) in a dose of 300 IU/day. Follicular monitoring began from the ninth day of the cycle by serial vaginal ultrasonography and measurement of serum E2 levels. IM injections of 10000 IU HCG (Choriomon; IBSA, Germany) will be injected when at least 2 follicles 18 mm were observed on ultrasonography. Oocytes willbe retrieved 36 hours after hCG injection using a 17-gauge aspiration needle under transvaginal ultrasound guidance. The pelvis is evaluated with ultrasound to ensure that there is no internal bleeding. After fertilization was confirmed when two polar bodies and two pronuclear were observed 18-20 hours after insemination, one to three grade A embryos were transferred at day 3 fertilization. The luteal phase support will be initiated from the day of oocyte retrieval for all patients with (Cyclogest 400 mg, Actavis pharmaceutical, UK) vaginal suppositories per day till the day of serum pregnancy test was done.
Patients will be divided into two groups Group A; patients using long protocol and freeze all embryos Group B; patients using antagonist protocol with fresh embryo transfer Patients will be carefully chosen according to a strict inclusion and exclusion criteria after meticulous revision of patient files. In the long protocol, daily SC injection of Triptorelin :Decapeptyl 0.1 mg (Ferring, Switzerland) 0.1 mg started at day 21 of the cycle prior to stimulation cycle and continued till the day of hCG triggering. Gn stimulation started after fulfilling stimulation start criteria of thin endometrium < 5 mm and low E2 < 50 and LH < 5IU/l with either HMG(Menogon; Ferring, Switzerland) or rFSH (Gonal-f; Merck Serono, Germany) in a starting dose of 150-300 IU/day according to women age, day 3 FSH,AMH and previous gonadotropin response then adjustment of the dose according to ovarian response monitored by serum E2 and ultrasound evaluation. All patients were followed up by Transvaginal ultrasound scan daily or on alternate days according to the ovarian response to treatment starting on treatment cycle day (6) for folliculometry and endometrial thickness and pattern. Triggering by HCG 10000 IU IM (Pregnyl, Organon, the Netherlands) when 2 or more follicles have 18 mm as a mean diameter . Flexible GnRH antagonist protocol was done with daily s.c administration of cetrorelix 0.25 mg (Cetrotide, Merck Serono, Darmstadt, Germany) started when one or more of the following criteria were achieved: (i) one or more follicle reached 14 mm diameter; (ii) The level of serum E2 reached 600 pg/ml; and (iii) The level of serum LH levels reached 10 IU/l . Daily sc rFSH (Gonal-f; Merck Serono , Darmstadt, Germany) injections was started on 2nd day of the cycle in the antagonist protocol. Continuation of rFSH and GnRH antagonist daily until triggering day was done.
cases with embyos cultured in the standard incubator and evaluated only by morphology are compared to cases with embryos continuously monitored by the embryoscope followed by embryo selection based on a multivariable model
All women had normal uterine cavity determined by previous hysterosalpingography or hysteroscopy. Women with abnormally low Gn as hypothalamic hypogonadism , High LH as PCOS and women with abnormal endocrine functions as abnormal thyroid or adrenal functions were excluded. Any woman with ovarian cyst or azopermic male partner was also excluded. The patients were subjected to history taking, including age, duration, type and cause of infertility and medical history. Full examination including general and abdominal and vaginal examination was done followed by ultrasound evaluation for presence of 3 or more pre-antral follicles and exclusion of ovarian cysts. Basal day 3 hormonal evaluation for FSH, LH and E2 in a natural cycle was done. E2, FSH and LH levels were determined using Immulite system (Siemens Healthcare diagnostics,UK).The intra- and inter-assay coefficients of variation were 15% and 16% for E2, 4.8% and 26% for LH. FSH analytical sensitivity was 0.1 mIU/ml. All participants underwent long protocol. Daily SC injection of Triptorelin : Decapeptyl 0.1 mg (Ferring, Switzerland) 0.1 mg started at day 21 of the cycle prior to stimulation cycle and continued till the day of hCG injection. Gn stimulation started after fulfilling stimulation start criteria of thin endometrium < 5 mm and low E2 < 50 and LH < 5IU/l [18] with either HMG(Menogon; Ferring, Switzerland) or rFSH (Gonal-f; Merck Serono, Germany) in a starting dose of 150-300 IU/day depending on patients age and previous gonadotropin response. then the dose was adjusted according to ovarian response monitored by serum E2 and ultrasound evaluation. All patients were followed up by Transvaginal ultrasound scan daily or on alternate days according to the ovarian response to treatment starting on treatment cycle day (6) for folliculometry and endometrial thickness and pattern. Triggering by HCG 10000 IU IM (Pregnyl, Organon, the Netherlands) when at least 2 follicles reached a mean diameter of 18 mm [18] Cycle cancellation was decided when transvaginal ultrasound scan on cycle day (9) revealed no adequate follicular growth (<3 mature follicles). Ovum pick-up (OPU) was done 34-36 hours after hCG injection under transvaginal ultrasound guide.
Midluteal single endometrial strip will be taken using a Novak curett under general anasthesia to avoid discomfort and cramping and to proceed to cervical dilatation in case of forbidden cervix, the step that will be beneficial to embryo transfer procedure. Controller ovarian hyperstimulation; will be done using the long luteal phase agonist protocol and the short protocol(as judged by patient,s age ovarian reserve judged by day 3 FSH and antral follicular count and previous history of ovarian response). Ovarian response will be monitored by vaginal ultrasound and HCG will be given when when there is >=1 follicle >=18 mm. and >=3 follicles >=16 mm. Ultasound guided oocyte retrieval will be carried out 35 hours later. Embryo transfer will be performed on day 2 or day 3 after oocyt retrieval according to number and quality of embryos. Embryo transfer will be carried out under trans-abdominal ultrasound guidance pregnancy test will be done using qualitative blood HCG detection 2 weeks after the embryo transfer.
