They were all under 37 years old, had more than 8 mm of endometrial thickness on the day of human chorionic gonadotropin hCG administration, and had more than three good quality embryos esbet Sakibet Normal day 3. All patients gave written informed consent for eSMET or eSBET. This study did not include oocyte donation cycles.
Ovarian stimulation was undertaken using the gonadotropin-releasing hormone GnRH agonist long protocol and recombinant follicle stimulating hormone FSH; Gonal-F, Merck Serono, Germany. Oocyte maturation was induced by 10, IU of hCG IVF-C, LG Life Science, Daejon, Https://mister-baches.com/3-slot-machine/mroyun-para-yatrma-ve-ekme-hzlar-52.php when more than two follicles 17—18 mm in diameter were visible on ultrasonography.
Oocyte retrieval was undertaken by transvaginal ultrasound-guided aspiration after 36 hours of hCG administration. The retrieved oocytes were washed in MRC OW medium Biosupply Co. until in vitro fertilization. In vitro fertilization was induced using conventional insemination or intracytoplasmic katarbet Canlı Eğlencesi injection ICSI.
IntroductionWithin 16 to 18 hours after fertilization, the oocyte with two pronuclei and a second polar body was regarded to be normally fertilized. The embryos were co-cultured with autologous cumulus cells ACC in 20 μl of MRC D16 medium YS medium [ 20 ], Esbet Sakibet Normal Co.
containing autologous follicular fluid AFF. Grandroyalbet Neden Bu Kadar Popüler was collected from follicles that produced healthy mature oocytes with a clear corona radiata. AFF was used for culture after inactivation at 56°C for 30 minutes and sterilization with a 0. ACCs were prepared in a 5 μl micro droplet of an organ culture dishBD Falcon, USA under MRC Oil Biosupply Co.
by seeding its single cells, followed by excising from a clear corona radiata of healthy cumuli and digesting with MRC Hyase Biosupply Co. Culture medium was exchanged for pre-equilibrated fresh medium every morning. The luteal phase was supported by administration of Crinone gel 90 mg, Merck Serono, Germany and Utrogestan mg, France for 14 days after oocyte retrieval.
The Crinon gel was taken once a day vaginally, while the Utrogestan was taken orally three times a day. The quality of cleavage embryos was assessed on the morning of day 3.
The quality of morula on day 4 was assessed according to the criteria of Tao et al. The eSMET on day 4 or eSBET on day 5 was completed by transferring a single best embryo into the uterine cavity in each group.
Access optionsAfter eSMET or eSBET, the surplus embryos were cocultured to day 5 or 6. Only the normal embryos that reached the blastocyst stage were selected for cryopreservation based on the healthiness of trophectoderm cells and the size of the inner cell mass. Serum β-hCG concentration was measured 14 days after oocyte retrieval to verify pregnancy.
Clinical pregnancy was judged by observation of the gestational sac G-sac on vaginal ultrasonography after weeks of esbet Sakibet Normal. The implantation rate was indicated as the proportion of the gestational sacs to the transferred embryos.
Monozygotic twins were considered as two gestation sac. Ectopic pregnancy was not counted as implantation and clinical pregnancy.
Statistical analysis was performed with SPSS Among cycles, eSMET was performed for cycles on day 4, and eSBET was conducted for cycles on day 5.
The demographic characteristics between the eSMET group and the eSBET group are summarized in Table 1. There were no differences between the eSMET and eSBET groups in terms of the age of women, number of previous IVF cycles, endometrial thickness at hCG administration, or are betsobet Mevcut Adresiniz Nedir agree of infertility.
However, the tubal factor rate of the eSMET group was higher than that of the eSBET group, while other factors, including unknown, were lower in the eSMET group compared to the eSBET group in terms of the etiology of infertility. These values were not statistically significant. The proportion of cycles undergoing ICSI was similar in the two groups With respect to the laboratory outcomes, there were no differences in the numbers of retrieved, matured, fertilized oocytes and good quality embryos on day 3.
However, the number of cryopreserved blastocysts 5. The ectopic pregnancy rate 3. Only one case of a pregnancy with monozygotic twins was found in each group 1. The eSMET group showed a trend with a lower live orisbet Para Yatırma rate The rate of low birth weight infants less esbet Sakibet Normal 2, g in the eSMET group was statistically identical to that of the eSBET group.
However, the rate of preterm births before 37 weeks was slightly higher in the eSBET group 6. There was 1 case of monozygotic twin births in both groups, and they were delivered by Caesarean section at 39 weeks in the eSMET group weights 2.
In most human IVF-ET programs, embryos are typically transferred 2 or 3 days after oocyte retrieval or 2 to 3 days later, when they have esbet Sakibet Normal the blastocyst stage. Similarly, most eSET have been mainly performed on day 2, 3, or 5. These studies have shown that the clinical pregnancy and delivery rates were significantly higher after eSBET compared to eSCET in selected patients [ 11 — 13 ].
The present retrospective study comparing eSMET to eSBET showed that the clinical pregnancy and live birth rates after eSMET were similar to those after eSBET in women with favorable conditions. It is standard that ET on day 4 or day 5 is performed for patients with more than 3 good quality embryos on day 3.
However, most of the patients with embryos produced by ICSI are excluded from this standard, although they have more than 3 good quality embryos, except that they want to be transferred on day 4 or day 5. The reason is because the blastocyst formation rate is lower in the embryos fertilized by ICSI than those fertilized by conventional insemination [ 22 ]. Thus, it was found that the attempt ratio of ICSI was very low in both groups Table 2. In order to maintain a satisfactory pregnancy and reduce multiple pregnancies, the most successful way is transfer of a single embryo with the highest potential for implantation.
However, it would be difficult to accurately select cleavage-stage embryos with the highest implantation potential for ET [ 23 ]. On the other hand, some researchers have suggested that blastocyst results in improved selection of developmentally competent embryos compared to cleavage stage embryo, because embryonic genome activation occurs, and embryos with genetic abnormalities have difficulty developing to the blastocyst stage during extended culture [ 1824 ].
In terms of embryo selection, Tao et al. Also, Harper reported that the embryo travels to the uterine cavity about 3—4 days after fertilization in mammals [ 19 ]. This indicates that the morula-stage ET would be more synchronized with in vivo reproductive processes than cleavage-stage ET on day 3.
According to the results of our study, it is considered that the transferring of morula-stage embryo on day 4 may have potential advantages similar to blastocyst transfer associated with embryo selection and synchronization between embryo and the uterine environment. Further study is needed to determine whether or not day 4 transfer is efficient. Gardner et al. However, it has been associated with an increased risk of cancelled transfer as compared to day 3 ET due to failed blastocyst development.
Thus, it has mainly been applied to patients esbet Sakibet Normal at least two [ 26 ] ~ five [ 27 ] top quality embryos on day 3. Our study also included patients with more than three good quality embryos on day 3.
Thus, there were no cases of cancelled ET. We did not investigate morula and blastocyst formation rates. However, according to previous studies, These results suggest that the rate of ET cancellation is lower after morula-stage ET than blastocyst-stage ET.
A study on morula-stage ET cancellation has not been conducted, and a prospective, randomized study should be performed to investigate this issue. In the present study, the pregnancy rate was similar in both groups, whereas the delivery rate was slightly lower in the eSMET group This difference is related to a higher rate of pregnancy loss in the eSMET group, although the difference was not significant It has been known that pregnancy loss before weeks of pregnancy is related to poor embryo quality [ 30 ].
De Neubourg et al. However, the patients included in our study were women under 37 years of age who had more than three good quality embryos on day 3. When one https://mister-baches.com/2-slot-game/nightwin-casino-poker-33.php is transferred, monozygotic twin pregnancies rarely occur, while dizygotic twin pregnancies could be completely prevented. It has been reported that pregnancies with monozygotic twins have resulted in higher perinatal morbidity and mortality compared to those with dizygotic twins [ 32 ].
Da Costa et al. Guerif et al. However, Papanikolaou et al. In the present bahislion Yeni Adresi, the proportion of monozygotic twin pregnancies after eSBET was 1.
This rate girne Yenilik in accordance with previous studies of monozygotic twin pregnancies rate after eSBET [ 34 ]. Also, the rate of monozygotic twin pregnancies after eSMET was 1.
Our results showed that the number of monozygotic twin pregnancies in both groups was not increased. Hum Reprod Update. McArthur SJ, Leigh D, Marshall JT, de Boer KA, Jansen RP.
