Embryo survival rate, implantation rates and clinical pregnancy rates per transfer from fresh and cryopreserved cycles were analyzed. Results From January to December, 2002, in a total of 628 thawing cycles in which 1 876 embryos were thawed, the embryo survival rate was similar between the IVF and ICSI group (88.09% and 88.95%, respectively). There was no significant difference in implantation rates both between the frozen and fresh IVF groups (19.19% and 21.07%, respectively) and between the frozen and fresh ICSI groups (15.22% and 15.64%, respectively), but there were significant differences either between frozen IVF and frozen ICSI groups (P<0.05) or between fresh IVF and fresh ICSI groups (P<0.01). The clinical preg- nancy rates in the frozen and fresh IVF groups were 45.86% and 43.43%, respec- tively (P>0.05). The clinical pregnancy rate of the frozen ICSI group was 42.07%, slightly higher than that of fresh ICSI (35.43%), but the difference was not significant (P>0.05). The clinical pregnancy rate between fresh IVF and fresh ICSI was signifi- cantly different (P<0.05). Conclusion The present study indicated that frozen-thawed embryos at early cleavage stage had equivalent pregnancy rates as that of fresh embryos.展开更多

ICSI is done for reasons other than male factor infertility, and on the whole has not been shown to have any more negative effects than those seen with IVF. There have however, been very few studies of ICSI with a focus on, or large enough numbers to examine, the specific outcomes associated with male factor infertility. From the limited information available in relation to the source of the sperm and aetiology of infertility in the presence of ICSI, there appears to be no increased risk of congenital malformations. There is, however, a small increase in both de novoand inherited chromosome abnormalities. In terms of growth and neurodevelopment, there are very few studies, and so far, no adverse outcomes have been found in young children whose fathers have a sperm defect. The origin of the sperm used in ICSI does not have a major influence on the early life outcomes for the offspring, but transgenerational and epigenetic effects remain unknown. When the male factor infertility is known or thought to be due to a Y-chromosome deletion, this information should be given to the young male offspring at a time that will ensure his own reproductive health and plans are optimized.展开更多

Our objective was to study the association between PCOS phenotypes and IVF/ICSI results in women admitted to Gynaecological Endoscopic Surgery and Human Reproductive Teaching Hospital (CHRACERH). Material and Method: We carried out a cohort study with historical-prospective data collection over a period of seven years (January 2016 to March 2023) at Chracerh. PCOS patients were subdivided into 4 subgroups A, B, C and D. Results: We recruited 128 patients including 64 PCOS patients divided into four phenotypes and 64 non-PCOS patients constituting the control group. Phenotype D without hyperandrogenism had used the lowest dose of gonadotropins, i.e. 1939.7 ± 454.3 IU, and had produced a greater quantity of estradiol on the day ovulation was triggered (6529.8 ± 4324.8 ng/ml). The average number of punctured follicles and mature oocytes were higher in the phenotype D group. Ovarian hyperstimulation syndrome (OHSS) occurred mainly in phenotype D (3/35), with an estimated prevalence of 2.3%. The fertilization rate seemed lower in the hyperandrogenic phenotypes A, B, C compared to the group without hyperandrogenism without significant difference (p = 0.461). The biological pregnancy rate and live birth rate were comparable between the different groups. Conclusion: Phenotype D used less dose of gonadotropins. Biological pregnancy and live birth rates were comparable between the different phenotypes.展开更多
