Three types of assisted reproductive technology treatment of infertile women with polycystic ovary syndrome compare the efficacy of

O. 05). 3 Discussion 3.1PCOS PcOs pathogenesis of endocrine abnormalities mainly for excessive secretion of LH and FSH relative, so that T ovaries produce too much, thus the role of gonadal aromatase other than providing more substrate,[link widoczny dla zalogowanych], resulting in peripheral tissue E too. E can increase the sensitivity of the pituitary of GnRHa, it secrete more LH. Abnormal LH / FSH ratio eventually lead to anovulation and infertility. 3.2Pc0S the treatment of patients although some patients with PCOS ovulation induction drugs can restore ovulation, but prone to OHSS and multiple pregnancy, in order to avoid 0Hss, on the basis of clinical manifestations and endocrine, ultrasonography has typical PCOS performers. We used in vitro assisted reproductive technology, the IVF-EF, or GIFT, because in the majority of vaginal ultrasound follicle aspiration under the guidance will be clean, directly reduce the E level, reduction of LH to avoid the risk of OHSS. Our data show that in vitro assisted reproductive technology has not taken the PCOS patients, the incidence of OHSS was significantly higher than that of IVF-ET group and the GIFT group. Therefore, for PC (kS patients, found during ovulation OHSS can occur when the in vitro assisted reproductive technology should be considered. 3.3 The revelation of this information 1, I set the basis of age and endocrine status in essentially the same obtained under a similar clinical pregnancy rate, I group is the application of a GnRHa and FSH-line treatment for ovulation induction. GnRHa Advances in Obstetrics and Gynecology Volume 8 1999 3 pituitary desensitization by inhibiting the emergence of endogenous LH peak so that the whole gonadal endocrine axis system synchronization, and improved egg quality and increase the receptivity of the endometrium improves the clinical pregnancy rate, Ⅱ group did not use the GnRHa, which gained considerable success rate of pregnancy, to improve cOH programs (such as the addition of RnRHa) can further improve the pregnancy rate after it, pending further research from other scholars also found that the clinical pregnancy rate of GIFT than IVF-ET. Therefore, PCOS patients which should be preferred in vitro assisted reproductive technology is the need to consider the issue from different perspectives. 3.4GIFT advantages and disadvantages of the advantages of GIFT future improvements of the natural environment is more suitable for tube fertilization, and zygote transport volume is also suitable for tubal implantation timing of naturally occurring, so that higher pregnancy success rate; disadvantage is that if did not get pregnant,[link widoczny dla zalogowanych], no way of knowing whether or not fertilization can not derive conclusions, lack of guidance on the future role of the treatment. Therefore, many scholars tend to apply in a cycle of IVF-ET treatment. confirmed in vitro fertilization and cleavage are normal, then consider the GIFT.. In addition, GIFT requires at least l in patients with completely normal fallopian tube section. Thus,[link widoczny dla zalogowanych], for different cases should be treated differently. In fact, if a patient suitable for GIFT treatment, because the characteristics of PCOS,[link widoczny dla zalogowanych], often from a number of eggs after cOH; can be 3 to 4 eggs for intrafallopian transfer, and then the remaining egg in vitro fertilization, fertilization and cleavage can still be observed the situation, there is still the treatment of the future guidance; can be cryopreserved embryos obtained to the transplant in the next cycle.
