All the treatment or procedure that includes the handling of both human sperm and oocytes or embryos in vitro for the purpose of establishing a pregnancy in order to bypass some pathological obstacles in human reproduction is known as Assisted Reproductive Technology (ART). Now we must be approaching 1.5 million Assisted Reproductive Technology birth since the birth of the world’s first in vitro fertilization baby, Louise Brown, in the United Kingdom. The infertility is caused by various reason and factors from either or both partners. Infertility affects worldwide by 8-15 percent of couples in general and defined as a disease of the reproductive system by the failure to achieve a clinical pregnancy after one year or more of regular unprotected sexual intercourse.

The review presents data on metabolites in the follicular fluid (FF) from the perspective of reproductive medicine and their use in order to predict outcomes of assisted reproductive technology (ART) programs. It considers various components of this biological medium (hormones, lipids, melatonin, etc.) with an assessment of their predictive value in prognosis of the effectiveness of in vitro fertilization (IVF) programs. The data on experimental directions in this field and the prospects for their use in clinical practice are presented. The article emphasizes that the growing clinical need and the unsolved problem of increasing the effectiveness of ART programs determine the need for further studies of the FF composition. Materials and methods. The review includes data related to this topic from foreign and Russian articles found in PubMed which were published in recent years. Results. Given the established fact of a direct effect of FF composition on growth and maturation of oocytes, and further, on the fertilization process, various FF metabolites are actively investigated as non-invasive markers of quality of oocytes/embryos. The article provides data on the experimental directions in this field and the prospects for their use in clinical practice. However, clinical studies of a relation between various FF metabolites levels and outcomes of IVF programs are contradictory. Conclusion. Owing large economic cost for treatment of infertility with IVF, there is need for expansion and intensification of studies to identify and use reliable predictors in prognosis of ART programs outcomes.

Objectives:To evaluate the outcomes of pregnancy in young women (<40 years old) with early endometrial cancer or atypical complex hyperplasia who were treated by conservative management followed by assisted reproductive technology (ART).Materials and Methods:Medical charts of 11 patients treated from January 1997 to October 2007 at Asan Medical Center were retrospectively reviewed. These patients had all been treated with progestin and serial dilatation and curettage as primary fertility-preserving therapies.Results:After pathological remission of disease, 10 patients tried to become pregnant by ART, 4 by in vitro fertilization and embryo transfer, and 6 by controlled ovarian hyperstimulation, with or without intrauterine insemination. Eight women had intrauterine pregnancies, and 6 patients had live births. Patients have been followed up for 9 to 51 months (mean, 21 months) after delivery, with no evidence of tumor recurrence.Conclusions:Fertility-preserving therapy followed by ART can be a good option in well-selected patients with early endometrial cancer who want to become pregnant.

The aim of this paper was to provide reliable evidence by performing a systematic review and meta-analysis for evaluating the role of acupuncture in assisted reproductive technology. All randomized controlled trials that evaluated the effects of acupuncture, including manual, electrical, and laser acupuncture (LA) techniques, on the clinical pregnancy rate (CPR) and live birth rate (LBR) of in vitro fertilization (IVF) or artificial insemination were included. The controlled groups consisted of no acupuncture and sham acupuncture groups. The sham acupuncture included sham acupuncture at acupoints, sham acupuncture at non- or inappropriate points, sham LA, and adhesive tapes. Twenty-three trials (a total of 5598 participants) were included in this paper. The pooled CPR from all acupuncture groups was significantly higher than that from all controlled groups, whereas the LBR was not significantly different between the two groups. However, the results were quite distinct when the type of control and/or different acupuncture times were examined in a sensitivity analysis. The results mainly indicate that acupuncture, especially around the time of the controlled ovarian hyperstimulation, improves pregnancy outcomes in women undergoing IVF. More positive effects from acupuncture in IVF can be expected if a more individualized acupuncture programs are used.

Purpose.To improve success of in vitro fertilization (IVF), assisted reproductive technology (ART) experts addressed four questions. What is optimum oocytes number leading to highest live birth rate (LBR)? Are cohort size and embryo quality correlated? Does gonadotropin type affect oocyte yield? Should “freeze-all” policy be adopted in cycles with progesterone >1.5 ng/mL on day of human chorionic gonadotropin (hCG) administration?Methods.Electronic database search included ten studies on which panel gave opinions for improving current practice in controlled ovarian stimulation for ART.Results.Strong association existed between retrieved oocytes number (RON) and LBRs. RON impacted likelihood of ovarian hyperstimulation syndrome (OHSS). Embryo euploidy decreased with age, not with cohort size. Progesterone > 1.5 ng/dL did not impair cycle outcomes in patients with high cohorts and showed disparate results on day of hCG administration.Conclusions.Ovarian stimulation should be designed to retrieve 10–15 oocytes/treatment. Accurate dosage, gonadotropin type, should be selected as per prediction markers of ovarian response. Gonadotropin-releasing hormone (GnRH) antagonist based protocols are advised to avoid OHSS. Cumulative pregnancy rate was most relevant pregnancy endpoint in ART. Cycles with serum progesterone ≥1.5 ng/dL on day of hCG administration should not adopt “freeze-all” policy. Further research is needed due to lack of data availability on progesterone threshold or index.
