Abstract Background Although oocyte quality is the dominant factor determining embryo quality, few studies have been conducted to evaluate embryo quality based on the metabolites related to the oocyte. With quantification of the follicular fluid (FF) metabolites, in assisted reproductive technology (ART), this study sought to evaluate the embryo or oocyte quality through an informative approach. Results An evaluation model consisting of 17 features was generated to distinguish the embryo quality on day 3 post-fertilization, and phosphatidylcholines (PCs) were the key contributors to the evaluation. The model was extended to the patients under different ages and hyperstimulations, and the features were further enriched to facilitate the evaluation of the embryo quality. The metabolites were clustered through pathway analysis, leading to a hypothesis that accumulation of arachidonic acid induced by PCs might weaken embryo quality on day 3 post-fertilization. Conclusions A discriminating model with metabolic features elicited from follicular fluid was established, which enabled the evaluation of the embryo or oocyte quality even under certain clinical conditions, and the increase of PCs in follicular fluid implies the attenuation of embryo quality on day 3 post-fertilization.

Abstract Background Infertility is the third most serious disease worldwide estimated by the WHO. Despite the worldwide use of ICSI, it still has a low birth rate (30%). Patients and Methods The current study was a prospective study that included 180 women undergoing Intra-cytoplasmic sperm injection (ICSI) procedure. Using Flexible Antagonist protocol; during oocyte retrieval, follicular fluids of mature follicles (>17 mm) aspirated. Results The number of retrieved oocytes ranged from (1 to 33 oocytes) mean number 10±7. Follicular fluid E2 concentration ranged from 246±199 (0 to 700) (ng/ml). Oocyte maturation about 116 were MII (64.4%) of oocytes. And 64 (35.6%) were MI and GV. 107 cases (59.4) had normal fertilization [email protected] and 73(40%) had abnormal fertilization of MII injected oocytes. Embryo quality 63.9% (115) of fertilized MII oocytes were blastocysts and 65 (blastomere and others) and 60.6% of cases had embryo transfer on day 5 and 39.4 had transfer on day 3. Chemical pregnancy was positive in 85 cases (47.2%) and the clinical pregnancy positive in 66 cases (%). Conclusion Follicular fluid E2 concentration had fair predictive value in oocyte maturation, fertilization, embryo quality, chemical and clinical pregnancy. But it was an independent predictor of MII-grade oocytes production.

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.

Aim. To study the proteomic profile of follicular fluid in patients with infertility in assisted reproductive technology programs. Methods. The study included women with infertility included in assisted reproductive technology programs: 15 women who had in vitro fertilisation which resulted in pregnancy (group 1) and 16 women with a negative result of this program (group 2). Fractionation of the follicular fluid samples was performed using the sets of special magnetic beads. Proteomic profiling was performed by tandem MALDI-mass-spectrometry. The anti-Müllerian hormone level was measured by ELISA. Results. The study revealed differences in the detectability of follicular fluid proteins with different regulatory properties in patients of groups 1 and 2. With the negative outcome of in vitro fertilisation, expression of a number of proteins involved in the processes of folliculogenesis, ovulation, selection of the dominant follicle, as well as proteins necessary for the development of the zygote and blastula was reduced in females' follicular fluid. Increased expression in women from group 2 was registered for proteins enhancing proteolytic reactions, cell apoptosis, including oocytes, which disrupt the positive action of activin and damage structural and functional state of mitochondria. A definite relationship was found between the level of anti-Müllerian hormone and rate of detection of a number of proteins, in particular protocadherin-2α, cystatin C, betaglycan, prostatic acid phosphatase, and dermicidin. Conclusion. The revealed changes in proteomic profile of the follicular fluid obviously play an important role in the molecular mechanisms that determine the effectiveness of assisted reproductive technologies; the identified differentially expressed proteins can serve as objective markers for predicting the outcomes of in vitro fertilisation.

Abstract The aim of this study was to evaluate if cytoplasmic transfer can improve fertilization and embryo quality of women with oocytes of low quality. During ICSI, 10–15% of the cytoplasm from a fresh or frozen young donor oocyte was added to the recipient oocyte. According to the embryo quality, we defined group A as patients in which the best embryo was evident after cytoplasmic transfer and group B as patients in which the best embryo was evident after a simple ICSI. We investigated in the period of 2002–2018, 125 in vitro fertilization cycles involving 1011 fertilized oocytes. Five hundred fifty-seven sibling oocytes were fertilized using ICSI only and 454 oocytes with cytoplasmic transfer. Fertilization rates of oocytes were 67.2% in the cytoplasmic transfer and 53.5% in the ICSI groups (P < 0.001). A reduction in fertilization rate was observed with increased women age in the ICSI but not in the cytoplasmic transfer groups. The best embryo quality was found after cytoplasmic transfer in 78 cycles (62.4%) and without cytoplasmic transfer in 40 cycles (32%, P < 0.001). No significant differences were detected between the age, hormonal levels, dose of stimulation drugs, number of transferred embryos, pregnancy rate and abortion rate between A and B groups. Cytoplasmic transfer improves fertilization rates and early embryo development in humans with low oocyte quality. All 28 children resulting from cytoplasmic transfer are healthy.

We studied the concentration of serum estradiol and serum and follicular fluid leptin in 200 women undergoing their first in vitro fertilization with embryo transfer (IVF-ET) program at the time of human chorionic gonadotrophin administration and oocyte retrieval, in an attempt to assess their concerted role on embryo quality and the prognosis of IVF outcome. Low serum (46.49 ± 8.4 ng/ml) and follicular fluid (52 ± 9.8 ng/ml) leptin levels were associated with a high number of ‘good-quality’ embryos (73.6%) and high implantation (11.2%) and pregnancy (35.8%) rates and were observed in women with normal peak estradiol levels of between 1000 and 2000 pg/ml. It appears that leptin and estradiol interact coordinately in a concentration-dependent manner to control IVF outcome. Further studies will be required to substantiate and clarify the mechanism of proposed conditional interaction between the two hormonal systems.
