In recent years there has been an increase in the frequency of multiple pregnancies and the associated perinatal losses. It is a result of multiple pregnancy in ART refers to a high-risk gestation, at which premature births occur in 2 times more often than in singleton pregnancies. The objective: to determine the role of pro-inflammatory cytokines in the pathogenesis of premature labor in multiple pregnancy, as a result of assisted reproductive technology. Patients and methods. to determine the pro-inflammatory cytokines that all pregnant with bagtopliddyam held immunosorbent assay, defined concentrations of interleukin (IL) in serum and cervical mucus. Results. The analysis of the levels of pro-inflammatory cytokines (IL-1, IL-8) in the test environment, found high concentrations in the surveyed women with multiple pregnancy, due to the use of ART, compared with spontaneous multiple and singleton pregnancy. Increased concentration of proinflammatory cytokines in patients with multiple pregnancy by ART is associated with their synthesis at the system level, it stimulated foci of inflammation in the female genitals and extragenital localization. This correlates with the clinical data and statistical analysis, patients with multiple pregnancy as a result of ART had weighed infectious-inflammatory history. Conclusion. The study showed that elevated levels of proinflammatory cytokines in the systemic and local level in patients with multiple pregnancy due to ART, typical for women with miscarriage, because of the physiological course of pregnancy characterized by the predominance of anti-inflammatory cytokines that prevent rejection of the fetus as a foreign factor. Based on the data obtained proved the role of systemic inflammatory factors in the genesis of preterm labor in women with a multiple pregnancy, as a result of assisted reproductive technology. Key words: multiple pregnancy, assisted reproductive technology, premature birth, interleukine-1, interleukine-8.

Abstract Background This study compared the effectiveness of recombinant human follicle-stimulating hormone alfa (r-hFSH-alfa; GONAL-f®) with urinary highly purified human menopausal gonadotropin (hMG HP; Menogon HP®), during assisted reproductive technology (ART) treatments in Germany. Methods Data were collected from 71 German fertility centres between 01 January 2007 and 31 December 2012, for women undergoing a first stimulation cycle of ART treatment with r-hFSH-alfa or hMG HP. Primary outcomes were live birth, ongoing pregnancy and clinical pregnancy, based on cumulative data (fresh and frozen-thawed embryo transfers), analysed per patient (pP), per complete cycle (pCC) and per first complete cycle (pFC). Secondary outcomes were pregnancy loss (analysed per clinical pregnancy), cancelled cycles (analysed pCC), total drug usage per oocyte retrieved and time-to-live birth (TTLB; per calendar week and per cycle). Results Twenty-eight thousand six hundred forty-one women initiated a first treatment cycle (r-hFSH-alfa: 17,725 [61.9%]; hMG HP: 10,916 [38.1%]). After adjustment for confounding variables, treatment with r-hFSH-alfa versus hMG HP was associated with a significantly higher probability of live birth (hazard ratio [HR]-pP [95% confidence interval (CI)]: 1.10 [1.04, 1.16]; HR-pCC [95% CI]: 1.13 [1.08, 1.19]; relative risk [RR]-pFC [95% CI]: 1.09 [1.05, 1.15], ongoing pregnancy (HR-pP [95% CI]: 1.10 [1.04, 1.16]; HR-pCC [95% CI]: 1.13 [1.08, 1.19]; RR-pFC [95% CI]: 1.10 [1.05, 1.15]) and clinical pregnancy (HR-pP [95% CI]: 1.10 [1.05, 1.14]; HR-pCC [95% CI]: 1.14 [1.10, 1.19]; RR-pFC [95% CI]: 1.10 [1.06, 1.14]). Women treated with r-hFSH-alfa versus hMG HP had no statistically significant difference in pregnancy loss (HR [95% CI]: 1.07 [0.98, 1.17], were less likely to have a cycle cancellation (HR [95% CI]: 0.91 [0.84, 0.99]) and had no statistically significant difference in TTLB when measured in weeks (HR [95% CI]: 1.02 [0.97, 1.07]; p = 0.548); however, r-hFSH-alfa was associated with a significantly shorter TTLB when measured in cycles versus hMG HP (HR [95% CI]: 1.07 [1.02, 1.13]; p = 0.003). There was an average of 47% less drug used per oocyte retrieved with r-hFSH-alfa versus hMG HP. Conclusions This large (> 28,000 women), real-world study demonstrated significantly higher rates of cumulative live birth, cumulative ongoing pregnancy and cumulative clinical pregnancy with r-hFSH-alfa versus hMG HP.

And Function

Peroxisome proliferator-activated receptorδ(PPARδ, also known as PPARβ) has ubiquitous distribution and extensive biological functions. The reproductive function of PPARδwas first revealed in the uterus at the implantation site. Since then, PPARδand its ligand have been discovered in all reproductive tissues, including the gametes and the preimplantation embryos. PPARδin preimplantation embryos is normally activated by oviduct-derived PPARδligand. PPARδactivation is associated with an increase in embryonic cell proliferation and a decrease in programmed cell death (apoptosis). On the other hand, the role of PPARδand its ligand in gamete formation and function is less well understood. This review will summarize the reproductive functions of PPARδand project its potential applications in assisted reproductive technology.
