“…Our findings disagree with the report of Hughes et al [20] who noted a similar endometrial thickness and morphology in smokers and nonsmokers undergoing IVF. At the same time, it is in accordance with the observed detrimental effect of smoking on endometrial receptivity [6,25]. It is noteworthy that in both our groups, endometrial thickness was above the suggested lower limit, which may explain this negative effect [26].…”

“…Several meta-analyses and reviews have investigated the effect of smoking in patients undergoing IVF treatment [5][6][7]. They all found that compared to nonsmokers, smokers required a higher mean gonadotropin doses for ovarian stimulation, and had lower peak E2 levels, fewer oocytes retrieved, lower fertilization and implantation rates, and lower pregnancy and live-birth rates.…”

“…Surprisingly, however, despite the widespread studies of the effect of smoking on reproductive outcome after IVF treatment [6,[13][14][15][16], there is no information in the literature on the influence of smoking on COH and IUI.…”

Aim To evaluate the influence of smoking on the outcome of COH and IUI in subfertile couples. Patients and methods We reviewed the medical files of all consecutive women, age ≤35 years, attending our infertility clinics over an eigth-year period. Data on patient age, smoking habits, and variable related to infertility-treatment were collected from the files. Results A total of 2,318 cases were evaluated: 1,803 in nonsmoking patients (n=679) and 515 in smokers (n=206). The smokers used significantly more gonadotropin ampoules and gained a thinner endometrium on the day of hCG administration than the nonsmokers (p<0.016 for both). There were no between-groups differences in patient age, duration of gonadotropin stimulation, number of follicle >14 mm in diameter, or E2 levels on the day of hCG administration. Conclusion Smokers undergoing COH with IUI required a significantly higher gonadotropin dosage than nonsmokers in order to achieved a comparable pregnancy rate.

Purpose Environmental influences on reproductive success are recognized. We hypothesized that location of fertility clinics may influence treatment success and explored this hypothesis utilizing donor egg IVF (IVF) embryo transfer (ET) model. Methods Publicly accessible national registry data (Society for Assisted Reproductive Technology) on fresh & frozen (FET) ET cycles undertaken at participating clinics across North America (n=444 IVF centers) for 2007 were utilized. Information on number of donor egg IVF cycles, live birth (LB) rate following fresh and frozen ET(FET), average number (#) of ET and IVF center's location, geographical coordinates (latitude, longitude, altitude), annualized average temperatures and midyear regional ultraviolet B (UVB) radiation intensity were obtained. Multivariable logistic regression analyses assessed relationship between LBR (in tertile and uppermost versus lesser quartiles) following fresh and FET with geographical coordinates (region and altitude of clinic location) and ecological influences (average temperature and midyear UVB intensity), adjusting for #ET and clinic experience with donor egg IVF. Results Average number of fresh ET, clinic location (region) and midyear UVB intensity were positive predictors of LBR following fresh ET, whereas altitude and annualized average regional temperature demonstrated an inverse relationship with LBR following fresh ET. For FET cycles, #ET, clinic region and altitude were positive determinants of increasing LBR's. Annualized regional temperature and midyear UVB failed to demonstrate any relationship with LB following donor egg FET. Conclusion Our data suggest that ecological influences may relate to donor egg IVF cycle success. Future studies are needed to better elucidate the mechanisms that could explain the observed associations.

“…Известно, что у женщин с эндометриозом он менее восприимчив к имплантации эмбриона, чем у женщин без эндоме-триоза [21,28]. Установленное негативное влияние клинических факторов на уменьшение эндометри-альной рецептивности в период окна имплантации, несомненно, способствует снижению фертильности [40]. Другие признаки дисфункции эутопического эндометрия включают: увеличение ангиогенной ак-тивности, повышение активности ароматазы, изме-нение децидуализации, снижение апоптоза и дисре-гуляция избыточного уровня прогестерона [9,12,18,22].…”
