Objective: This study aimed to characterize candidates undergo vasectomy in the public health system, Araçatuba- SP and to study related variables. Methods: We surveyed 300 medical patients and vasectomized contacted by telephone to assess several characteristics. The variables analyzed for the study were age, marital status, education, religion, monthly family income and per capita, number of living children, reason for seeking treatment method, contraceptive use, marital relationship quality, decision time (date of intent to perform the procedure) and not because of the procedure. Data were pooled for the analysis of results. Results: The age of the candidates ranged from 23 to 65 years (mean 36.86 years) and average 2.56 living sons. The average monthly family income was R$ 1.079,15, with average per capita income of R$ 249,07. The couple's contraception before the procedure was on account of the woman who used oral anti-conception (84%). The complication rate with the method was around 6.04%, the biggest complication was dehiscence (77.7% of cases of complications), these being mainly during the first 100 cases. Conclusion: Vasectomy is a very effective contraceptive method, with low complication rate and low cost, should be encouraged by the public health system as a means of family planning policy.

Objective: To evaluate the effect of female obesity on the results of In Vitro Fertilization (IVF) in six parameters: dose of gonadotropins required, number of oocytes retrieved and fertilization, pregnancy, miscarriage and live births rates. method: Literature search in PUBMED articles in English between 2008 and 2013 using the following keywords: female, obesity and In Vitro Fertilization. 15 articles were selected for this work. Results: From the total only two articles showed that female obesity does not alter the results of IVF. The remaining 13 came to the conclusion that obesity has a negative effect on some of the parameters evaluated. However, there was no consensus about its effect. Conclusion: Further studies are needed to clarify the real role of obesity in female patients undergoing IVF, but the weight loss prior to treatment should always be encouraged. © odos os direitos reservados a SBRA - Sociedade Brasileira de Reprodução Assistida.

Abstract The aim of this study was to evaluate the influence of patients' lifestyle factors and eating habits on embryo development. A total of 2659 embryos recovered from 269 patients undergoing intracytoplasmic sperm injection cycles were included. The frequency of intake of food items and social habits were registered and its influences on embryo development evaluated. The consumption of cereals, vegetables and fruits positively influenced the embryo quality at the cleavage stage. The quality of the embryo at the cleavage stage was also negatively correlated with the consumption of alcoholic drinks and smoking habits. The consumption of fruits influenced the likelihood of blastocyst formation, which was also positively affected by the consumption of fish. Being on a weight-loss diet and consumption of red meat had a negative influence on the likelihood of blastocyst formation. The likelihood of blastocyst formation was also negatively influenced by the consumption of alcoholic drinks and by smoking habits. The consumption of red meat and body mass index had a negative effect on the implantation rate and the likelihood of pregnancy. In addition, being on a weight-loss diet had a negative influence on implantation rate. Our evidence suggests a possible relationship between environmental factors and ovary biology. © 2015 Reproductive Healthcare Ltd. Source


In order to increase the success rate of in vitro fertilization cycles, several studies have focused on the identification of the embryo with higher implantation potential. Despite recent advances in the reproductive medicine, based on the OMICs technology, routinely applicable methodologies are still needed. Thus, in most fertilization centers embryo selection for transfer is still based on morphological parameters evaluated under light microscopy. Several morphological parameters may be evaluated, ranging from the pronuclear to blastocyst stage. In general, despite the day of transfer, some criteria are suggested to present a predictive value for embryo viability when analyzed independently or combined. However, the subjectivity of morphological evaluation, as well as the wide diversity of embryo classification systems used by different fertilization centers shows contrasting results, making the implementation of a consensus regarding different morphological criteria and their predictive value a difficult task. The optimization of embryo selection represents a large potential to increase treatment success rates, allowing the transfer of a reduced number of embryos and minimizing the risks of multiple pregnancy. © 2015, Federacao Brasileira das Sociedades de Ginecologia e Obstetricia.

Purpose: To identify the correlation between different cycles, patient factors and blastocyst characteristics. Methods: The study included 420 patients undergoing ICSI cycles and 2781 graded blastocysts, which took into account the blastocyst quality. The correlations between the blastocyst parameters and the patient and cycle characteristics were assessed. Results: The blastocyst development was negatively correlated with the maternal age, BMI and dose of FSH. The ICM was negatively correlated with the FSH dose, whereas the TE quality was influenced by the FSH dose, the maternal age and the number of retrieved oocytes. The embryo morphology on days two and three may predict the blastocyst developmental competence. Conclusions: Older patients and patients with high BMI should not be included in extended embryo culture programmes. The extended culture may not favour embryos with poor morphology on days two and three of development. Additionally, a lower ovarian stimulation and decreased oocyte yields may lead to the development of high-quality blastocysts. © 2012 Springer Science+Business Media New York. Source
