Do útero à adoção: a experiência de mulheres férteis que adotaram uma criança

Even with all changes and ruptures related to the social roles that woman had performed, the literature had confirmed that the motherhood still configures it like one of the main roles that she hopes to play in some moment of her life. When the woman did not get pregnant or take ahead a pregnancy, some women find in adoption an alternative to play this role. This research aimed to understand the experience of being mother for adoption in the case of fertile women, but whose partner is infertile. Supported by existential-phenomenological theory, used it the narrative, how methodological instrument. Participated five women, whose adoption process followed the legal ways in the Youngness and Infancy Judgeship of Natal/RN. The results showed that in the selfish training, the woman to see herself how whose role principal is to generate children, although, she think that is natural her participation in others activities go out home too. In male infertile case is a tendency that the woman strikes the infertile status too. The adoption is an alternative to fulfill her desire of being a mother and, meanwhile, please her husband and guarantee the continuity of her love relationship. Through motherly care, the woman discover herself as a mother, what brings a new meaning for her live, independent of to generate a child. Though, exit frustration, sometimes, in association with suffering, on account of the pregnancy and childbirth absence. The end of the research suggests reflections that to become fulfilled herself as mother, the woman does not need, necessarily, to generate a child, being the maternity one of the uncountable possibilities that are shown, and that she can choose, or not, accomplish it

Male Homosexuality in Brazilian Indexing Languages: Some Ethical Questions

Studies on ethics in information organization have deeply contributed to the recognition of the social dimension of Information Science. The subject approach to information is linked to an ethical dimension because one of its major concerns is related to its reliability and usefulness in a specific discursive community or knowledge domain. In this direction, we propose, through an exploratory research design with qualitative and inductive characteristics, to identify the specific terminology that Brazilian indexing languages allow for terms relating to male homosexuality. We also analyzed the terms assigned to papers published in the Journal of Homosexuality, Sexualities and Journal of Gay & Lesbian Mental Health between the years 2005 to 2009. From this analysis of terms and the Brazilian indexing languages, we see (1) the Brazilian context, (2) imprecision in the terminology, (3) indications of prejudices disseminated by political correctness, (4) biased representation of the subject matter, (5) and the presence of figures of speech.

Intracytoplasmic morphologically selected sperm injection benefits for patients with oligoasthenozoospermia according to the 2010 World Health Organization reference values

The comparison between the outcomes of intracytoplasmic morphologically selected sperm injection performed in couples with male factor infertility according to the World Health Organization guidelines from 1999 and 2010 was the objective of this study. Our results suggest that the sperm selection under high magnification results in improved treatment outcomes in patients with oligoasthenoteratozoospermia, according to the new World Health Organization guidelines.

Evaluation of N-acetilglucosaminidase and myeloperoxidase activity in patients with endometriosis-related infertility undergoing intracytoplasmic sperm injection

Aim: Inflammation is as an important factor in ovulation with the active participation of leucocytes and their inflammatory mediators. The present study was performed to compare the activity of the inflammatory enzymes myeloperoxidase (MPO) and N-acetylglucosaminidase (NAG) in patients with endometriosis-related infertility and in normally ovulating women undergoing intracytoplasmic sperm injection (ICSI).Material and Methods: This prospective study included infertile women undergoing ICSI treatment. These women were divided into two groups: endometriosis anovulation (n = 18) and normally ovulating (n = 20). NAG and MPO activity was evaluated colorimetrically in serum and in follicular fluids obtained at the time of oocyte retrieval.Results: There was a significant correlation between the serum and follicular fluid activities of NAG and MPO (tau = 0.256, P = 0.025; and tau = -0.234, P = 0.041; respectively). Both serum and follicular fluid NAG activities were higher in patients with endometriosis compared to the control group (P < 0.001). MPO follicular fluid activity was lower in patients with endometriosis compared to normally ovulating women (P = 0.016).Conclusion: Infertile patients with endometriosis show a distinct pattern of serum and follicular fluid macrophage/neutrophil activation compared to normally ovulating women undergoing ICSI, which may reflect the role of immune and inflammatory alterations in endometriosis-related infertility.

Pregnancy outcomes in women with repeated implantation failures after intracytoplasmic morphologically selected sperm injection (IMSI)

Background: The purpose of this study was to compare laboratory and clinical outcomes of intracytoplasmic morphologically selected sperm injection (IMSI) and conventional intracytoplasmic sperm injection (ICSI) in couples with repeated implantation failures.Methods: A total of 200 couples with at least two prior unsuccessful ICSI cycles were enrolled: 100 couples were submitted to IMSI and 100 were submitted to routine ICSI. For IMSI, spermatozoa were selected at 8400x magnification using an inverted microscope equipped with Nomarski (differential interference contrast) optics. For conventional ICSI, spermatozoa were selected at 400x magnification. Clinical outcomes were evaluated between the two groups.Results: Study patients were comparable in age, number of treatment failures, aetiology of infertility, percentage of normal form assessed by MSOME (motile sperm organelle morphology examination), semen parameters, total number of oocytes collected, number of mature oocytes collected, total number of embryos transferred and number of high-quality embryos transferred. No statistically significant differences between the two groups were observed with regard to rates of fertilisation, implantation and pregnancy/cycle. Although not statistically significant, rates of miscarriage (IMSI:15.3% vs ICSI:31.7%), ongoing pregnancy (IMSI:22% vs ICSI:13%) and live births (IMSI:21% vs ICSI:12%) showed a trend towards better outcomes in the IMSI group. In addition, analysis of subpopulations with or without male factor showed similar results.Conclusions: Our results suggest that IMSI does not provide a significant improvement in clinical outcome compared to ICSI, at least in couples with repeated implantation failures after conventional ICSI. However, it should be noted that there were clear trends for lower miscarriage rates (approximate to 50% reduced) and higher rates of ongoing pregnancy and live births (both nearly doubled) within the IMSI group. Further confirmation as well as randomized large-scale trials are needed to confirm the beneficial effects of IMSI in couples with poor reproductive prognoses.

Infiltrating CD8(+) T lymphocytes, natural killer cells, and expression of IL-10 and TGF-beta 1 in chemically induced neoplasms in male Wistar rats

The present study aimed to estimate the number of CD8(+) T and natural killer (NK) infiltrating cells and the expression of interleukin-10 (IL-10) and transforming growth factor beta 1 (TGF-beta1) in chemically induced neoplasms in an initiation-promotion bioassay for carcinogenesis. Male Wistar rats were treated with N-nitrosodiethylamine, N-methyl-N-nitrosourea, N-butyl-N-(4-hydroxybutyl) nitrosamine, dihydroxy-di-N-propylnitrosamine, and 1,2-dimethylhydrazine for 4 weeks. Two groups were subsequently exposed through diet to phenobarbital (0.05%) or 2-acetylaminofluorene (0.01%) for 25 weeks. An untreated group was used as a control. Immune cells and cytokines were immunohistochemically evaluated in neoplasms and in surrounding normal tissues at the liver, kidneys, lung, and small and large intestines. When compared to the respective normal tissues, an increased number of NK cells was verified infiltrating the colon, lung, and kidney neoplasms, while the number of CD8+ T cells decreased in the intestine and lung neoplasms. Expression of IL-10 was found mainly in kidney tumors. TGF-beta1 was expressed mainly in the liver and kidneys tumors. The results indicate that the differential occurrence of immune cells between neoplastic and normal tissues could be dependent upon tumor microenvironment.
