A womb of his own.

Although some feminists formerly saw utopian possibilities in reproductive technology, many now fear that the new technologies are turning women's bodies into test tubes. They feel that these technologies are designed less to help infertile women than to appease men's envy of women's reproductive power. The consequences of the new technologies for the psychology of women and children and the future creation of culture are open questions. Should the technologies succeed in taking reproduction out of the body altogether, it remains to be seen whether women will gain in freedom, or whether this will simply fulfill the age-old misogynistic fantasy of depriving women of their central place in procreation.

[Sexuality. A freudian psychoanalytical concept].

Emphasis is placed in the difficulty in conceptualizing sexuality as a complex and controversial subject. This is a presentation of a concept based on freudian psychoanalysis. With this in mind, many of Freud's references are collected from the Brazilian Standard Edition of the Complete Psychological Works of Sigmund Freud. The following concept is arrived at: sexuality is an instinctive vital energy directed to pleasure, with the possibility of quantitative and qualitative variations, closely bound to homeostasis, to affection, to social relations, to phases of development of childhood-libido, to eroticism, to genitality, to sexual relations, to procreation and to sublimation.

[Cystic fibrosis in adults].

One third of patients with cystic fibrosis are adults. The respiratory disease, which conditions the vital prognosis, consists of bronchiectasis with chronic bronchial infection and bursts of acute infection, leading to respiratory insufficiency. Pseudomonas aeruginosa is the most frequent bacteria in adulthood. Exocrine pancreatic insufficiency is associated in 80% of patients. Some complications, such as diabetes, hepatic cirrhosis or osteoporosis, are more frequent in adults. Treatment is based on chest physiotherapy and antibiotics with intravenous courses when there is a colonisation with P. aeruginosa. Pregnancy can be considered in women when respiratory and nutritional status is acceptable. Men are sterile because of congenital bilateral atresia of vas deferens, but can be proposed medical assistance for procreation.

Surrogate motherhood.

A "surrogate mother" is a woman who, for financial or other reasons, agrees to bear a child for another woman who is incapable to conceive herself. In other words, she is a "substitute mother" that conceives, gestates and delivers a baby on behalf of another woman who is subsequently to be seen as the "real" (social and legal) mother of the child. Though the practice of surrogacy has already become a big market in western countries, it has also generated countless challenges for the law because it adds a third dimension to the meaning of motherhood. Like adoption, surrogacy separates the role of rearing mother from what the law has called the natural mother, but gestational surrogacy breaks the latter down into the roles of genetic mother and birth mother, leaving two women with biological connections to the child. Because surrogacy tends to commodify and dehumanize people, and because of all its legal, social, and psychological complications, it is obviously not wise to accept surrogacy as an alternative way of procreation.

[Laparoscopic diagnosis of endometriosis].

Our study centred on the research of Pelvic Endometriosis prevalence, in 134 women, who were submitted to diagnostic or surgical laparoscopy in our department, from April 1991 to November 1994. According to the admission causes, the women were divided in four groups: Pelvic pain/infertility/Anexial tumours/Optional tubal sterilization. The study covered an analysis of the relationships between the groups and the women's mean age, the contraception methods, parity, clinical data, laparoscopic findings and the percentage of endometriotic signs in each group. Although we did not have many cases, the endometriosis rate found in the different groups was identical to that described in many articles published worldwide. We confirmed that it is necessary to have a suspicious attitude without arguing the need for diagnostic laparoscopy every time a woman, in fertile age, has pelvic pain interfering with her quality of life, either socioprofessional, sexual or procreative.

The ethics of therapeutic and reproductive human cloning.

Neither therapeutic cloning nor reproductive cloning necessarily pose insurmountable ethical obstacles. Two defences of therapeutic cloning are considered. The first defence, the argument from property, is rejected because it entails morally counter-intuitive consequences. We should prefer a 'balance of reasons' defence which leaves room for the view that human life has intrinsic value. Reproductive cloning is best defended by an appeal to the right to procreative autonomy. The sorts of harms it is feared clones will suffer are also suffered by children conceived through natural means, even when these harms were preventable. The right to reproductive autonomy disallows state control of any form of reproduction for the reasons of child welfare discussed.

[Luliberin and lutropin--their significance].

Human lutropin (hLH) is a heterodimeric, glycoprotein hormone released from pituitary by decapeptide luliberin (LH-RH). The both hormones plays an important role in axis hypothalamus-pituitary-gonads responsible for procreation. Many isoforms of hLH have been found and the occurrence of several genetic variants of the hormone in infertile female patients were described. Also genetic mutants of human lutropin choriogonadotropin receptor (LH/CG-R) in male young patients with precocious puberty were proved. Until now several thousands of LH-RH analogs were synthesized and some of them were applied in therapy of several gynecological, and oncological diseases or in vitro fertilization.

Feminist critiques of new fertility technologies: implications for social policy.

This essay aims to show how feminist theoretical and practical perspective have enriched and deepened debate about moral and social issues generated by the proliferation and commodification of new reproductive techniques. It evaluates alternative feminist appraisals beginning with the first group to organize a collective response to the medicalization of infertility and explores several weaknesses working within their assessment: objectification of infertile women, naturalizing constructions of motherhood, hostility to technology, and an overly simplistic conception of power relations. Next, it shows how subsequent feminists have reframed the issues to overcome these weaknesses, drawing on themes prominent in recent theoretical debates: the need to reclaim women's agency, to revalue mothering, and to reappraise power relations. Lastly, it weighs the prospects for a collaborative politics that is sensitive to the social marginalization of vulnerable women and suggests practical strategies for responding to mounting pressures to procreate at any price.

[Oocyte maturation. From animal experiments to human reproduction techniques].

The control of the oocyte growth and maturation are complex processus implicating endocrines (gonadotropines) and paracrine factors (growth factors, cytokines, steroids...), the paracrine regulation being under the endocrine control. The control of the cytoplasmic and nuclear maturation is realized by substances going through gap junctions from the follicular cells to the oocyte. Two of these substances, which are present in the follicular fluid, are responsible for maintaining the meiotic arrest: cyclic AMP and purines. Hormones or growth factors, which are able to affect the oocyte maturation both in vivo and in vitro, when they interact with their receptors stimulate enzymes which in turn stimulate the release of second messengers. Actually, the whole process that is oocyte maturation followed by fertilization in vitro does not give good results. This difficulty does not permit yet the freezing of immature oocytes which could be a solution in some cases encountered in Medically Assisted Procreation.
