Gamete retrieval in terminal conditions: is it practical? What are the consequences?

There is an increasing interest in, and request for, gamete retrieval from recently deceased or near-dead subjects for the purpose of posthumous procreation. This usually arises in an emergency situation with little time for physicians to consider ethical ramifications. Advance planning is needed to help these physicians make thoughtful decisions. After considering the complexity of the issues involved, the Ethics Consult Service and the Ethics Committee at the University of Virginia requested that we develop a policy on gamete retrieval for subjects in terminal conditions, which would govern and guide involved providers should this process be requested. Our team consisted of members of the Ethics Consult Service and Ethics Committee, as well as personnel who might be intimately involved in the gamete retrieval process, including the director of the Human Gamete and Embryo Laboratory, a urologist, and a reproductive endocrinologist. In addition to reviewing the current literature describing the actual processes involved, we explored the ethical implications of gamete retrieval in these situations. A policy was developed and approved by the Ethics Committee at our institution, and is included in this article.

[Sterility--a woman's concern? Coping behavior and partnership structure of sterile couples of various diagnostic groups].

Three groups of sterile couples with functional, tubal and andrologically caused sterility were compared for the evaluation of sex- and diagnosis-dependent kinds of overcoming of their disease. Anamnestic data, anxiety, the coping strategy of sterility and as well the couple and personality structure are analysed. Independent of the organic cause of sterility the women showed a higher emotional reaction level (anxiety, coping stress) than their husbands. In all groups the "healthy" partners dominate. The subfertile men seem to be more subordinate, less engaged and interested and not so anxious as their wives and as the husbands of tubal sterile women. The healthy women with andrologically caused sterility present a highly emotional engagement in the overcoming and treatment of their disease. Possible emotional mechanisms and social stereotypes of self-presentation are discussed, which may cause the intense engagement of the women independent of the organic cause of sterility.

Luteal phase defects in assisted reproduction: the role of luteal phase supplementation.

Data from literature show that whereas in non-GnRH-a controlled ovarian hyperstimulation cycles luteal phase supplementation is not crucial, its use in GnRH-a/gonadotropins protocols seems to lead to a definite reduction of the negative effects of such drugs. The most important side effect of the hCG use as luteal support is the increased rate of the ovarian hyperstimulation syndrome (OHSS). Therefore its use should be reserved for very selected patients, for those subjects with preovulatory levels of E2 < 2500 pg/ml. As regard the use of progesterone, most authors agree that it has less efficacy than hCG but this depends on the administration route.

Ethical issues in assisted reproduction.

Since the birth of Louise Brown in 1978, no other area in clinical practice and medical research has held the public interest to the same extent as the assisted reproductive technologies. This has led to the formation of committees of enquiry, guidelines from professional bodies, the passage of legislation, and the formation of legislative bodies. The ethical issues which arise in the clinical practice of assisted reproduction, the donation of gametes and embryos, and their cryopreservation, surrogacy, and human embryo research are reviewed.

Current technology of oocyte retrieval.

Transvaginal follicle puncture under sonographic control has become the method of choice for ovum retrieval worldwide. Because it is the current technology of the 1990s, there are very few reports in the literature on other methods of oocyte retrieval. Furthermore, perhaps because of the simplicity of transvaginal follicle puncture under sonographic control, there are only a few reports on the technique itself in the current literature. This review classifies the papers on hand according to general studies of the subject, appropriate anesthesia, necessity of follicle flushing for oocyte retrieval, vaginal disinfection and the evaluation of the risk following transvaginal oocyte retrieval, and new techniques in connection with the harvesting of oocytes.

[Sterility and medically assisted fertilization].

In vitro fertilization is now part of the treatment of infertility. Since 12 years, indication have been extended to male or female infertility factors. The successes have also been increased and the actual pregnancy rate is about 18% pregnancies by retrieval. Different methods are available such as GIFT, ZIFT, TET and progresses will certainly come from new techniques such as micro-manipulation, oocyte freezing and genetic procedures applied to assisted reproduction technologies.
