The frequency of chromosome aberration in spontaneous and induced abortions in the first three-month period of pregnancy has been presented in this study. The examination has been done in the period from 2001 till 2002 on the sample of 80 chorion and fetal tissue of 8-12 weeks of gestation.
This article discusses the nature of infertility treatment and its relation to infertile couples' desires for multiple pregnancy, the special risks of iatrogenic multiple pregnancy (IMP), the informed consent process in assisted reproductive technology, and the ethical dilemma of IMP and methods for its resolution.
UK fertility experts have sounded a note of cautious optimism about the safety of preserving ovarian tissue and transplanting it back into women after cancer treatment.
A 35-year-old nulliparous woman with a giant uterine myoma is described. During the past three years she had developed a intramural myoma and a subserous myoma. Although the lesions were excised, both reappeared and were treated with GnRH analogues for 6 months.
Telemedicine is the electronic transmission of health information for the delivery of clinical care from a distance. Today it is increasingly used to provide efficiencies in the delivery of women’s health care.
Over the past two decades, an epidemic of multiple pregnancies has taken place in the developed world due to the widespread use of assisted reproductive technology. The general public has come to accept the phenomenon of higher order multiple as being a normal occurrence, expecting a good outcome for both the fetuses and the mother.
Uteroplacental Bleeding Disorders During Pregnancy: Do Missing Paternal Characteristics Influence Risk?
Patients suffering from diseased and injured organs may be treated with transplanted organs. However, there is a severe shortage of donor organs which is worsening yearly due to the aging population. Scientists in the field of tissue engineering apply the principles of cell transplantation, materials science, and bioengineering to construct biological substitutes that will restore and maintain normal function in diseased and injured tissues.
Molecular Mechanisms in Uterine Epithelium during Trophoblast Binding:The Role of Small GTPase RhoA in Human Uterine Ishikawa Cells
The sperm penetration assay (SPA) is used to predict the fertilizing capacity of sperm. Thus, some programs rely on SPA scores to formulate insemination plans in conjunction with in-vitro fertilization (IVF) cycles. The purpose of this study was to evaluate if a relationship exists between SPA scores and polyspermy rates during conventional IVF cycles.
About 30–40% of male infertility is due to unknown reasons. Genetic contributions to the disruption of spermatogenesis are suggested and amongst the genetic factors studied, Y chromosome microdeletions represent the most common one. Screening for microdeletions in AZFa, b and c region of Y chromosome showed a big variation among different studies.
The publication of a report in Nature in 2004 by the Tilly group suggesting that mouse ovaries are capable of generating oocytes de novo post-natally, has sparked interest in a problem long thought to have been resolved from classical studies in a variety of mammalian species.
Cervical cancer is the second most common gynecological cancer amongst women world-wide. Despite optimized protocols, standard treatments still face several disadvantages. Therefore, research aims at the development of immune-based strategies using tumor antigen-loaded dendritic cells for the induction of cellular anti-tumor immunity.
The safety and tolerability of a new highly purified, urine-derived human menopausal gonadotropin (hMG) preparation [Menopur(R)] was compared with a currently available hMG [Repronex (R)] in women undergoing in vitro fertilization (IVF).
Evidence supporting a role for estrogen in male reproductive tract development and function has been collected from rodents and humans. These studies fall into three categories: i) localization of aromatase and the target protein for estrogen (ER-alpha and ER-beta) in tissues of the reproductive tract; ii) analysis of testicular phenotypes in transgenic mice deficient in aromatase, ER-alpha and/or ER-beta gene; and, iii) investigation of the effects of environmental chemicals on male reproduction.
Central to any consideration of techniques in the IVF lab is the quality of the gametes that the lab has to work with. Usually there is little opportunity to modify the basic quality of sperm, however, the oocyte is a direct biological end product of ovarian super-ovulation as commonly conducted in human IVF therapy.
Plasma Homocysteine, Fasting Insulin, and Serum Androgens as a Function of Sonographic Ovarian Features in Women Feferred for Infertility Assessement
The first thing that usually comes to mind when people hear the term, "infertility treatment," is the risk of multiple births. This worry has been fueled by the recent highly publicized multiple births in Iowa and Texas.
Our guest editor for this issue of Gynaecology Forum is Hans van der Slikke, who was also guest editor for the last issue of Gynaecology Forum concerned with the Internet in 2000. I typed that editorial on my PC and emailed the draft to the publishers.
Much has changed in the World Wide Web in the 3 years since the first Internet issue of Gynaecology Forum (www.obgyn.net/medforum.asp) was published in September 2000. At that time it was still necessary to cover the history of the Internet and explain the requirements needed to access it.
Suppose you want to find a good website about gynaecology and/or obstetrics and you try the search engine Google, you will get 1,060,000 hits for gynaecology and 1,260,000 for obstetrics. Both give as the first link www.obgyn.net, ‘the Universe of Women’s Health’.
Jorge Amado, a Brazilian writer, once remarked: ‘The common bond in Latin America is poverty; there are very few cultural bonds’.
The Internet has, without question, assumed a place in the life of most physicians and many patients. Though users vary in skill of use and sophistication of inquiry, some issues are common to all. The quandary about which websites may safely be trusted is one such issue. Health website quality guidelines, easily accessed on the Internet, aid users in their decisions.
In 1935 Drs Stein and Leventhal described 7 women with irregular periods (oligomenorrhea), increased body hair (hirsutism) and obesity, who at the time of surgery were found to have enlarged ovaries with a smooth "pearly white" appearance.
The ubiquitous use of the World Wide Web to facilitate learning has been a benefactor of change, revolutionising the way in which education can be delivered and received. This technological advancement has woven together communities of learners and permitted access to huge repositories of information while eliminating distance as an obstacle to learning (Table I).
