What is it to practise good medical ethics? A Muslim's perspective.

Good medical ethics should aim at ensuring that all human beings enjoy the highest attainable standard of health. With the development of medical technology and health services, it became necessary to expand the four basic principles of medical ethics and link them to human rights. Despite the claim of the universality of those ethical principles, their perception and application in healthcare services are inevitably influenced by the religious background of the societies in which those services are provided. This paper highlights the methodology and principles employed by Muslim jurists in deriving rulings in the field of medical ethics, and it explains how ethical principles are interpreted through the lens of Islamic theory. The author explains how, as a Muslim obstetrician-gynaecologist with a special interest in medical ethics, including international consideration of reproductive ethics issues, he attempts to 'practise good medical ethics' by applying internationally accepted ethical principles in various healthcare contexts, in ways that are consistent with Islamic principles, and he identifies the evidence supporting his approach. He argues that healthcare providers have a right to respect for their conscientious convictions regarding both undertaking and not undertaking the delivery of lawful procedures. However, he also argues that withholding evidence-based medical services based on the conscientious objection of the healthcare provider is unethical as patients have the right to be referred to services providing such treatment.

Ethical issues in human reproduction: Islamic perspectives.

Sexual and reproductive rights of women are essential components of human rights. They should never be transferred, renounced or denied for any reason based on race, religion, origin, political opinion or economic conditions. Women have the right to the highest attainable standard of health care for all aspects of their reproductive and sexual health (RSH). The principle of autonomy emphasizes the important role of women in the decision-making. Choices of women in reproduction, after providing evidence based information, should be respected. Risks, benefits and alternatives should be clearly explained before they make their free informed consent. Justice requires that all be treated with equal standard and have equal access to their health needs without discrimination or coercion. When resources are limited there is tension between the principle of justice and utility. Islamic perspectives of bioethics are influenced by primary Sharia namely the Holy Quran, authenticated traditions and saying of the Profit Mohamed (PBUH), Igmaa and Kias (analogy). All the contemporary ethical principles are emphasized in Islamic Shariaa, thus these principles should be observed when providing reproductive and sexual health services for Muslim families or communities. The Family is the basic unit in Islam. Safe motherhood, family planning, and quality reproductive and sexual health information and services and assisted reproductive technology are all encouraged within the frame of marriage. While the Shiaa sect permits egg donation, and surrogacy the Sunni sect forbids a third party contribution to reproduction. Harmful practices in RSH as FGM, child marriage and adolescent pregnancy are prohibited in Islam. Conscientious objection to treatment should not refrain the physician from appropriate referral.

Islamic perspectives in human reproduction.

Assisted reproductive technology is widely practised around the world for the treatment of virtually all forms of infertility. The application of this technology in the Islamic world had been delayed for many years, based on the misconception that Islamic teachings do not approve assisted reproduction. The paper discusses derivation of Islamic rulings and its impact on the ethics of contemporary issues, including family formation and assisted reproduction. It clearly shows that Islam encourages family formation and assisted reproduction, when indicated, within the frame of marriage. It also discusses differences among Muslim sects, Sunni and Shi'aa. The paper also discusses Islamic rulings on the new emerging practices in assisted reproduction, including surrogacy, multifetal pregnancy reduction, cryopreservation, pregnancy in the post-menopausal period, sex selection and embryo implantation following the husband's death. The moral status of the embryo in Islam is discussed. Organ differentiation and ensoulment are believed to occur at 42 days after fertilization at the earliest. As individuation of the embryo does not occur before 14 days from fertilization, research on surplus embryos during this period is allowed. Similarly, preimplantation genetic diagnosis, gene therapy and non-reproductive cloning for the benefit of humanity are ethically acceptable in Islam. This information should help physicians in their decision before conscientious objection to offering various modalities of assisted reproduction to their infertile patients.

Sex selection: treating different cases differently.

This paper contrasts ethical approaches to sex selection in countries where discrimination against women is pervasive, resulting in selection against girl children, and in countries where there is less general discrimination and couples do not prefer children of either sex. National sex ratio imbalances where discrimination against women is common have resulted in laws and policies, such as in India and China, to deter and prevent sex selection. Birth ratios of children can be affected by techniques of prenatal sex determination and abortion, preconception sex selection and discarding disfavored embryos, and prefertilization sperm sorting, when disfavored sperm remain unused. Incentives for son preference are reviewed, and laws and policies to prevent sex selection are explained. The elimination of social, economic and other discrimination against women is urged to redress sex selection against girl children. Where there is no general selection against girl children, sex selection can be allowed to assist families that want children of both sexes.

Number of embryos for transfer following in-vitro fertilisation or intra-cytoplasmic sperm injection.

BACKGROUND: The traditional reliance on the transfer of multiple embryos during in vitro fertilisation (IVF) in order to maximise the chance of pregnancy, has resulted in increasing rates of multiple pregnancies. Women undergoing IVF had a 20 - fold increased risk of twins and 400 - fold increased risk of higher order pregnancies (Martin 1998). The maternal and perinatal morbidity and mortality as well as national health service costs associated with multiple pregnancies is significantly high in comparison with singleton births (Luke 1992; Callahan 1994; Goldfarb 1996). Single embryo transfer is now being considered as an effective means of reducing this iatrogenic complication. This systematic review evaluates the effectiveness of elective two embryo transfer in comparison with single and more than two embryo transfer following IVF and ICSI (intra cytoplasmic sperm injection) treatment. OBJECTIVES: The aim of this review is to determine, whether in couples who undergo IVF/ICSI: (1) the elective transfer of two embryos improves the probability of livebirth compared with: (a) Single embryo transfer, (b) Three embryo transfer or (c) Four embryo transfer.(2) the elective transfer of three embryos improves the probability of livebirth compared with: (a) Single embryo transfer, or (b) Four embryo transfer, SEARCH STRATEGY: We searched the Cochrane Menstrual Disorders and Subfertility Group's trials register (searched June 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2003), MEDLINE (1970 to 2003), EMBASE (1985 to 2003) and reference lists of articles. We also handsearched relevant conference proceedings and contacted researchers in the field. SELECTION CRITERIA: Only randomised controlled trials were included. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed eligibility and quality of trials. MAIN RESULTS: We found no studies that compared a policy of transferring multiple embryos on one cycle versus a policy of cryo- preservation and transfer of a single embryo over multiple cycles. We also found no trials comparing transfer of two versus three embryos. Three small, poorly reported trials compared transfer of two versus one embryo in a single cycle, and one small, poorly reported trial compared transfer of two versus four embryos in a single cycle. The clinical pregnancy rate per woman/couple associated with two embryo transfer was significantly higher compared to single embryo transfer (OR 2.08, 95% CI 1.24 to 3.50; test for overall effect p = 0.006). The live birth rate per woman/couple associated with two embryo transfer was also significantly higher than that associated with single embryo transfer (OR 1.90, 95% CI 1.12 to 3.22, test for overall effect p=0.02). The multiple pregnancy rate was significantly lower in women who had single embryo transfer (OR 9.97, 95% CI 2.61 to 38.19; p = 0.0008). The effectiveness of double embryo transfer versus four embryo transfer was tested in a single trial. There was no statistically significant differences in the clinical pregnancy rate (OR 0.75, 95% CI 0.26 to 2.16; p=0.6), and multiple pregnancy rates (OR 0.44. 95% CI 0.10 to 1.97; p = 0.28) between the two groups. The livebirth rate in the four embryo transfer group was higher compared to the two embryo transfer group, but the results were not statistically significant (OR 0.35, 95% CI 0.11 to 1.05; p = 0.06). REVIEWERS' CONCLUSIONS: The results of this systematic review suggest that live birth and pregnancy rates following single embryo transfer are lower than those following double embryo transfer as are the chances of multiple pregnancy including twins. As such, it is unlikely that the conclusions are robust enough to catalyse a change in clinical practice. The studies included are limited by their small sample size, so that even large differences might be hidden. Cumulative livebirth rates are seldom reported. The data were inadequate to draw conclusions about single embryo transfer and first frozen single embryo transfer (1FZET) or subsequent single frozen embryo transfers. Until more evidence is available single embryo transfer may not be the preferred choice for all patients undergoing IVF/ICSI. Clinicians may need to individualise protocols for couples based on their risks of multiple pregnancy. A definitive pragmatic, large multi centre randomised controlled trial comparing single embryo versus double embryo transfer in terms of clinical and cost effectiveness as well as acceptability is required. The primary outcome measured should be cumulative livebirth per woman/couple.

Ethics in medical information and advertising.

This article presents findings and recommendations of an international conference held in Cairo, Egypt in 2003 concerning issues of ethical practice in how information is provided to and by medical practitioners. Professional advertising to practitioners and the public is necessary, but should exclude misrepresentation of qualifications, resources, and authorship of research papers. Medical institutions are responsible for how staff members present themselves, and their institutions. Medical associations, both governmental licensing authorities and voluntary societies, have powers and responsibilities to monitor professional advertisement to defend the public interest against deception. Medical journals bear duties to ensure authenticity of authorship and integrity in published papers, and the scientific basis of commercial advertisers' claims. A mounting concern is authors' conflict of interest. Mass newsmedia must ensure accuracy and proportionality in reporting scientific developments, and product manufacturers must observe truth in advertising, particularly in Direct-to-Consumer advertising. Consumer protection by government agencies is a continuing responsibility.

Spontaneous intrauterine pregnancy following salpingectomy for a unilateral hydrosalpinx.

The effect of salpingectomy for unilateral hydrosalpinx with a contralateral normal tube was evaluated in two infertile patients in which unilateral hydrosalpinx, visualized by vaginal ultrasound, was treated by unilateral salpingectomy as a preparatory step before IVF. Spontaneous pregnancy occurred in both patients while waiting to be enrolled in an IVF trial. In conclusion, unilateral salpingectomy for hydrosalpinx in the presence of a contralateral healthy tube could result in spontaneous pregnancy.

Assisted reproduction developments in the Islamic world.

A November 2000 workshop organized by the International Islamic Center for Population Studies and Research, Al-Azhar University, Cairo, considered use of assisted reproduction technologies (ART) in the Islamic world. The workshop reinforced a 1997 recommendation that a Standing Committee for Shari'a Medical Ethics be constituted to monitor and assess developments in ART practice. Among issues the workshop addressed were equitable access to services for infertile couples of modest means, and regulation of standards of equipment and personnel that ART centers should satisfy to gain approval to offer services. Acceptable uses of preimplantation genetic diagnosis were proposed, and follicular maturation research in animals, including in vitro maturation and in vitro growth of oocytes, was encouraged, leading to human applications. Embryo implantation following a husband's death, induced postmenopausal pregnancy, uterine transplantation and gene therapy were addressed and human reproductive cloning condemned, but cloning human embryos for stem cell research was considered acceptable.

Controversies in the surgical management of hydrosalpinx.

The surgical management of hydrosalpinges is a controversial subject. Chronic pathology of the fallopian tube with distal obstruction leads to the formation of a hydrosalpinx, and is associated with very poor pregnancy rates after surgery. In these cases, in-vitro fertilization has proved to be a much better alternative. However, several studies have shown that patients with hydrosalpinges have significantly lower pregnancy and implantation rates after in-vitro fertilization compared with patients with other forms of tubal damage. The exact mechanism by which the hydrosalpinx adversely affects in-vitro fertilization results is not yet fully understood. The value of performing a salpingectomy before in-vitro fertilization has been studied extensively. Currently, a clear benefit in salpingectomies has been proved for patients with ultrasonically visible hydrosalpinges.

Transfer of zona-free embryos improves outcome in poor prognosis patients: a prospective randomized controlled study.

Assisted zona hatching (AZH) has been used in IVF programmes for several years. Recently one group has reported successful pregnancies after transfer of zona-free blastocysts. The aim of our study was to evaluate outcomes after transfer of zona-free day 3 embryos. Two groups of women undergoing intracytoplasmic sperm injection (ICSI) were included in the study. Group A consisted of 52 women under the age of 40 years undergoing their first ICSI attempt. They were alternately randomized to receive zona-free embryos (27 women) and zona-intact embryos (25 women). The second group (group B) included 71 women with a poor prognosis, as defined by age 40 years or more, and/or at least two previous failed IVF/ICSI attempts. They were randomized in a 3:4 ratio (30 zona-free, 41 zona-intact). Acid Tyrode's solution was used to remove the zona pellucida before embryo transfer on day 3 after oocyte collection. The pregnancy rate in group A was not significantly improved when the zona pellucida was removed. However, in the poor prognosis group B, zona removal resulted in a significantly higher pregnancy rate when compared with controls (23 versus 7.3%). We conclude that complete removal of the zona pellucida can improve pregnancy rates in women with poor IVF/ICSI prognosis.

Elevated levels of interleukin-2, soluble interleukin-2 receptor alpha, interleukin-6, soluble interleukin-6 receptor and vascular endothelial growth factor in serum and ascitic fluid of patients with severe ovarian hyperstimulation syndrome.

OBJECTIVE: To investigate the possible role of vascular endothelial growth factor, interleukin-2, soluble interleukin-2 receptor alpha, interleukin-6 and soluble interleukin-6 receptor in the pathogenesis of ovarian hyperstimulation syndrome. STUDY DESIGN: The study group consisted of 10 healthy women who developed severe ovarian hyperstimulation syndrome, group A (n=10), following ovarian stimulation by long GnRHa/hMG protocol for IVF. A control group B=10 patients underwent stimulation with the same protocol and did not develop OHSS. Blood and ascitic fluid samples were assayed for VEGF, IL-2, sIL-2Ralpha, IL-6 and sIL-6R by ELISA. RESULTS: The mean serum levels of IL-2, sIL-2Ralpha, IL-6, sIL-6R and VEGF in OHSS group were 297.5+/-190, 6588+/-5566, 40.6+/-16.6, 5280+/-3326 and 492+/-165 pg/ml as compared to 50.8+/-17.4, 1100+/-391.6, 8.5+/-3.5, 516+/-342 and 167+/-31.3 pg/ml in the control group, respectively, P<0.001. The mean ascitic fluid IL-2, sIL-2Ralpha, IL-6, sIL-6R and VEGF in the OHSS group were 282.5+/-191.5 pg/ml, 26020+/-13 995, 90.5+/-36, 14900+/-2789 and 660+/-359 pg/ml as compared to 32+/-14.8, 1206+/-429.4, 12.6+/-1.7, 614+/-240 and 151+/-20.5 pg/ml, respectively, P<0.001. CONCLUSIONS: The significantly high levels of VEGF in patients with severe OHSS suggest that VEGF is a major capillary permeability agent in OHSS. Elevated levels of IL-6 in serum and peritoneal fluid support the hypothesis that IL-6 may serve as a marker of OHSS. Although serum and ascitic fluid levels of IL-2 were elevated, accumulating evidence does not support a pivotal role for IL-2 in the pathogenesis of OHSS. However, it may have a peripheral role in mediating an increase in vascular permeability. Soluble IL-2Ralpha and sIL-6R may be considered to be involved in OHSS. However, the patho-physiologic mechanism is the subject of further investigations. Clinical application of VEGF-receptors in the management of OHSS is awaited with interest.

Management of long-standing unexplained infertility: A prospective study.

OBJECTIVE: Our purpose was to evaluate a protocol for the management of long-standing unexplained infertility. STUDY DESIGN: A prospective study was conducted at an in vitro fertilization-embryo transfer center with 485 patients with the diagnosis of long-standing unexplained infertility. Patients were treated by means of controlled ovarian hyperstimulation and intrauterine insemination for a maximum of 3 cycles. Those who did not become pregnant underwent in vitro fertilization and intracytoplasmic sperm injection on sibling oocytes. RESULTS: Among 485 patients, 921 cycles of controlled ovarian hyperstimulation and intrauterine insemination were performed. The pregnancy rate was 15.7% per cycle and 29.8% per patient. Among those who did not become pregnant, 131 patients underwent in vitro fertilization and intracytoplasmic sperm injection into sibling oocytes; 48 women became pregnant (36.7%). There was total failure of the in vitro fertilization oocytes in 23 cycles (17.6%). CONCLUSION: Management of long-standing unexplained infertility with controlled ovarian hyperstimulation and intrauterine insemination resulted in a reasonable pregnancy rate. Treatment by means of in vitro fertilization and intracytoplasmic sperm injection into sibling oocytes among patients who did not become pregnant resulted in a good pregnancy rate. The overall results showed that the proposed protocol for management of unexplained infertility is satisfactory.

Multifetal pregnancy reduction: modification of the technique and analysis of the outcome.

OBJECTIVE: To modify the technique of multifetal pregnancy reduction and to study the outcome of reduced twins in comparison with nonreduced twins and high-order multiple gestations. DESIGN: Prospective controlled study. SETTING: The Egyptian IVF-ET Center, Cairo. PATIENT(S): Seventy-five patients with high-order multiple pregnancies resulting from assisted reproduction. Controls were 40 nonreduced twin pregnancies and 22 high-order multiple gestations. INTERVENTION(S): Transvaginal ultrasonically guided multifetal pregnancy reduction was performed. The first 30 cases were done using KCl as a cardiotoxic agent. The modified technique was used for the last 45 cases at an earlier gestational age (approximately 7 weeks) by eliminating the use of KCI and by aspirating the embryonic parts. MAIN OUTCOME MEASURE(S): Miscarriage rate, gestational age at delivery, birth weight, and pregnancy complications. RESULT(S): Using the modified technique, the miscarriage rate was 8.8% and 41 patients delivered between 32 and 39 weeks of gestation (mean+/-SD, 36.9+/-2.45 weeks). The mean (+/-SD) birth weight was 2,450.51+/-235.44 g. The miscarriage rate, fetal wastage rate, mean gestational age, and mean birth weight were similar in reduced and nonreduced twins and were significantly better than in nonreduced triplets and quadruplets. CONCLUSION(S): The modified technique of multifetal pregnancy reduction significantly improved outcomes, which were similar to those of nonreduced twins resulting from assisted reproduction and significantly better than those of nonreduced triplets and quadruplets.

Elevated concentrations of angiogenin in serum and ascitic fluid from patients with severe ovarian hyperstimulation syndrome.

This study was conducted to investigate the possible role of angiogenin in the pathogenesis of ovarian hyperstimulation syndrome (OHSS). The study group consisted of 10 healthy women who developed severe OHSS (group A) following ovarian stimulation by a long protocol of gonadotrophin-releasing hormone analogues/human menopausal gonadotrophin for in-vitro fertilization. A control group B (n = 10) underwent stimulation by the same protocol and did not develop OHSS. Blood samples were taken from group A on day of admission to hospital for treatment of OHSS and, in group B, 1 week after oocyte retrieval. In group A, ascitic fluid was routinely aspirated as a treatment for severe OHSS, and a peritoneal fluid sample was aspirated transvaginally before oocyte retrieval in group B. In group A, the mean serum angiogenin, the mean ascitic fluid angiogenin, the mean serum oestradiol concentration on day of human chorionic gonadotrophin and the mean haematocrit were 8390 +/- 6836 ng/ml, 2794 +/- 1024 ng/ml, 6300 +/- 2450 pg/ml and 46.6 +/- 4.4 respectively, as compared with 234 +/- 91 ng/ml, 254 +/- 105 ng/ml, 1850 +/- 1100 pg/ml and 36.8 +/- 4.6 in group B respectively. The differences between groups were highly significant for all parameters. Angiogenin seems to be strongly associated with the formation of neovascularization responsible for the development of OHSS.

Moderate ovarian hyperstimulation syndrome complicated by deep cerebrovascular thrombosis.

This report describes two cases that developed moderate ovarian hyperstimulation syndrome (OHSS) without evidence of haemoconcentration. Both patients developed serious cerebrovascular thrombosis resulting in hemiparesis, and recovered after treatment with anticoagulants. This report emphasizes that other factors may contribute to vascular thrombosis, and illustrates that cerebrovascular accidents may complicate even moderate OHSS.

Complications of medically assisted conception in 3,500 cycles.

OBJECTIVE: To investigate the incidence of complications in the use of assisted reproductive technology in the management of infertile couples. DESIGN: Retrospective study. SETTING: The Egyptian IVF & ET Center, Maadi, Cairo, Egypt. PATIENT(S): Two thousand nine hundred twenty-four patients underwent IVF-ET or intracytoplasmic sperm injection (ICSI) in 3,500 cycles. INTERVENTION(S): IVF-ET, ICSI, ejaculate sperm, epididymal sperm aspiration, and testicular sperm extraction. MAIN OUTCOME MEASURE(S): Complications of the procedure and complications of pregnancy in 702 patients. RESULT(S): Fifteen hundred ovum pickups for IVF-ET and 2,000 ovum pickups for ICSI were performed. Clinical pregnancy occurred in 1,078 patients (30.8%). Four groups of complications were identified. Complications of the procedure occurred in 291 patients (8.3%). Complications of pregnancy included ectopic pregnancy in 1.9%, heterotopic pregnancy in 0.2%. abortion in 20.6%, multiple pregnancy in 28%, pregnancy-induced hypertension in 10%, preterm labor in 21.5%, low birth weight in 30.5%, and intrauterine death in 2%. Coincidental complications occurred in five patients (0.15%). Other complications that were difficult to measure included psychological breakdown and socioeconomic problems. CONCLUSION(S): Assisted reproductive technology is effective for the management of infertility and has an acceptable incidence of complications. Complications rarely endanger the life of the patient. When this line of treatment is offered, the indications should be definitive. Patients should be monitored properly and measures should be taken to minimize the incidence of complications.

Is endometrial ablation a safe contraceptive method? Pregnancy following endometrial ablation.

A case of pregnancy following thermal endometrial ablation is presented in this report.
