Epidemiological studies based on the immune theory showed the relationship between exposition to sperm and preeclampsia. Repeated exposition to seminal liquid would therefore be a protection against preeclampsia, as observed in women having frequent unprotected sex, or having had a previous normal pregnancy with the same partner. Other publications showed an increased risk of preeclampsia in patients who received sperm during an intrauterine insemination (IUI) or during an in vitro fertilization (IVF). We report a case of reoccurrence of severe preeclampsia in a mixed afro-caucasian couple having had a child delivered normally at term in the past. The couple later went for a sperm donation as a result of a chemotherapeutic treatment for Hodgkin Lymphoma which the man suffered from. The fact that the sperm was gotten from the same donor did not stop the reoccurrence. The first pregnancy gotten from sperm donation ended up into a medical termination of pregnancy (MTP) at 23 weeks 2 days of amenorrhea, and the second pregnancy issued from the same donor ended into a cesarean delivery at 28 weeks of a child with intrauterine growth retardation (IUGR).展开更多

Results highlight that donors desire to act responsibly with recruiting facilities is not always possible. Objective: Obtaining the views and experiences of sperm donors regarding health and genetic matters. Design: Online survey. Setting: Not applicable. Participants: 164 previous sperm donors. Interventions: Not applicable. Main outcome measures: Views and experiences on health and genetic issues. Results: A variety of approaches are adopted by recruiting facilities in regard to selection and post-donation factors. The vast majority of donors said they had not been contacted by the facility they donated at to update their medical information, while almost one quarter of donors indicated that a health or genetic risk factor had occurred. A great majority of donors felt that they had not received any education or counselling on the potential curiosities of donor conceived people. Donors sought to be honest and open with staff but often found there were difficulties in doing so. Conclusions: Overall, donors indicate that they see donating as involving responsibilities to the offspring and families. The study highlights however that their ability to act responsibly is limited by some of the interactions or lack of them with the facilities where they donated. Implications for recruiting facilities need to be considered.展开更多

This research presents the current status of sperm donation in China's Mainland and highlights some problems. Between January 2003 and December 2009, 19 471 sperm donors were screened totally and 6467 donors （33.2%） were recruited. The primary reasons for non-recruitment were either inadequate semen parameters （55.0%） or positive results for sexually transmitted diseases （7.9%）. There were 327 （1.7%） qualified donors who withdrew from the program because of frustration related to failed semen parameters, participation merely for free medical tests or job transfer. A questionnaire investigating donor intention, as well as other concerns associated with sperm donation, was distributed to 516 potential donors. All potential donors indicated their primary motivation as altruism, while 90.9% mentioned monetary reward as a second motivating factor. Approximately 93.4% of donors expressed some apprehension about the risk of consanguineous mating and the protection of their identity. Over the past 7 years, 488 389 vials of donors＇ semen have been cryopreserved. In 36 438 artificial insemination with donor sperm （AID） cycles, the clinical pregnancy rate was 23.9% and the live birth rate was 16.6%, In 7148 in vitro fertilization cycles, the clinical pregnancy rate was 45.8% and the live birth rate was 35.2%. Human sperm banks have been strictly monitored to ensure that each sperm donor can only impregnate five women nationwide. There is still a large gap between the supply and demand for sperm donation which may be solved by updated guidelines.展开更多

Ethical issues concerning sperm donation have been considered and discussed by government and non-governmental agencies, the public, media and academic institutions in many countries. Recommendations and guidelines concerning sperm donation issues vary from country to country and between professional groups within countries. This paper attempts to present an overview of findings and reports from various agencies concerning the ethics of sperm donation. The following topics are considered： limiting the number of donor offspring; minimizing risk of infection and genetics from sperm donors; age requirements for sperm donors; and anonymity versus non-anonymity of sperm donors. The diversity of policies shows that each country has its unique set of guidelines tailored toward its own specific needs. Similarly, countries designing their own procedures and guidelines concerning reproductive medicine must tailor them toward their own needs and practical considerations. In China's Mainland, the anonymous policy for sperm donation should still be carried out, and the number of donor offspring should be revaluated. ART procedures must be conducted in a way that is respectful of those involved. Ethical principles must respect the interests and welfare of persons who will be born as well as the health and psychosocial welfare of all participants, including sperm donors.展开更多
