Abstract

Purpose – Using elective egg and sperm freezing as a case to compare representations of men and women as agents of biological reproduction, this chapter aims to understand how gender and risk are co-produced in the context of new reproductive technologies (NRTs).

Methodology – Through a content analysis of newspaper articles published between 1980 and 2016 about egg and sperm freezing, the author traces how fertility risks facing men and women are portrayed in the media.

Findings – Candidates for egg freezing were portrayed in one of the three ways: as cancer patients, career women, or single and waiting for a partner. The ideal users of sperm freezing are depicted in primarily two ways: as cancer patients and as employees in professions with hazardous working conditions. Threats to future fertility for women pursuing careers uninterrupted by pregnancy and child-rearing and women seeking romantic partners are largely portrayed as the result of internal risks. However, threats to future fertility for men working in dangerous professions are largely portrayed as external to them.

Research Limitations – Race and class did not emerge as dominant themes in these data; given the lack of accessibility to NRTs by class and race, this silence must be interrogated by further research.

Value – By comparing the constructions of at-risk groups, the author argues the medicalization of reproduction is gendered as fertility risks portrayed in the media take on a different character between men and women. This research shows how the gendered construction of infertility risk reinforces normative expectations around child-rearing and perpetuates gender inequity in parenting norms.

Abstract

Derek Parfit’s non-identity problem calls into question the claims of both the state and individuals when they purport to act for the benefit of future children. This paper discusses how adoption of the non-identity argument as a legal argument could affect reproductive and family policy, demonstrating that it undermines the child-centric approach to assigning legal parentage. The paper concludes, however, that these non-identity problems can be solved by the expected value approach, which demonstrates that efforts to benefit future people can be logically coherent even if those efforts also affect the genetic identities of the future people.

Abstract

In this chapter I consider the need for consent in two cases of posthumous donation of parts of one’s body: organ donation and the donation of sperm to allow one’s partner to conceive a child after one’s death. What kind of consent is appropriate in these cases and why? In both cases, jurisdictions tend to prefer explicit consent, although many countries now adopt presumed consent (opt-out) in the case of organ donation, and there has been a recent plea for presumed consent in the case of sperm donation as well. In this chapter I first argue that arguments in favour of presumed consent are inadequate as they stand, and then describe another way of understanding opt-out schemes, one that focuses on different models of what is at stake and on the ethical requirements incurred on such models.

Abstract

Purpose

This paper aims to design to evaluate the protective effect of vitamin E to ameliorate the disturbances in testosterone pathway and sperm quality of male rats induced by the glycosides vicine (V) and convicine (C) of Vicia faba.

Design/methodology/approach

Forty male albino rats were divided into five equal groups; control, paraffin oil, V (400 mg/kg) C (150 mg/kg)-treated group, vitamin E (100 mg/kg) + VC-treated group, and vitamin E (200 mg/kg) + VC-treated groups which injected intraperioneally (IP) with 0.5-ml saline, 0.5-ml paraffin oil,V (400 mg/kg) and C (150 mg/kg) of Vicia faba, vitamin E (100 mg/kg) + VC-treated groups, and Vitamin E(200 mg/kg) + VC-treated groups, respectively. Blood and testicular tissue were obtained after one month of the study. The male genital organs were calculated. Testosterone (Ts), luteinizing hormone (LH), follicle stimulating hormone (FSH), dehydroepiandrosterone sulfate (DHEA-SO4), sex hormone binding globulin (SHBG),?-glutamyl transpeptidase (?-GT), glucose-6-phosphate dehydrogenase (G6PD), 3ß-hydroxysteroid dehydrogenase (3ßHSD), lactate dehydrogenase (LDH), spermatozoa concentration, percent of mortality and abnormal sperms were evaluated.

Findings

The VC-treated group showed significant decrease (p < 0.01) in Ts, DHEA-SO4, G6PD, spermatozoa number and mortality percent, as well as, the male genital organs (testes, epidydemis, seminal vesicle, prostate and vasa deferentia) while significant increase (p < 0.01) was found in LH, FSH, SHBG, LDH, ?-GT, sperms monoclonal Ki-67, and abnormal spermatocytes levels compared with control group. Vitamin E co-injection with VC-treated group returned all these parameters to the normal values. The higher dose of vitamin E (200 mg/kg) was more effect than the lower dose (100 mg/kg).

Originality/value

Vicia faba contains V and C glycosides. The V and C glycosides in Vicia faba are hydrolyzed by intestinal microflora to aglycones divicine and isouramil, respectively. Divicine and isouramil are highly reactive compounds generating free radicals where divicine and isouramil are the main factors of favism. The V and C glycosides induced disturbances in testosterone pathway and sperm quality of male rats and vitamin E ameliorates these disturbances.

Abstract

Donor-conceived (DC) offspring raised in lesbian-parent and heterosexual-parent families have different historical chronologies, which are clusters of events that provide frameworks for shaping contemporary views of sperm donors and donor siblings. Using surveys collected by the Donor Sibling Registry (DSR), the largest U.S. web-based registry, we found that DC offspring from different family forms have somewhat different views about meeting both the donor and donor siblings. In general, all offspring are curious about the donor. All offspring want to know what the donor looks like and they believe that even minimal contact will help them understand themselves better. However, when compared to offspring from heterosexual-parent families, offspring from lesbian-parent families are less likely to want to have contact with the donor. For offspring from lesbian-parent families, donor conception is considered a normal and accepted part of family life and the donor is deemed irrelevant to the family’s construction. Especially among those who live with two heterosexual parents (where both parents are often assumed to be genetic relatives), offspring want to know the donor because they believe he holds the key to important information that the legal (or social) father cannot provide. Most DC offspring want to meet donor siblings although the interest is somewhat weaker among the offspring in lesbian-parent families. Offspring regard donor siblings as special relations who will not disrupt the natal family and who might even become part of a new kind of “extended family” network.
