13. How the magnitude of clinical severity and recurrence risk affects reproductive decisions in adult males with different forms of progressive muscular dystrophy.
The reproductive history of 177 male patients affected with Becker (BMD) (n=69), limb-girdle (LGMD) (n=54), and facioscapulohumeral (FSHMD) (n=54) muscular dystrophy (MD) was analysed according to severity of the disease (BMD>LGMD>FSHMD) and magnitude of recurrence risk (RR) (high for FSHMD, intermediate for BMD, and low for LGMD). Additionally, 62 male pati

14. Risk-sensitive mating decisions in a visually compromised environment
Reproductive activities are often conspicuous and can increase the risk of predation. Evidence suggests that individuals are capable of responding to predators in a risk-sensitive manner. However, most studies tend to consider only the predator-mediated responses of males and females in isolation and with little regard to differences in local environmental c

15. Neurofibromatosis type 1 (NF1): knowledge, experience, and reproductive decisions of affected patients and families.
Eighty-one subjects (56 affected patients and 25 parents of isolated affected cases) from 63 families with neurofibromatosis type 1 (NF1) on the North Western Regional Genetic Family Register (NWRGFR) were interviewed. Patients were interviewed either before (n = 26) or after (n = 55) genetic counselling. In the group as a whole, knowledge of the clinical fe

16. Ethical reflection on the harm in reproductive decision‐making
Advances in reproductive technologies continue to present ethical problems concerning their implementation and use. These advances have preoccupied bioethicists in their bid to gauge our moral responsibilities and obligations when making reproductive decisions. The aim of this discussion is to highlight the importance of a sensibility to differences in moral

17. Hybridization rapidly reduces fitness of a native trout in the wild
Human-mediated hybridization is a leading cause of biodiversity loss worldwide. How hybridization affects fitness and what level of hybridization is permissible pose difficult conservation questions with little empirical information to guide policy and management decisions. This is particularly true for salmonids, where widespread introgression among non-nat

18. The costs of egg production and incubation in great tits (Parus major).
The costs of egg production and incubation may have a crucial effect on avian reproductive decisions, such as clutch size and the timing of reproduction. We carried out a brood-size enlargement experiment on the great tit (Parus major), in which the birds had to lay and incubate extra eggs (full costs), only incubate extra eggs (free eggs) or did not pay any

19. Should access to fertility-related services be conditional on body mass index?
Guidelines for the clinical management of obese, reproductive age women with reduced fertility in the USA are limited. Clinical professional organizations have yet to publish practice guidelines on this topic. Thus, treatment decisions are made at the provider and/or clinic level and the variation in clinic policy regarding fertility treatment for obese wome

20. Is human existence worth its consequent harm?
Benatar argues that it is better never to have been born because of the harms always associated with human existence. Non‐existence entails no harm, along with no experience of the absence of any benefits that existence might offer. Therefore, he maintains that procreation is morally irresponsible, along with the use of reproductive technology to have chil

21. Ethical considerations in prenatal diagnosis.
Prenatal diagnostic testing raises a number of important ethical issues, some related to diagnostic testing in general and others related to the special circumstances of pregnancy. These issues are most effectively addressed in the context of a broader understanding of the goals of prenatal diagnosis. Our dual obligations--to the pregnant woman and to the fe

22. Knowledge, views, and experience of 25 women with myotonic dystrophy.
Twenty-five affected women of reproductive age known to the North West Regional Genetics Family Register (NWRGFR) were interviewed. A semistructured questionnaire, completed by the interviewer, was used to assess understanding and experience of the clinical and genetic aspects of myotonic dystrophy (MD) and attitudes to prenatal diagnosis (PND). Characterist

23. Strength determines coalitional strategies in humans
Coalitions enhance survival and reproductive success in many social species, yet they generate contradictory impulses. Whereas a coalition increases the probability of successfully obtaining rewards for its members, it typically requires a division of rewards among members, thereby diminishing individual benefits. Non-human primate data indicate that coaliti

24. The primordial pool of follicles and nest breakdown in mammalian ovaries
The creation of the pool of follicles available for selection and ovulation is a multi-faceted, tightly regulated process that spans the period from embryonic development through to the first reproductive cycle of the organism. In mice, this development can occur in mere weeks, but in humans, it is sustained for years. Embryonic germ cell development involve
