The Human Fertilisation and Embryology Act 1990 established the legal framework that governs infertility [3] treatment, medical services ancillary to infertility [3] treatment such as embryo storage, and all human embryological research performed in the UK. The law also defines a legal concept of the parent of a child conceived with assisted reproductive technologies. Section Five of the Act es...

In mammals, the maternal and the paternal genome are not functionally equivalent and are both required for embryonic and postnatal development. The genome is organised differently in the oocyte as compared to sperm, in which the DNA is tightly packaged with protamines rather than with histones. The requirement of both the parental genomes for normal development is a consequence of differential ...

Oxytetracycline (OXY) is a broad-range antimicrobial routinely used in pig production, at doses in the range of few g/kg of medicated feed, during the weaning period. It could persist at ppm level in pig liquid manure that routinely is used for organic fertilisation. In the present work we describe a methodology to study OXY environmental fate in arable land where crops are cultivated for anima...

Oxidative stress contributes to defective spermatogenesis leading to male factor infertility. The aim of this study was to review the current literature on the effects of various antioxidants to improve fertilisation and pregnancy rates. The sources of literature were Pubmed and the Cochrane data base. Reviewing the current literature revealed that Carnitines and vitamin C and E have been clear...

This is the first study analysing individual differences in shyness–boldness and behavioural asymmetries in young zebrafish larvae (fry, 7 days post-fertilisation). Individual differences were more stable in tests with predator model (crude image of a fish face) than with an arbitrary novel stimulus (vertical black stripe). Principal component analysis revealed a dimension of ‘shyness’ that inv...

Cameron and Williamson have provided a provocative and timely review of the ethical questions prompted by the birth of Dolly. The question Cameron and Williamson seek to address is "In the world of Dolly, when does a human embryo acquire respect?". Their initial discussion sets the scene by providing a valuable overview of attitudes towards the embryo, summarising various religious, scientific,...

The debate about the moral status of the embryo has gained new impetus because of the advances in reproductive technology that have made early human embryo experimentation a possibility, and because of the public concern that this arouses. Several philosophical arguments claiming that fertilisation is the event that accords moral status to the embryo were initially formulated in the context of ...
