Wellington, Sep 05, 2017: Having a baby may never be the same again as increasingly sophisticated genetic testing is likely to raise thorny ethical issues, a New Zealand study said on Tuesday.

“Pregnant women now face a bewildering world of genetic testing,” said Jeanne Snelling, the lead author of the New Zealand Law Foundation Report.

Genetic testing in the reproductive context is a particularly high-stakes endeavour, Snelling said, adding that it directly affects a woman’s experience of pregnancy, and may contribute to a decision not to transfer an embryo or to terminate an established pregnancy, reports Xinhua news agency.

The study looks at a number of rapidly evolving genetic technologies that a woman may be offered, either during pregnancy or regarding embryos created by IVF (in-vitro fertilization).

A common feature of all of these tests is that they enable an increasing and significant amount of health-related information to be derived, compared with traditional prenatal tests, and all are associated with particular technical, ethical and legal challenges, Snelling said.

“The report considers how this new landscape reignites debates about the implications of new technology for women and how it affects the experience of pregnancy.” (IANS)

Women who consume paracetamol during pregnancy, widely used to reduce a high fever or relieve pain, may increase the risk of damaging the fertility of their daughters, warns a new study.

“This study identifies a potential risk from taking parace0tamol or ibuprofen, although we don’t know exactly what effect it would have on human health nor what dose would be needed to harm fertility,” said Richard Sharpe, professor at the varsity.

  • Human ovaries exposed to paracetamol for a week in laboratories lost up to 40 per cent of their egg cells.
  • If this effect occurs in the womb, it could mean baby girls exposed to the common drug end up being born with fewer eggs.
  • This would give them fewer years in which they could become pregnant and lead to an early menopause.
  • It may be because both paracetamol and ibuprofen interferes with a hormone called prostaglandin E2, which appears to play a vital part in the development of the foetal reproductive system.

Methodology

  • The team tested the effect of paracetamol and ibuprofen on human foetal testes and ovaries over a week. Researchers counted germ cells that turn into sperm and eggs.
  • In the ovary, the number of egg cells fell by up to 40 per cent, while in testes the number of germ cells was reduced by more than a fifth.

While unborn boys could also be affected by the drug. But unlike women, whose egg supply is limited, they keep producing sperm throughout their lives, meaning the danger to their fertility is not as serious, the researchers said.
