New York, July 18, 2017: Love to speak to your unborn baby? Well he or she can typically distinguish the difference between sounds used in various languages even a month before being born, an interesting study has shown.

The study showed that foetuses can hear things, including speech, in the womb, although the voice is muffled.

In the study, the foetal heart rates changed when they heard the unfamiliar, rhythmically distinct language (Japanese) after having heard a passage of English speech, while their heart rates did not change when they were presented with a second passage of English instead of a passage in Japanese.

“The results suggest that language development may indeed start in utero. Foetuses are tuning their ears to the language they are going to acquire even before they are born, based on the speech signals available to them in utero,” said lead author Utako Minai, associate professor from the University of Kansas.

“Pre-natal sensitivity to the rhythmic properties of language may provide children with one of the very first building blocks in acquiring language,” Minai added.

For the study, published in the journal NeuroReport, the team examined 24 women, averaging roughly eight months pregnant.

Minai had a bilingual speaker make two recordings, one each in English and Japanese — argued to be rhythmically distinctive language, to be played in succession to the foetus.

“The intrauterine environment is a noisy place. The foetus is exposed to maternal gut sounds, her heartbeats and voice, as well as external sounds.

“Without exposure to sound, the auditory cortex wouldn’t get enough stimulation to develop properly. This study gives evidence that some of that development is linked to language,” explained Kathleen Gustafson, a research associate professor at the varsity. (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.
