Women who are younger than 38 years old are more likely to experience success following intracytoplasmic sperm injection (ICSI) treatment, new research has revealed.
Females who are less than this age when they undergo treatment and who have 11 or more eggs which have been retrieved from their ovaries in one ovarian stimulation cycle have more chance of giving birth to a live baby, a Belgian study has shown.
Data from a total of 23,354 ovarian stimulation cycles carried out at UZ Brussel were used for the study, which looked at women who had undergone ICSI between 1992 and 2009.
The live birth rate was dependent upon ovarian response, the researchers found.
Those who had six to ten eggs retrieved were 4.3 per cent less likely to have a live birth than the women who had 11 or more eggs.
Eleonora Jansen, an obstetrics and gynaecology resident in training at the Centre for Reproductive Medicine, Belgium, said the results of the study will enable fertility experts to "calculate the chances of a pre-clinical abortion, a miscarriage or a live birth".
A recent study by Yale University School of Medicine, US, revealed that mothers who are obese affect the fertility of their offspring, because they have lower levels of the hormone ghrelin, which leads to their children being less fertile. Read More
