Question: Pregnancy after sterilisation
Q: “After having three caesareans, I was advised to be sterilised and I agreed to this. But a year and a half later, I think I could be pregnant again. I just want to know if this is possible even though I am still having monthly periods. I have put on some weight, but I also…

Fertility option – ICSI and SUZI
A relatively new technique called intracytoplasmic sperm injection (ICSI) allows a single sperm to be injected directly into the centre of the egg. An alternative is sub-zonal insemination (SUZI), where a single sperm is placed just beneath the zona pellucida (the protein shell which surrounds the egg). ICSI and SUZI can be of great benefit to couples where…

Decision imminent on frozen eggs
A DECISION is expected today on whether the current ban on fertilising a woman’s frozen eggs will be lifted. The Human Fertilisation and Embryology Authority is expected to announce its findings today, but there is no indication which way they will go. Current rules mean that a woman’s eggs can be frozen, but at…
Sex selection on the way
28 June 1999 A new way of selecting the sex of animals has been developed, and it could be applied to humans in the future. Three female calves were born last month after the father’s sperm was successfully sorted into male and female sperm. The same technique could be used with human sperm, which opens up a…

Glowing Sperm Could Aid Fertility Research
A technique to make sperm glow green could aid research into infertility, say scientists. A team from Oxford University have used a gene from jellyfish that makes a green protein and used it to create green sperm in hamsters. Hamster sperm is very similar to human sperm so researchers can study it to discover why…
Hope for infertile women
Childless couples affected by the woman’s infertility could still have a child that is genetically theirs, using a donor egg, researchers have claimed. The new technique, which has not yet reached the stage of producing a baby, allows doctors to change the genes of the donated egg by ‘gluing’ on the genes of the mother-to-be.…

Fertility gene discovered
28th October 2005 Scientists have found the gene responsible for controlling a first key step in the creation of new life. Researchers from the UK and France believe the HIRA gene is involved in the events necessary for the fertilisation that take place once a sperm enters an egg. The scientists say that a fault in…

Avoiding Soya May Help Fertility
Women should avoid eating soya products around their fertile time of the month if they are trying for a baby, according to a fertility expert. Professor Lynn Fraser, from King’s College London, has told a European fertility conference that a compound in soya called genistein sabotages the sperm as it swims towards the egg. She…
Sperm race into Millennium Dome
6 December 1999 PREGNANT? Not quite sure how it happened? Don’t worry – the Millennium Dome is here to explain it all. The latest attraction unveiled by the organisers of the Dome, which stands on the banks of the Thames in London, is an animated film of a sperm’s race to fertilise an egg. And, although…
