Kate Hill: Australian Woman Becomes Pregnant Twice in 10 Days

Kate Hill from Australian has given birth to twins conceived ten days apart.

She was told she might never become pregnant before receiving hormone treatment for polycystic ovary syndrome, a condition that meant she was not ovulating.

Kate Hill apparently conceived twins at different times despite only having unprotected intercourse once during that time.

It is very rare for a woman to conceive a second time when already pregnant.

Most twins are the result of a woman releasing two eggs at the same time, or, less commonly, a fertilized egg subsequently splitting into two.

According to reports, the twin girls, Charlotte and Olivia, were born 10 months ago with different sizes, weights and gestational development.

Kate Hill told Australia’s Seven Network: “We actually did not realize how special that was until they were born.”

Pregnancy normally stops the monthly cycle of ovulation but very rarely a woman can release another egg after conceiving. If this is fertilized it could also implant and develop into a healthy pregnancy.

It is believed only 10 cases of the phenomenon, known as superfetation, have been documented across the world.

Speaking about the rare conception, Kate Hill’s husband Peter joked: “Hole in one, maybe.”


The couple’s obstetrician Brad Armstrong said the condition was so rare he was forced to search for it online.

“I could not find any literature in the medical review websites at all,” he said.
