FULL STORY
Researchers from the Medical Research
Council's Human Reproductive Sciences Unit at The University of
Edinburgh have found that that the high concentration of prostaglandin
in semen makes other diseases of the female reproductive organs worse --
including uterine cancer.
The team, led by Dr Henry Jabbour, an Honorary Fellow in Obstetrics
and Gynaecology at the University, has found the prostaglandins present
in semen can influence the progression of cervical and uterine cancers
by enhancing tumour growth.
Prostaglandin is naturally produced by the cells that line the female reproductive organs. Its usual role is to help regulate cell growth. For example, messages passed on from cell to cell by prostaglandin molecules direct the womb lining to either thicken or shed in the monthly menstrual cycle.
However, the concentration of prostaglandin in seminal fluid is 1000 times higher than that normally found in these cells.
Prostaglandin receptor molecules are present on the surface of the cells that make up cervical and uterine cancer tumours. The influx of prostaglandin delivered by semen enhances the normal level of signalling between cells. The high volume starts new cascades of signals that eventually lead to an increase in tumour growth.
Cervical cancer is most common in women who live in the developing world. In the UK, screening programmes detect most abnormal cell changes in women before a tumour develops. Although prostaglandins do not cause cervical cancer (it is usually triggered by long--term human papilloma virus infection), this research shows that seminal fluid can contribute to tumour growth.
Dr Henry Jabbour said:
"Sexually active women who are at risk of cervical or uterine cancer should encourage their partners to wear a condom to prevent increased exposure to the prostaglandins that might make their condition worse.
"It also highlights the potential for a new therapeutic approach that will tackle both possible sources of prostaglandin, those produced naturally by women and those introduced to the body by sperm."
