Despite a high rate of condom use, the Japanese population lacks knowledge and awareness on the use of contraceptives in the prevention of sexually transmitted infections, according to the head of an expert international advisory panel on sexual and reproductive health.

"While many other countries in the world, both developed and developing, are trying to promote condom use for prevention of STIs and HIV, you (Japan) have this high rate of condom use, but it would appear that it is primarily for contraceptive reasons," said Helen Randera-Rees, cochair of the International Medical Advisory Panel.

Randera-Rees made the remarks at a news conference -- joined by five others of the 11-member IMAP -- held at a Tokyo hotel to mark the conclusion late last week of a three-day meeting of IMAP under the International Planned Parenthood Federation.
