Sexual intercourse

The male barrier contraceptive device is known as the condom, or mbber, and is widely available in most countries. The condom is a mbber or latex sheath, sometimes packaged with a lubricant and spermicide, which serves as a cover for the penis and a receptacle for semen. The method is very effective if the condom is of good quaUty, remains on, and is replaced for each subsequent intercourse. It was reported that 6 biUion condoms were used in 1990 (101). Usage appears to be increasing as adjunctive use with other methods of contraception for prevention of HIV or other sexually transmitted diseases. By rough estimate, condoms may have been used in more than 13 biUion acts of sexual intercourse that risked unwanted pregnancy, HIV, and/or other sexually transmitted diseases (101). 

In order to avoid conception, abstinence from sexual intercourse during the fertile period of the menstmal cycle must be practiced (77,104). It has been deterrnined that the fertile period in women occurs before menstmation (105,106), and formulas have been developed to determine the fertile and infertile days of the menstmal cycle. Ovulation has been linked to a cycHc shift in basal body temperature (107), which can be used retrospectively to determine the time of ovulation.

Erectile dysfunction (ED) is defined as the inability to achieve or maintain an erection sufficient for sexual intercourse. The definition is very subjective due to differences in desired or needed rigidity in patients of different ages and in different types of relationships. Patients may refer to their dysfunction as impotence, but the National Institutes of Health Consensus Development Conference recommends that the term erectile dysfunction replace the term impotence due to confusion with other forms of sexual dysfunction and the negative connotation associated with the term impotence.1 Patients may also develop libido or ejaculatory disorders, but these are not considered erectile dysfunction. 

Several risk factors are known to exist in men and women.
