Answer to Question #164018 in Biology for EUGINE HAWEZA

Question #164018

write a full report on the effectiveness of barrier methods, surgical methods, chemical methods, and behavior methods on the control of pregnancies and sexual transmissible diseases.  

Expert's answer

Barrier methods. Out of 100 women per year, 18–28 women will become pregnant when using barrier methods. However, both male and female barrier techniques are 98% efficient for pregnancy prevention. However, female barriers are almost not efficient against sexually transmitted diseases while male condoms are highly effective at disease protection.

Surgical methods. These approaches are 99% effective at preventing pregnancy but do not protect from infectious diseases.

Chemical methods. The methods have lower efficiency (90-95 %) at preventing pregnancy but do not prevent the transmission of diseases.

Behavior method. Sexual abstinence does no have hormonal side effects. This method is 100% effective in preventing pregnancy, and it also avoids sexually transmitted diseases. However, for coitus interrupts, the failure rate approaches 20% and does not protect from diseases.
