Answer to Question #164018 in Biology for EUGINE HAWEZA

Question

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.  

Answer 1

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.
