FDA Approval Process Lifestyle Issues Choosing a Method of Contraception
FDA Approval Process • The U.S. Food and Drug Administration (FDA) must formally approve the method • 10-14 year process to develop a new contraceptive drug • Drug company submits a new drug application demonstrating safety in animal tests & a desire to conduct human trials
FDA Approval Process • 3 phases • Phase 1: 20-80 volunteers to test effectiveness • Phase 2: several hundred to test effectiveness, side effects, risks • Phase 3: hundreds to thousands are tested for generalization • Animal trials are conducted throughout the process
Class Discussion: Lifestyle Issues Associated with Contraceptive • The following factors seem to be associated with choosing a contraceptive method: • Own health & risks • Number of sexual partners • Frequency of intercourse • Risk of acquiring a STI • Responsibility level • Method cost • Advantages & disadvantages of the method • Discuss influence of each.
Barrier Methods: Condoms and Caps • Prevent sperm from entering the uterus • Barrier Methods: • Condoms • The Diaphragm • The Contraceptive Sponge • The Cervical Barriers
Condoms • 1850 – latex condoms available in the U.S. • $10-$15/dozen • Non-expired condom is rolled onto an erect penis (foreskin pulled back), ½-inch empty space at the tip • Water-based lubricants for latex condoms • Condom grasped at base when withdrawing • Latex condoms have lower rates of slippage & breakage, and offer better STI protection
Condoms • In 1994, female polyurethane/nonlatex condoms were available • $2 each • 7 inches long with 2 flexible rings • Inner ring squeezed and inserted close to the cervix • Outer ring lies outside the vagina • Adequate lubrication is necessary
Condoms • Effectiveness rates • Latex condoms: 85-98% • Female condoms: 79-95% • Latex & polyurethane protect against STI transmission • Lambskin condoms block sperm, but contain holes large enough for viruses to pass through • Heat can damage condoms
Condoms • Advantages: • STI protection • Encourages male participation • Inexpensive • No prescription necessary • Can reduce premature ejaculation • Can reduce postcoital drip • No medical side effects
Condoms • Disadvantages: • Reduces spontaneity • Can reduce sensation • Female condoms can be difficult to use, uncomfortable, noisy • Female & male condoms should never be used together • Popular in some countries, not used in others
The Diaphragm • Not widely used, almost 0% in 2002 • Made of latex or silicone • Many sizes and shapes; a fitting by a health care provider is necessary • $20-$35 diaphragm, $13 spermicidal jelly/cream, office visit charge • They can last for many years
Diaphragms come in a variety of different shapes and sizes and must be fitted by a health-care provider.
The Diaphragm • Diaphragm rim is covered in spermicidal jelly & a tablespoon of jelly is placed in the dome; it is folded in half and inserted into the vagina with the front rim tucked under the pubic bone • It should not be felt & should cover the cervix • It can be inserted up to 6 hours prior to intercourse • Left in for at least 6-8 hours, no more than 24 • After use it is washed with soap & water
The Diaphragm • 84-94% effective, lower for those who have given birth • Advantages: • Increases spontaneity • Some STI & PID protection • Reduces risk of cervical dysplasia & cancer • Does not affect hormonal levels • Relatively inexpensive
The Diaphragm • Disadvantages: • Physician fitting and prescription • Insertion & removal involves touching the genitals • Increased risk of toxic shock syndrome and urinary tract infection • Postcoital drip • Low usage outside the U.S.
The Contraceptive Sponge • The Today contraceptive sponge was taken off the market for a decade due to issues with the manufacturing plant; reintroduced in 2005 • Available over the counter in one size • The sponge covers the cervix & contains spermicide; it blocks, absorbs, & deactivates sperm • One box of 3 sponges is $13
The Today contraceptive sponge was back on the market in late 2005 in the United States.
The Diaphragm • Sponge is moistened with water to activate the spermicide, folded in half, & inserted to cover the cervix • Can be inserted up to 24 hours in advance, with intercourse occurring as many times as desirable in that time period • Must be left in at least 6 hours after intercourse • 75-89% effectiveness rates
Instructions for proper insertion of a contraceptive sponge.
The Diaphragm • Advantages: • No prescription necessary • Can have intercourse several times within 24 hours • Increase sexual spontaneity • Do not affect hormonal levels • Disposable
The Diaphragm • Disadvantages: • Increased risk of toxic shock syndrome & urinary tract infection • Cannot be used while menstruating • Requires touching of the genitals • High expense if frequently used • Some men can feel it • Low usage rates in other cultures
The Cervical Barriers • Thimble-shaped, silicone barriers that fit over the cervix • Block entrance to the uterus & deactivate sperm with the spermicide • Fitting by a health care provider is necessary • Two types: • FemCap • Lea’s Shield
The FemCap is a silicone cup shaped like a sailor’s hat that fits securely over the cervix.
Lea’s Shield is a silicone cup with a one-way valve and a loop for easier removal.
The Cervical Barriers • $15-75 plus cost of spermicide • Left in place for 8 hours after intercourse • After use, it is washed with soap & water • Not to be used during menstruation • 86% effectiveness rate, lower for those who have had children
The Cervical Barriers • Advantages: • Left in place for up to 48 hours • Do not affect hormonal levels • Immediately effective • Not permanent • One-way release valve in Lea’s Shield reduces risk of toxic shock syndrome
The Cervical Barriers • Disadvantages: • Abnormal Pap smears • Increased risk of urinary tract infections • Increased vaginal odors • Cervical damage • Increased postcoital drip • Fitting is necessary • Some male partners feel it & may dislodge it
The Cervical Barriers • Widely used in England • Lea’s Shield is available over the counter in Germany, Austria, Switzerland, & Canada
