Material Development for Condom
Ancient
Rubber : 1855
Latex : 1920
Polyurethane : 1994
Polyisoprene : 2008
Female Condom with nitrile
Rubber Condoms
•Charles Goodyear(1800-1860), American inventor
: discovered a way of processing natural rubber(1839)
- sulfur and natural rubber to be more malleable and durable
: 1st rubber condom(1855)
- large scale production with cheaper price
- reusable/not to fit
•Skin condom from intestine or bladder, more comfortable on the end of 19th C
: required to fit

The Comstock Law of USA, 1873
A federal act passed by the United States Congress on Mar. 3, 1873,
as the Act for the "Suppression of Trade in, and Circulation of,
Obscene Literature and Articles of Immoral Use". The Act
criminalized usage of the U.S. Postal Service to send any of the
following items: erotica, contraceptives, abortifacients, sex toys.
•prohibited the vending of condoms via post
•prevented the public advertising of contraception
:chance to growing the concern about VD

•US Federal Council of Church (1931)
•Roman Catholic

Military Perspective of Condom
•German, promote condom use on later 18th C
•American, provide condom on early 19th C
;chance to growing the concern about venereal diseases
after 1865 on the end of the American Civil War,
The Latex era of Contemporary Condom
Latex(1920’): rubber suspended in water

Prerequisite for Ideal Condom
•water-proof, elastic, durable
•easy applicable
•thin thickness to preserve or enhance pleasure
& to transmit body heat
•fewer adverse effect
•commercially available with good color, odor, transformed shape,
noctilucence, biodegradable
Medical to Industrial Use of Condom
1. Birth control, most popular contraception method
2. STD protection
3. Urine drainage as catheter
4. Semen collector for semen analysis & IUI
5. To reduce the level of antisperm antibody
6. Endo-vaginal or rectal ultrasound probes
7. Fellatio
8. Anti-rape condom to cause pain to attackers
9. To smuggle alcohol, cocaine, heroin
10. To waterproof microphones for underwater recording
11. To protect samples from environment
12. To storage corrosive materials
13. Garrot

World wide Condom Production
•26.3 million(3000 per hour) on 1920’s
•18.6 billion on 2015
World’s largest condom
Guilin, China 2003
Material Characteristics for Condom
•Latex(1920’); conventional
not applicable oil lubricant
•Polyurethane(1994); better transmitting body heat
less allergic
no odor
less elastic
•Polyisoprene(2008); synthetic version of natural latex
better transmitting body heat
not applicable oil lubricant
11
Technical Thickness of Condom
• Usually 0.04 – 0.07 mm thickness
Japan, the highest rate of condom usage in the world in 2008
Estimated Size of Condom in Each Country
Each condom can
hold up to 34 litres
of fluid

Transformed Shape of Condom
: ribbed or studded condom to stimulate G-spot or frenulum

•Breakage rate 0.4-2.3%
Slippage rate 0.6-1.3%
Positive rate of semen residue 1-3%
Pregnancy rate, 2% on perfect use
18% on typical use
•Allergy to latex
Future & Research of Condom
•Invisible condom(2005), developed at Université Laval in
Québec, Canada, is a gel that hardens upon increased
temperature after insertion into the vagina or rectum
•Spray-on condom(2009), easier to apply and more successful
in preventing the transmission of diseases but not going to
market because the drying time
•Dual purpose condom with transformation, medication
: to reduce slippage
to enhance penile size
to be medicated for ED/PE
to be with spermicide for greater protection, nonoxynol-9

Conclusion
Condom research would be evolved to
creative territory in aspect of not only
use objective, production material,
consumer compliance, but also
business on coming future.
