Temporary methods:

These are of following types :

1. Natural method/ Safe period / Rhythm

method :

In the natural method, the principle

of avoiding chances of fertilization is used.

A week before and a week after menstrual

bleeding is considered the safe period for sexual

intercourse. This idea is based on the fact that

ovulation occurs on the 14th day of menstrual

cycle. Its drawback lies in having a high rate

of failure.

2. Coitus Interruptus or withdrawal :

In this

method, the male partner withdraws his penis

from the vagina just before ejaculation, so as to

avoid insemination. This method also has some

drawbacks, as the pre-ejaculation fluid may

contain sperms and this can cause fertilization.

3. Lactational amenorrhea (absence of

menstruation) :

This method is based on the fact

that ovulation does not occur during the period

of intense lactation following parturition.

Therefore, as long as the mother breastfeeds the

child fully, chances of conception are almost

negligible. However, this method also has high

chances of failure.

4. Chemical means (spermicides): In this

method, chemicals like foam, tablets, jellies,

and creams are used by the female partner.

Before sexual intercourse, if these chemicals

are introduced into the vagina, they adhere to

the mucous membrane, immobilize and kill the

sperms. It may cause allergic reaction. This

method also has chances of failure.

5. Mechanical means / Barrier methods:

In this method, with the help of barriers the

ovum and sperm are prevented from physically

meeting. These mechanical barriers are of three

types.

i) Condom: It is a thin rubber sheath that

is used to cover the penis of the male

during coputation. It prevents the entry

of ejaculated semen into the female

reproductive tract. This can prevent

conception. It is a simple and effective

method and has no side effects. “Nirodh”

is the most widely used contraceptive by

males. It is easily available and is given free

by the government. It should be properly

discarded after every use. Condom is also

a safeguard against STDs and AIDS.

ii) Diaphragm, cervical caps and vaults:

These devices used by the female are made

up of rubber. They prevent conception

by blocking the entry of sperms through

the cervix. The device is inserted into the

fem

Temporary Birth Control

Your options include:

Rhythm method — This involves not using birth control and avoiding sex during fertile times of the month.

Hormonal methods — Includes the pill, vaginal ring or a hormone patch. They mimic natural hormones in a woman’s body. They prevent ovulation and change the uterus and cervix so fertilization is much less likely to happen.

Barrier methods — Condoms, a diaphragm, sponge or cervical cap. The barriers stop sperm from reaching the egg.

Injectable methods — Progestin is injected every three months. Since the hormone dosage is less than other options, some patients prefer it. This method prevents conception similarly to other hormonal methods.

You may prefer a long-acting reversible contraceptive (LARC). These methods can last for three to 10 years. LARCs include:

Intrauterine devices — A T-shaped device is inserted into the uterus. The devices keep sperm from reaching the egg. There are two types of IUDs, hormonal and non-hormonal. Copper, non-hormone containing IUDs last approximately 10 years and hormone containing IUDSs last 3 to 5 years.

Hormonal implants — A match-stick sized plastic rod is implanted under the skin of the patient’s upper arm. The rod releases a special contraceptive hormone. This delivery system has hormonal results similar to hormonal and injectable methods.
