Contraceptives are generally drugs and devices, which are used to prevent pregnancy. A large number of contraceptives are available which allow the couple to enjoy sex without running the risk of unwanted pregnancies. The general categories of contraceptives are explained below:

Barrier Methods:
i. Male Condom: It is one of the most common forms of contraception. They are worn on the penis before sex is initiated. For safety purpose, a new condom should be used every time the person has sex.

ii. Female Condom: Much like male condoms, these are available at over-the-counter pharmacies without prescription. The condoms can be inserted to the vagina anytime within a period of 8 hours prior to sex.

iii. Diaphragm: This should be coated with a spermicide before sex and placed inside a woman's vagina so that the sperms are prevented from entering the uterus.

iv. Cervical Cap: These are used as replacements for diaphragms because some women may develop bladder infections such as cystitis while using it and these caps have lesser contact with the vagina.

Hormonal Methods:
The main implementation of hormonal changes to provide contraception is the pill. This is the most common form of female contraception available. It comes in two forms:
i. Combined contraceptive pill: Contains a combination of hormones such as progestin and oestrogen.
ii. Mini-pill: Contains only progestin: It is available only with the prescription of the doctor and should be used as per the prescription.

Intrauterine Devices
The intrauterine device (IUD) is a long-acting and reversible form of contraception for women. It is of two types: Copper IUD (contains copper) and Hormone-releasing IUDs (progestin hormone is released into the womb slowly). It is a small device that is fitted inside the womb and it provides contraception by facilitating the prevention of fertilization of the egg.

Sterilization
This is a lifelong option that is available for both men and women. In males, the procedure is known as vasectomy which basically ties and cuts off the tubes that carry the sperm.

In women, two forms of sterilization are available; surgical and non-surgical. Surgically, the fallopian tubes are cut and tied using small cuts in the belly so that the ovaries and uterus are not linked. Non-surgically, coils are inserted into the fallopian tubes so the resultant development of scars leads to complete blockage of the tubes.

Other forms of contraceptives include contraceptive patches, vaginal rings, contraceptive injections, spermicides and contraceptive implants.

Different Types of Contraceptives and Its Uses

Emergency is helpful in preventing pregnancies post unprotected sexual activity. It can be used in case of contraceptive failure, in case of sexual assault, incorrect use of contraceptives and unprotected sex.

Emergency contraception can be done by three methods. These are emergency contraceptive pills, combined oral contraceptive pills and copper intrauterine devices.



The copper IUD is considered to be one of the most effective forms of emergency contraception, when it is inserted within 5 days of unprotected sexual activity.

However, the emergency contraceptive pill regimen as per WHO is:

1 dose of levonorgestrel 1.5 mg, or 1 dose of ulipristal 30 mg, taken within 5 days (120 hours) of unprotected intercourse

The Yuzpe regimen which consists of 2 doses of combined oral contraceptive pills

What is Emergency Contraception?

Emergency contraception is usually referred to as the contraception which is used to prevent a pregnancy within the first 5 days after an unprotected sexual activity. It is used post failures of contraception, coerced unprotected sex, rape or misuse of contraception.

Emergency contraception is only effective in the first few days after an intercourse and before the egg has released from the ovary, and before there is fertilization between the egg and the sperm. The emergency contraception can do no harm to an interrupted pregnancy and a developing embryo.

Who needs emergency contraception?

Any girl or woman who is at her reproductive age might need an emergency contraception in case of an unprotected sexual intercourse.

Uses
1 Breakage , slippage or displacement of barrier methods 
2. Three or more missed OCPills for more than 12 hours 
3. Missed Mini pill for more than 3 hours 
4. Missed Desoestrel pills for more than 12 hours 
5. DMPA injections taken more than 2 weeks late 
6. Miscalculated dates of last period and present ovulation side effects 
These are meant only for emergency contraception and NOT AS A REGULAR CONTRACEPTIVE. It involves pumping of a hormone inside your body at levels which are 5 times higher than normal. hence excessive and unnecessary use may cause irregularity in the period cycles and an adverse effect on the menstrual health over a period of time. Ideally it should be taken under guided medical supervision.


In what situations should emergency contraception be used?

Emergency contraception can be used after a sexual intercourse. These include:

In case of no use of contraceptives

If it is a case of rape or coerced sex, where the woman was not protected

Miscalculating the periods, failure from using a barrier on the fertile days

Expulsion of an intrauterine contraceptive device (IUD)

Methods of Emergency Contraception:

There are three emergency contraception methods:

Copper-bearing intrauterine devices (IUDs)

Emergency contraception pills (ECPs)

Combined oral contraceptive pills or the Yuzpe method



Safety of Emergency Contraception

There are two methods by which abortion can be done:

Medical Abortion - Non-surgical abortion in which medicines are used to induce abortion

Surgical Abortion - Use of transcervical procedures for terminating a pregnancy, including vacuum aspiration, and dilatation and evacuation (D and E).

Surgical or Medical Abortion for Unwanted Pregnancy

If pregnancy is lesser than = 7 weeks; medical method with Mifepristone with Misoprostol is favorable as the success rate is as high as 97%.

If pregnancy is between 7-12 weeks; surgical abortion is the only option.

If pregnancy is beyond 12 weeks - 20 weeks, then the woman needs to be hospitalized and will be given either Mifepristone followed by Misoprostol tablet or only Misoprostol tablets and woman will then abort like a miscarriage in the hospital. If any products are remaining, then it will be evacuated surgically.

Surgical abortion is preferred if patient desires concurrent tubal ligation or IUCD (CuT) insertion.

If a woman fulfills the criteria for selecting either method i.e. before 7 weeks, final choice has to be given to the woman.

Summary of choice between Surgical or Medical abortion in India

lesser than = 7 weeks - Medical method or surgical method

7-12 weeks - Surgical abortion

12 - 20 weeks - Medicines with or without surgical procedure in hospital

Advantages of Medical Abortion

Avoid surgery

Controlled by the woman and may take place at home

No need for admission to the hospital

Usually, well tolerated by women, if properly counselled and motivated

No need to take leave from work, as bleeding can be managed with menstrual pads even while in the office or at work.

Disadvantages of medical abortion

Takes time (hours to days) to complete abortion, and the timing may not be predictable. Women experience bleeding and cramping, and potentially some other side-effects (nausea, vomiting, fever, and shivering). May require more clinic visits than surgical abortion.

Advantages of Surgical Abortion

Quick procedure

Complete abortion easily verified by evaluation of aspirated products of conception

Takes place in a hospital so Sterilization or placement of an intrauterine device (IUD) may be performed at the same time as the procedure. It can be performed under local anaesthesia if woman is properly motivated and counselled

Disadvantages of surgical abortion

Requires instrumentation of the uterus

Small risk of uterine or cervical injury

Timing of abortion controlled by the doctor and hospital

Anaesthesia needs to be administered. Most doctors perform this procedure under short general anaesthesia. A woman needs to be in the hospital for at least 6 hours. Effect of sedation will be there throughout the day.

Methods of Abortion for Unwanted Pregnancy

A birth control pill is commonly referred to as an oral contraceptive pill. A form of hormonal contraception and is a highly effective method of birth control. Only 1% of women experience unintended pregnancy when on the pill.

Birth control pills are of two types i.e combination pills and mini pills. Combination pills contain synthetic forms of the two hormones called oestrogen and progesterone. The mini pill only contains the hormone progesterone and is called progestin.

However, the pill does have some side effects to it. These include the following:

Intermenstrual spotting: Within the first three months of starting the pill, women experience vaginal bleeding between the two period cycles.
Nausea: Although the symptoms subside after some time, some women till experience nausea for a while after taking the pill. If one consumes the pill with food or before going to bed, this can help lower the likelihood of feeling nauseous.
Breast tenderness: The breasts might feel tender and enlarged after taking the pill. However, anyone who finds a lump in the breast or feels continuous pain needs to seek medical help.
Headaches: Migraines and headaches are a very common phenomenon of the birth control pill. Different types and doses of these pills may result in different headache symptoms.
Gaining weight: Experiencing certain fluid retention in the hip or breast area is very common. It also affects the fat cells of the body because of the oestrogen present in the pills.
Mood swings: Those with a history of stress or depression might start to feel the same again. If one has that kind of a history and starts to feel emotional changes, she should consult a doctor immediately.
Missing periods: It is a common side effect that after using the pill, one's period might get skipped. This is influenced by several factors including stress, depression or thyroid dysfunctions.
Decreased libido: The sex drive can be widely affected by the birth control pill. Although many other factors could result in a decreased libido, but if it remains after having the pill and is persistent, one should seek medical help or consult a specialist.
Vaginal discharge: There could be an increase or a decrease in the vaginal lubrication. Some people might experience vaginal discharge since it is very common. Changes in vaginal discharge never turn out to be harmful.
Changes in the vision: Fluid retention due to the birth control pill can result in the swelling of corneas. Because of this, even contact lenses do not fit comfortably. Contact lens wearers should consult an ophthalmologist if their vision or lens tolerance is disturbed.

Although there are certain side effects to taking birth control pills; however, one should not abstain from taking them in the fear that they might cause certain side effects. These pills are a precautionary measure along with other protection methods and should be taken in case someone wants to avoid pregnancy at the time being.

Side-effects of i-Pill Tablets - Every Woman Must Know!! 

It is important that you protect yourself from various types of diseases and infections as much as possible. Female condoms are used to have protected intercourse so as to avoid contact with ejaculatory fluids. These condoms help a person to steer clear of blood, semen and vaginal fluids as well. Female condoms fall under the category of barrier contraceptives. They are considered to be less effective in comparison to male condoms, but are nonetheless good for preventing any kind of infection. Ensuring fine health through safe sex is your due responsibility. Hence, a little knowledge about these contraceptives is helpful if you wish to shun chances of unwanted pregnancy or Sexually Transmitted Diseases. 

What is it like?
A female condom looks like an ill  fitting hollow cylinder. It is a thin sheath with a closed end, that goes inside the vagina and an open end that remains outside the vagina covering other external, genital parts. The covered end has to be inserted into the vagina or into the anus. It is a misconception, that female condoms can only be used by females. It is predominantly used by females, but can also be used by any receptive partner during sexual intercourse. The ends have circular rings to keep the condom in place. 

What are they made of? 
Femidoms are usually made up of polyurethane. This material is expensive, making the product costly. The need for a cost effective product was immediately felt to encourage the use of condoms among females. Thus, the next generation of female condoms were made with synthetic Nitrile. Nitrile proved to be a competent substitute as it did away with the annoying noises polyurethane made during sex. It also reduced condom pricing considerably. Researchers have also come up with natural latex female condoms that retain the feel of a male condom. 

Benefits of using a female condom
It is a great barrier in thwarting the flow of semen into the womb. Thus, they reduce the risk of accidental pregnancy. It also protects you against sexually transmitted infections like gonorrhoea, Syphilis, and HIV. Sex partners should be careful to refrain from any sexual contact before the insertion of a female condom. Only after the condom has been placed properly, the penis should enter the vagina or the anus. Femidoms are available in varied sizes, but the average sized condom fits most females. Large sized condoms can be used by new mothers. It is advised to buy condoms that bear the CE mark on them. The CE mark represents European Safety Standards and thus, leaves you least vulnerable to accidents or diseases.
