To study family planning devices II BPharma Experiment 3 HAP 2 Sem 2 AKTU II Sehat Aur Shiksha

Experiment Number – 3

Aim:- To study family planning devices.

Reference:-

Theory:- Family planning or birth control is the process to prevent fertilization of ovum and sperm and thereby avoid pregnancy using various devices or medicines. Looking at long-term effects with minimum side effects use of devices is more common than the consumption of medicines.

 

The various family planning devices are as follows:-

1. Barrier Devices

2. Intrauterine devices (IUDs)

3. Implants

 

(1) Barrier Devices:-  These devices are designed to prevent access of sperms to the female reproductive tract.

(a) Male Barrier Devices:-

Male condom: The condom is the most widely used device by males. It is a non–porous elastic rubber sheath worn over the erected penis prior to the start of physical intercourse which physically blocks ejaculated sperm from entering the female reproductive tract. In addition, it gives protection against sexually transmitted diseases (STDs) like AIDS, Syphilis, and gonorrhea. It is a very cheap and highly effective contraceptive device.

 

(B) Female barrier devices:

1. Diaphragm:- It is the rubber dome structure that is fitted over the cervix by the female with or without spermicidal jelly. It is made from latex, silicon, or natural rubber. It works either by blocking access of sperm to the cervix or by killing them with spermicide.

2. Female Condom:-  Female Condom is also called a vaginal pouch and is made up of two flexible rings connected by nitrile, latex, or polyurethane sheath. One ring lying inside the sheath is inserted to fit in the cervix and the other ring remains outside the vagina and covers the external genitals. Use of appropriate creams, jellies, foams, suppositories, etc. in the female before intercourse, may be combined with barriers.

3. Sponge:- It is a sift foam containing spermicide which is inserted into the vagina to cover the cervix. It must be moistened with water to activate spermicide that kills sperms and present their entry into the cervix. It should not be kept in Vagina for more than 30 hours.

4. Cervical Cap:- It is made up of silicone which fits over the cervix and blocks sperm from entering the uterus through the external orifice of the uterus.

 

(2) Intrauterine Devices (IUDs): IUDs are made up of either plastic or metal that are placed in the uterus. IUDs are of two types viz. Non – Hormonal copper IUDs and Hormonal IUDs. Copper IUDs (Copper T) work by disrupting sperm mobility and damaging sperm by its spermicidal action. The hormonal IUDs contain progesterone which acts by blocking the endometrial proliferation making it unsuitable for fertilization and preventing sperm penetration by increasing the viscosity of cervical mucus. IUDs have a major advantage of long-term use (6 – 10 years) with the flexibility to remove when desired.

 

(3) Implants:- These are small tubes that are placed under the skin of the upper arm. Hormones from these tubes prevent sperm from appearing egg and inhibit the release of an egg.
