A deepfake video is a type of synthetic media in which a person in an existing video is replaced with someone else’s likeness. This is typically done using artificial intelligence (AI) techniques, such as machine learning and face-swapping.
Deepfake videos have the potential to be used for a variety of purposes, both good and bad. On the one hand, they can be used to create realistic and believable simulations of events that never actually happened. This could be used for educational or entertainment purposes, or even for more nefarious purposes, such as spreading misinformation or propaganda.
On the other hand, deepfake videos can also be used to create harmful and misleading content. For example, they could be used to create fake news articles or videos that appear to show people saying or doing things they never actually said or did. This could have a serious impact on public discourse and trust in institutions.
In India recently famous actress Rashmika Mandanna deepfake video gone viral on various social media platforms. Originally the video is of Zara Patel, a British-Indian influencer, but her face was replaced with the face of the actress using deepfake technology.On her statement she told that she shared the video on 9th Oct 2023 in Instagram post with the caption, ”POV: you almost close the elevator door on me again….”
How to Spot Deepfakes?
Visual inconsistencies:
Unnatural facial expressions and movements: Deepfakes may have subtle inconsistencies in facial expressions and movements, such as blinking too often or too little, or having unnatural facial hair or jewelry.
Poor lip-syncing: Deepfakes may have poor lip-syncing, where the movement of the person’s mouth does not match the audio.
Inconsistent lighting and reflections: Deepfakes may have inconsistent lighting and reflections, where the person’s face or hair appears different from the background.
Low-quality video or audio: Deepfakes may be low-quality video or audio, especially in areas where the AI has had difficulty replicating reality.
Audio inconsistencies:
Unnatural pauses or hesitations: Deepfakes may have unnatural pauses or hesitations in the speech, especially when the AI is transitioning between different audio sources.
Background noise or inconsistent audio levels: Deepfakes may have inconsistent background noise or audio levels, where the audio quality varies throughout the recording.
Repetitive speech patterns: Deepfakes may have repetitive speech patterns, where the AI is using a limited dataset of audio to create the speech.
Contextual clues:
Consider the source of the video: Be skeptical of videos from sources you are not familiar with or that have a history of sharing misinformation.
Check for other versions of the video: If you see a video that seems suspicious, try to find other versions of the video or audio to compare it to.
Consider the person in the video: Does the video make claims or statements that the person in the video would not typically make?
Be aware of your biases: It is important to be aware of your own biases when evaluating a video or audio recording. Deepfakes can be used to exploit these biases and make people believe things that are not true.

Nowadays Educated and aware married couple use different methods of family planning and it can be effectively done by the use of contraceptives.
Contraceptives, also known as birth control methods, are medications or devices that are used to prevent pregnancy. They work by interfering with the normal reproductive process in various ways. There are many different types of contraceptives available, each with its own advantages, disadvantages, and suitability for different individuals and couples.
Types of Contraceptives
Contraceptives can be broadly classified into two main categories :
Hormonal Methods
Barrier Methods
Hormonal methods work by releasing hormones that disrupt the normal menstrual cycle and prevent ovulation, the release of an egg from the ovary. These methods include:
Combined oral contraceptives (COCs): These pills contain a combination of estrogen and progestin hormones. They prevent ovulation, thicken cervical mucus to make it more difficult for sperm to reach the egg, and thin the lining of the uterus to make it less receptive to implantation.
Progestin-only pills (POPs): Women who cannot take estrogen progestin-only pills strictly recommended by health workers . They work by thickening cervical mucus and thinning the uterine lining.
Implants : Implants are small, flexible rods are inserted under the skin of the upper arm and release progestin over a period of 3 to 5 years
Intrauterine devices (IUDs): IUDs are small, T-shaped devices are inserted into the uterus and release either progestin or copper. They can prevent pregnancy for up to 10 years.
Injections: These injections contain progestin and are administered every 3 months.
Barrier methods work by physically preventing sperm from reaching the egg. These methods include:
Condoms: Condoms are thin, flexible sheaths are worn over the penis to prevent sperm from entering the vagina. This method is also effective in preventing the transmission of sexually transmitted infections .
Diaphragms: Shallow cups made of silicone are inserted into the vagina before intercourse to cover the cervix and prevent sperm from entering the uterus are called Diaphragms.
Cervical caps: These small, dome-shaped cups are made of silicone or latex and are inserted into the vagina before intercourse to fit over the cervix and prevent sperm from entering the uterus.
Spermicides: These foams, gels, creams, or films contain chemicals that kill sperm. They are often used in combination with other barrier methods, such as condoms or diaphragms.
Effectiveness of Contraceptives
The effectiveness of different contraceptives varies. The most effective methods are implants, IUDs, and injections, which have a typical use failure rate of less than 1%. Oral contraceptives, vaginal rings, and the patch have a typical use failure rate of about 3%. Barrier methods are less effective, with condoms having a typical use failure rate of about 2% and diaphragms and cervical caps having a typical use failure rate of about 6%.
The effectiveness of contraceptives can also be affected by how well they are used. For example, if pills are not taken at the same time each day or if condoms are not worn correctly, their effectiveness can be reduced.
Advantages and Disadvantages of Contraceptives
Each type of contraceptive has its own advantages and disadvantages. Some of the general advantages of contraceptives include:
They can prevent pregnancy, which can help to reduce the risk of unplanned births and abortions.
They can help to regulate menstrual cycles.
Some methods can be expensive.
Most of the methods may not be suitable for everyone, such as women with certain medical conditions.
Choosing a Contraceptive
The best contraceptive for a woman depends on her individual needs and preferences. It is important to talk to a healthcare provider to discuss the different options and find the method that is right for her.
Additional Considerations
In addition to the type of contraceptive, there are other factors to consider when choosing a birth control method. These factors include:
Medical history: A healthcare provider will review a woman’s medical history to determine if there are any medical conditions that could be affected by contraception.
Sexual history: A healthcare provider will also discuss a woman’s sexual history to determine her risk of STIs and recommend appropriate protection.
Lifestyle: A healthcare provider will consider a woman’s lifestyle, such as her smoking habits and alcohol consumption, when recommending a contraceptive method.
Cost: The cost of different contraceptives can vary significantly.
Contraceptives are an important tool for women who want to control their fertility and prevent unplanned pregnancy.

Be gentle when opening the package to avoid damaging the condom.
Find a Comfortable Position:
Many women find it easier to insert the female condom while squatting, standing with one foot elevated, or lying down.
Squeeze the Sides of the Inner Ring:
With the closed end of the female condom, squeeze the sides of the inner ring together to make it long and narrow.
Insert the Closed End:
Gently insert the closed end of the condom into the vagina, pushing it as far back as it will go. The inner ring should rest against the cervix.
Ensure the Outer Ring Covers the Vulva:
The outer ring should cover the area around the vaginal opening, providing additional protection.
During Intercourse:
The penis should be guided into the condom, ensuring it stays inside the condom throughout intercourse.
After Intercourse:
After intercourse, twist the outer ring to prevent spillage and gently pull the condom out. Dispose of it properly.
