What are the latest advancements in male contraceptions?

The drawback of surgical approaches (such as vasectomy), especially patient compliance and the low success rates with condoms has spurred research on hormonal contraceptive dosage forms. There is a dearth of investigations in the development of pharmaceutical preparations. Evolving technology in the 21st century as well as improvement in living standards further underline the need for new male contraception approaches, especially those that entail new drug delivery methods.

Here are few areas where male contraception is being researched and used in some countries

Hormonal contraception for men is possible, and we are at the threshold of an important breakthrough. Combined testosterone plus progestin administration is more effective and safer than testosterone alone. Combination of testosterone plus an anti-androgenic progestin has several advantages over other formulations. In combined therapy, single injection formulation may have better compliance. 

Conventional male contraception 
Abstinence (doesn't work well)
Masturbation
Male condom
Vasectomy
There are other methods being developed but not sure they are there yet. But for guys? Their options are stuck in a time warp. If a man wants to take pregnancy prevention into his own hands, his choice basically comes down to condoms, a vasectomy, withdrawal, or abstinence. That s why it's so amazing that scientists are finally developing some real advancements when it comes to male contraception.

Researchers writing in the April issue of the Open Access Journal Contraception published a rundown of the top emerging options. A few hold real promise, particularly a daily or weekly pill that would deliver a dose of artificial hormones to a guy s bloodstream, which would then act on reproductive hormones to stop sperm from being produced. Like the female hormonal pill, the male hormonal pill would be reversible. But also like the female hormonal pill, there appear to be side effects, among them acne, weight gain, and even trickier to work around, changes in testosterone levels that trigger a plunge in libido.

Non-hormonal techniques are also being developed, particularly a vaccine that immunizes men with antibodies to halt sperm production. This so-called male birth-control shot is encouraging, because it targets sperm directly (rather than targeting other hormones in the body) and doesn t have the testosterone-lowering side effects of a hormonal pill. Each injection would last for long intervals (experts aren t yet sure how long), but the pregnancy-preventing effects would be reversible, if and when a guy decides he s ready to be a dad.

So when can you expect to see men rushing out to the pharmacy counter to pick up their new birth control Rx?  I think we may see a novel male contraceptive within 10-12 years, That may seem far off, but hey at least it s finally within sight.

Male Contraception - An Insight!

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.

4 Types of Contraception for Birth Control

There are a number of contraceptives available but which method of birth control suits you depends on your sexual life, preferences and your lifestyle as a whole. Professional medical help should be sought in order to understand what method of contraception sis ideal for you.

Here is a list of 4 types of contraceptives for birth control.

1. Barrier methods

Barrier methods are designed to prevent the sperm from entering the uterus. They constitute-

- Diaphragms: It is a shallow and flexible cup that is made of either latex or soft rubber. It is inserted into the vagina before the sexual intercourse where it prevents the sperm from entering the uterus.
- Cervical caps: It is a thin cup of silicone whose function is same as the diaphragm, only it is smaller in size, so less noticeable and more rigid as well.
- Contraceptive sponges: These are soft foam sponges that are filled with spermicide and are disposable. They are also inserted into the vagina before sexual intercourse in order to prevent pregnancy by killing the sperm cells or preventing them from entering the vagina.
- Spermicides: These are chemicals that can kill the sperm and hence assist in birth control.

Other methods include male condoms and female condoms.

2. Hormonal methods

Hormonal methods use hormones in order to either stop or regulate ovulation so as to prevent pregnancy. There are various methods through which hormones can be injected into the body. Some of them are-

- Contraceptive patch: It is a thin patch made of plastic that sticks to the skin and is responsible for releasing hormones into the bloodstream through the skin.
- Vaginal rings: A thin, flexible ring that is inserted into the vagina where it stays for 3 weeks and is removed after that, only to be re-inserted in the 5th week.
- Implantable rods: They are inserted under the skin of the upper arm of women where they release progestin.

Other methods include contraceptive pills and progestin-only pills.

3. Intrauterine methods of contraception

The intrauterine device is a small device, T-shaped that is inserted into the uterus in order to prevent pregnancy. The good thing about intrauterine devices is that they can remain functioning for many years at a stretch. IUDs are two types-

- Hormonal IUD(Intrauterine Device)
- Copper IUD

4. Sterilization

Sterilization is the most reliable contraceptive for birth control as it is permanent. It either prevents the release of sperm or the fertilization of the egg. Sterilization methods can either be surgical or non-surgical. Some of the sterilization techniques are-

- Tubal ligation: It is the surgical technique used in females.
- Vasectomy: It is the surgical technique of male contraception.

Other methods include sterilization implants.



4 Types of Contraception for Birth Control

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.

Birth Control Pills - 10 Common Side Effects of Them!

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

Female condoms are generally pouches made of latex and polyurethane, which are used by women during sex in order to prevent pregnancy and thereby reduce the chances of infection by sexually transmitted diseases. Each end of these pouches are made of rings that are flexible. They should be inserted deep inside the vagina before sex is initiated and held in the position by utilizing the rings available at the closed end while the rings which are at the open end remain outside the vagina during sex.

Even though it can be safely used by most people, some women would find female condoms to be an inappropriate form of contraception and would not feel comfortable with their genital areas being touched. Thus, it is very important that the appropriate form of contraception be considered for you and your partner. Condoms should be used correctly. In case of need for extra protection, other options of contraception should be considered.

Pros of female condoms
1. Since the exchange of bodily fluids, such as semen and vaginal fluid is prevented, female condoms aid in offering protection against many sexually transmitted diseases such as HIV.

2. Condoms can prove to be reliable pregnancy averting methods if they are properly and consistently used.

3. Female condoms are only needed during the time of sex. Any form of advance preparation is not required, hence making them suitable for unplanned sex.

4. Prescriptions are not needed

5. The condoms are usually small in size, disposable as well as easy to carry

6. Usually, using condoms does not show any medical side effects.

7. Insertion of female condoms can be done up to a duration of eight hours before sex. The responsibility for utilizing condoms properly should be shared by the woman as well as the partner.

Cons of female condoms
1. Even though condoms are generally very strong, they are prone to splitting or tearing in case of improper use.

2. Availability of female condoms pales in comparison to the male counterparts and they are usually more expensive.

3. The outer ring might produce a cumbersome feeling.
