Birth control, also known as contraception, refers to methods and devices used to prevent pregnancy. It allows individuals to decide when or if they want to have children. There are a variety of birth control methods, each with different levels of effectiveness, side effects, and ways they work. 1. Types of Birth Control Methods A. Hormonal Methods Hormonal birth control methods work by altering a woman’s hormonal cycle to prevent ovulation, thicken cervical mucus, or thin the uterine lining to prevent pregnancy. Birth Control Pills (Oral Contraceptives): How it Works: Taken daily, birth control pills contain hormones (estrogen and progestin or progestin-only) that prevent ovulation. Effectiveness: 91% effective with typical use. Pros: Regulates menstrual cycles, reduces menstrual cramps, and lowers the risk of certain cancers. Cons: May cause side effects such as nausea, mood changes, and headaches. Contraceptive Patch: How it Works: A small patch worn on the skin that releases hormones (estrogen and progestin) to prevent pregnancy. Changed weekly. Effectiveness: 91% effective with typical use. Pros: Easy to use, only needs to be changed once a week. Cons: Can cause skin irritation and has similar side effects to birth control pills. Vaginal Ring (NuvaRing): How it Works: A flexible ring inserted into the vagina that releases hormones (estrogen and progestin). Worn for three weeks, then removed for one week. Effectiveness: 91% effective with typical use. Pros: Only needs to be changed monthly. Cons: Possible vaginal irritation, and similar side effects to other hormonal methods. Contraceptive Injections (Depo-Provera): How it Works: A progestin-only injection given every three months to prevent ovulation. Effectiveness: 94% effective with typical use. Pros: Long-lasting and doesn't require daily action. Cons: May cause irregular periods, weight gain, and a delay in return to fertility after stopping. Hormonal Intrauterine Device (IUD): How it Works: A small T-shaped device inserted into the uterus that releases progestin, which thickens cervical mucus and may stop ovulation. Effectiveness: 99% effective and lasts 3 to 6 years. Pros: Long-lasting, low maintenance, and very effective. Cons: Can cause irregular bleeding, and cramping during insertion.

Polycystic Ovarian Disease (PCOD), also known as Polycystic Ovary Syndrome (PCOS), is a common hormonal disorder that affects women of reproductive age. It is characterized by a combination of symptoms resulting from hormonal imbalances, and it can impact ovarian function, leading to irregular or absent periods, excess male hormones (androgens), and the development of small cysts on the ovaries. 1. Causes of PCOD The exact cause of PCOD is not known, but several factors are thought to play a role: Insulin Resistance: Many women with PCOD have insulin resistance, where the body’s cells don’t respond properly to insulin, leading to higher insulin levels. This can increase androgen production, disrupting the ovulation process. Hormonal Imbalance: Women with PCOD tend to produce higher levels of androgens (male hormones) like testosterone, which interfere with the normal development and release of eggs during ovulation. Genetics: PCOD tends to run in families, suggesting a genetic component. Low-Grade Inflammation: Research suggests that women with PCOD often have low-grade inflammation, which can stimulate polycystic ovaries to produce androgens. 2. Symptoms of PCOD The symptoms of PCOD vary, but common ones include: Irregular or Absent Periods: Infrequent or prolonged menstrual cycles are common in PCOD. Women may have fewer than eight periods a year or go months without a period. Excess Androgen Levels (Hyperandrogenism): High levels of male hormones can cause physical signs such as excess facial and body hair (hirsutism), severe acne, and male-pattern baldness (thinning of hair on the scalp).
