Biology Project On Sanitary Pads For Class 12

Introduction To Menstruation

Menstruation is an essential aspect of a woman’s reproductive cycle and a normal occurrence in the female reproductive system. It’s when your uterine lining naturally sheds after being shed every 28 days. often, menstruation starts between the ages of 9 and 16 and lasts until menopause, which often happens between the ages of 45 and 55.

The pituitary gland and the ovaries work together to regulate a woman’s menstrual cycle. The follicular phase, ovulation, the luteal phase, and menstruation are the four stages that make up a woman’s monthly cycle. Beginning on the first day of menstruation, this phase typically lasts for 14 days. Follicle-stimulating hormone (FSH) is produced by the pituitary gland and promotes oestrogen production by the ovaries during this period. When a woman takes oestrogen, her uterine lining thickens so that a fertilised egg may attach to it.

About halfway through a woman’s menstrual cycle, she will ovulate, at which point a mature egg will be discharged from one of her ovaries. The pituitary gland’s increased production of luteinizing hormone (LH) stimulates ovulation.

After an egg is fertilised, a woman goes through the luteal phase, which typically lasts for 14 days. The empty follicle in the ovary from whence the egg was discharged transforms into a structure known as the corpus luteum at this time. Produces progesterone, which thickens the lining and paves the way for the fertilised egg to grow.

During menstruation, the endometrial lining is shed if fertilisation does not take place, and the corpus luteum degenerates, resulting in a decrease in progesterone levels. A woman’s uterus releases blood and other components over the course of three to five days during menstruation.

Menstrual hygiene and the usage of sanitary pads are vital, but they are best understood in the context of the menstrual cycle and its stages. Maintaining clean menstruation practises helps protect against infections and boost reproductive health.

Types Of Sanitary Pads

Pads for feminine hygiene come in a variety of styles and materials to accommodate a wide range of women’s requirements and preferences. Typical feminine hygiene products include:

Regular Pads: Regular pads are the most widely available option and are best suited for light to moderate periods. They come in a variety of thicknesses and sizes and are often backed with plastic to seal off any potential leaks.

Overnight Pads: Extra protection is provided with overnight pads, which are ideal for nights with a high flow. It’s no secret that the average person’s attention span is less than that of a goldfish.

Ultra-Thin Pads: Thinner than traditional pads, ultra-thin ones have the dual benefits of being less noticeable and more pleasant. They’re at their best in conditions of mild to moderate current and may have wings for increased security.

Pantyliners: As an alternative to tampons or menstrual cups, or on days when you have a very mild flow, you may use a pantyliner. They may also be used on a regular basis to deal with mild spotting or vaginal discharge.

Organic Pads: Organic pads are devoid of synthetic chemicals and scents and are crafted from all-natural materials like cotton, bamboo, or other plant fibres. Those who have allergies or sensitive skin might benefit from using them.

Scented Pads: Pads with added fragrances are intended to cover up unpleasant odours associated with menstruation, however they may include compounds that are irritating to the skin or even allergenic. If your skin is very delicate or you suffer from allergies, you should avoid using scented pads.

Reusable Pads: Washable and reusable pads are better for the environment and your wallet. They come in a variety of sizes and degrees of absorbency, and are often crafted from all-natural materials like cotton, bamboo, or hemp.

The best sanitary pad is the one that matches your flow and activity level while yet being pleasant to use. To avoid getting an infection during your period, it’s best to replace your pad every four to six hours.

Composition And Functioning Of Sanitary Pads

To achieve their intended functions of absorption, comfort, and leak prevention, sanitary napkins are constructed from many layers of different materials. The many strata and the tasks they perform are described below.

Top Sheet: The top sheet is the sheet that makes direct touch with the sleeper’s skin. Cotton or synthetic fibres are common materials used to make it soft and breathable. The menstrual fluid is able to travel through the top layer and be absorbed by the pad underneath.

Absorbent Core: The menstrual fluid will be absorbed by the absorbent core. Superabsorbent polymers (SAPs) or wood pulp are often used as the main ingredients because of their high capacity to soak up liquids.

Leak-Proof Layer: Polyethylene or polypropylene, two types of plastic, are often used to make the leak-proof layer. As a matter of fact, it is the exact opposite of what you may think.

Adhesive Strip: You may attach the pad to your pants with the help of the adhesive strip that can be found at the pad’s base. Typically, a skin-friendly adhesive material is used.

Wings, which are flaps on the sides of the pad that fold over the borders of the pants to give further leak protection, and smell, which is added to hide menstruation odour, are two examples of the extra characteristics that may be found on certain pads.

Pads work by capturing and containing menstrual fluid inside their absorbent centre. The fluid cannot escape through the pad’s bottom and stain garments thanks to the waterproof barrier. The pad stays in place and doesn’t bunch up thanks to the adhesive strip that sticks it to the pants. A new pad should be used after the first 4-6 hours, or whenever the pad has achieved its maximum absorbency.

Picking a pad that works for your flow and degree of exercise while yet being comfortable is essential. Changing your pad often might help you keep your period clean and free of infections.

Health And Environmental Concerns

There are certain health and environmental problems linked with the use of sanitary pads, despite the fact that they are a handy and efficient option for regulating menstrual flow.

Health Concerns: Safety Issues The adhesive or synthetic fibres used in sanitary pads may cause skin irritation or allergic responses in certain people. The risk of irritation or infection may also be raised by the use of scented pads or pads containing scents. If you have sensitive skin or allergies, it’s best to stick to pads produced from natural materials and steer clear of scented options.

Environmental Concerns: It’s bad for the environment since most sanitary napkins are made of plastic, which may take hundreds of years to degrade. Pads may also be a source of environmental contamination during production and disposal. Pads manufactured from biodegradable materials or pads that can be cleaned and reused numerous times are two types of environmentally friendly products that manufacturers are presently manufacturing. These alternatives are better for the environment and might end up saving money.

Toxic Shock Syndrome (TSS): Tampons and menstruation cups have been linked to an uncommon but possibly fatal illness known as toxic shock syndrome (TSS). However, if sanitary pads are used and remained in place for an extended period of time, they may potentially cause TSS. Fever, nausea, vomiting, a rash, and low blood pressure are among symptoms of TSS. Regular pad changes and good menstrual hygiene are key in preventing toxic shock syndrome.

In general, you should choose sanitary pads based on their softness, absorbency, and safety for your health and the environment. Menstrual hygiene entails more than just changing pads often and cleaning hands before and after using sanitary goods.

Importance Of Access To Sanitary Pads

Having regular access to sanitary pads is essential for women’s health and well-being. Some of the many benefits of having easy access to feminine hygiene products include:

Health and Hygiene: Infections and other health issues related to menstruation hygiene may be avoided when sanitary pads are used. Women and girls are more likely to maintain good personal hygiene and health when they have access to safe menstruation products.

Education: Missing school or even dropping out entirely because of menstruation may have a devastating effect on a girl’s educational and professional prospects. Girls are more likely to complete their education, do better in class, and go on to achieve their objectives if they have access to sanitary pads.

Empowerment and respect: menstruation is a normal physiological process that should not be seen as taboo or shameful. Providing women and girls with sanitary products might help them regain their self-respect and confidence.

Economic Opportunity: Women’s economic opportunities may be hampered if they are unable to get menstruation supplies. Women may lose out on career chances and money when they are forced to take time from work because of their periods or cannot afford menstruation products.

Human Rights: Access to menstrual hygiene products is an issue of human rights. In order to achieve gender equality and protect fundamental human rights, it is crucial that women and girls have access to low-cost, high-quality menstruation products.

Health, education, dignity, empowerment, economic opportunity, and human rights are all bolstered when women and girls have access to sanitary pads. It is the responsibility of governments, organisations, and people to guarantee that all women and girls, regardless of their socioeconomic status, geographic location, or cultural background, have access to sanitary menstruation products.


It’s safe to assume that most people would agree that having a reliable sanitary pad is a necessity in the modern world. Women may get the best sanitary pad for their requirements by learning about the many options available. The risk of infection and other health issues may be reduced by using these products responsibly, and by adhering to good menstrual hygiene practises.

In addition, ensuring women have access to sanitary products is important for advancing women’s health, literacy, independence, economic security, and human rights. The advancement of women’s rights and the protection of girls’ health depend on the availability of sanitary menstruation products. To guarantee that no girl or woman is left behind, it is imperative that governments, organisations, and people collaborate to find solutions to the problems associated with menstrual hygiene management.

A more just and equitable world for all women and girls may be achieved by spreading awareness about the value of sanitary pads and working towards their widespread availability.
