Period Glossary


Tampons are a menstrual hygiene product that is inserted into the vagina during menstruation. Its purpose is to prevent menstrual fluid from leaking onto clothes. There are organic and non-organic tampons. Tampons come in different absorbances such as light, regular, super and super plus.  

Non-organic tampons are made from non-organic cotton and synthetic fibers. They can include ingredients such as chlorine, bleach, pesticides and by-products such as dioxin. They can be inserted with or without an applicator and absorb your menstrual fluid for 3-6 hours.  It’s important to change your tampon frequently as the bacteria can cause TSS.

Organic tampons are made with only 1 ingredient- 100% organic cotton. Organic tampons are similar to other tampons on the market aside from their ingredients.  They can be inserted with or without an applicator and absorb your menstrual fluid for 3-6 hours. It’s important to change your tampon frequently as the bacteria can cause TSS.   

Bio-plastic tampons applicators are made with 90% sugar cane and 10% plastic these tampon applicators are similar to normal plastic applicators but better for the environment.

Cardboard tampon applicators are similar to a plastic applicator in shape and size, but made of cardboard and are 100% biodegradable, making them the environmentally friendly applicator option.

Plastic Tampon Applicators are similar to cardboard applicators in shape and size, however they slide in easier because of the plastic material.

Pad also referred to as sanitary napkin, sanitary towel, sanitary pad, and menstrual pad is an absorbent item worn outside the body to absorb your period. The pad has an adhesive side that is attached to the underwear. Pads come in different absorbances and can have wings or no wings.

Reusable pads are made from cloth. They are similar to normal menstrual pads, however since they are made from cloth they are washable and reusable.

Menstrual cup is a silicone product that is inserted into the vagina when we’re menstruating. Its purpose is to collect menstrual fluid while inside the vagina and keeps it from leaking onto clothes. Unlike tampons and pads, a menstrual cup collects menstrual fluid rather than absorbing it.  It can be worn for up to 12 hours and should be sanitized between wears. One menstrual cup can last up to 5 years.

Menstrual disc is a reusable period product sits in the vaginal fornix, which is at the base of your cervix. It is at the widest part of your vaginal canal. The menstrual disc collects your period rather than absorbing it. Also, menstrual discs don’t block the vaginal canal, as they sit further into your body so it is possible to have sex while wearing it.

Period underwear are a product worn outside the body, like regular underwear to collect and absorb your period. The underwear includes an absorbent layer to prevent leaks from a pad or tampon. They are washable and reusable. Some brands even offer period underwear that can hold up to 2 tampons worth of menstrual blood.

Free-bleeding is a movement in which menstruators avoid the use of pads, tampons or other products that are usually used when menstruating.  Free bleeders openly bleed into their garments to raise awareness of the reality of the stigmatization of menstruation and to stand in solidarity with those who may not be able to afford menstrual hygiene products.

Bra is an article of clothing usually worn under a shirt to support your breasts and allow for equal weight distribution to reduce discomfort. Bras aren’t mandatory and it’s your choice to wear one or not.



Cervix: is the opening into the uterus.

Uterus also known as the womb, is a hollow, pear-shaped muscular organ. It is normally where the fertilized egg is implanted, and where the fetus develops. During pregnancy the uterus expands to about 500 times its prepregnancy size.

Vagina is the muscular tube leading from the external genitals to the cervix of the uterus in females.

Vulva: When people refer to the "vagina," what they usually mean is the vulva, which includes all the external parts, including the inner and outer lips.

Labia Majora/Outer Lips: These are the first things you see, and hair grows on them naturally. The labia majora's job is to protect the more sensitive parts inside.

Labia Minora/Inner Lips: The labia minora provide the second layer of protection for the underlying structures and openings, and they also have oil glands that secrete lubrication to keep you comfortable. Just know that the lips might not be symmetric, they might extend beyond the labia majora, and the edges might not be totally smooth. The labia minora is like our fingertips, unique for everyone.

Clitoris and Clitoral Hood: The clitoris, which is the little nub you see at the top of your external area when you spread the labia, contains 8,000 nerve endings. The hood, a flap of skin that slides back and forth, functions to protect the clitoris and prevent irritation and arousal when you don't want it. When you are aroused, however, the hood slips back to expose the clitoris.

Urethra: This small opening, which is where urine comes out, is right below the clitoris. It's hard to see and you can't really feel anything there.

Vestibule: Right below the urethra lies the opening to the vagina. Basically, the vestibule is the lobby leading to the vagina, which is inside your body. We should also say here that there are many color variations in the whole external vulva area, depending on your skin tone and whether or not you're sexually excited.

Fallopian Tubes and Ovaries: Every month your ovaries shoot out an egg and send it floating happily down the uterus where it will hang around in hopes of meeting up with some sperm to make a baby.

Internal Clitoris (crura): You have a wishbone-shaped structure extending from your clitoris on the outside of your body—the top of the wishbone—to the area under your labia majora deep inside. It's tissue that engorges during sexual arousal and that is excitable. So there's literally much more to female sexual excitement than meets the eye.

G-spot or Grafenborg spot is an area about two knuckles length deep on the top of the vagina. For some women, it can produce sexual pleasure when stimulated.

Sperm are the male reproductive cells that our find in semen.

Semen is the white, sticky fluid that is released during ejaculation.

Ejaculate is the fluid containing sperm that is released from the tip of the penis during ejaculation.

Foreskin is the retractable area of skin that covers the head of the penis.  If a male is circumcised, this is the skin that is removed.

Testicles (balls) are the gland in which sperm and the hormone testosterone are produced.

Testosterone is the hormone made by the testes that is responsible for changes to boy’s bodies like facial hair. Testosterone is also produced the in ovaries for girls, but in much smaller amounts.

Scrotum is the loose bag of skin beneath the penis that hold the testes and regulate their temperature.

Circumcision is the surgical removal of the foreskin from the head of the penis.
