Product information

Zoely is an oral birth control pill made by Theramex. It is taken every day, and prevents pregnancy by supplementing the body’s natural levels of the hormones progesterone and oestrogen, with synthetic hormones, called nomegestrol acetate and estradiol. In doing this, it prevents the process of ovulation, and reduces the likelihood of pregnancy.

  1. Simple to take one a day tablet
  2. Provides 99% effective protection
  3. Adept at reducing menstrual tension

How does Zoely work?

Hormones perform an important function in the body, by regulating when it is ready to conceive. As levels of progesterone and oestrogen raise and lower each month, conditions in the reproductive system change to allow for a baby. One phase the body goes through is ovulation. This is where the ovary releases an egg, which is then available for fertilisation by male sperm.

The egg, whether it has been fertilised or not, travels to the uterus. If fertilised, it implants on the uterine wall; if it isn’t, it simply disintegrates and is discharged along with the lining of the uterine wall (known also as the endometrium) though menstrual bleeding. Hormones play a role in this aspect of the conception process too; oestrogen manages the build up of the uterine wall lining, while progesterone is responsible for its shedding each month.

Levels of these hormones are topped up as they fall by those supplied through contraceptive medicine; nomegestrol and estradiol thereby trick the body into thinking that the peak time for conception has already passed. This stops ovulation from happening, and makes the lining of the uterus less receptive to egg implantation. It also makes the natural mucus found inside the vagina thicker, and this stops sperm from being able to move around as easily once inside.
