Ovaries are a pair of reproductive organs on either side of the uterus. Their main function is releasing an egg every month and producing female hormones, such as oestrogen and progesterone, which help regulate periods and mood and are crucial for pregnancy and bone health
In this article, the function of the ovaries is explained not in medical terms but using the analogy of a monthly school project. The female body represents the school, and the ovaries are the teachers who assign a project (a possible pregnancy) every month. Irrespective of whether you are considering pregnancy (whether the assignment will be selected for a presentation at the end of the month), the ovaries plan, prepare and evaluate this monthly assignment. So, let’s begin to understand the function of the ovaries using the monthly school project analogy.
The monthly project comprises four main stages, similar to a school project, which involve the school announcing the project, followed by planning and preparation, submission, and feedback.
The first day of the period is considered Day 1 of your menstrual cycle. It is like the ovaries (teacher) telling the body (school) that last month the project was unsuccessful (no conception), so they are starting fresh.
The uterine lining is shed in the form of a period. This is similar to a classroom where the desks are cleared up to start preparation for a new assignment. The school principal (brain) sends an announcement through the follicle-stimulating hormone (FSH) to start preparation for a new project. The ovaries (teachers) are given the responsibility to choose and prepare a new egg (student) for the month.
Following the announcement by FSH, each follicle containing one egg (student) starts preparing itself, as only one egg gets selected by the ovaries (students prepare themselves to be chosen as the project leader). The “chosen egg” releases oestrogen to prepare the body for a pregnancy by thickening the uterine lining. It is like decorating the classroom to welcome a special guest (fertilized egg). Oestrogen also informs the brain that the egg is ready to be released.
When the egg matures, the luteinizing hormone (LH) is released. Increased LH levels promote ovulation; the mature egg is released into the fallopian tubes, where it could encounter a sperm. This is like a project being submitted and waiting to see if it is accepted (fertilization).
The ruptured follicle that released the egg transforms into the corpus luteum. The corpus luteum produces progesterone, preparing the uterus to accommodate the fertilized egg (classroom continues to be decorated as the result of project selection is awaited). This is similar to a teacher giving extra support just in case the project (fertilisation) was successful.
According to gynecologists, if fertilisation occurs, the progesterone levels continue to increase to maintain the early stages of pregnancy (project is accepted). If fertilization fails to occur, progesterone is no longer produced. The uterus sheds its lining, marking the start of the next period. This is similar to cleaning the classroom and awaiting the next assignment.
Understanding ovarian function is important for the following reasons:
Some ways to ensure the smooth functioning of the “monthly project”:
The ovaries, along with their team (hormones and other reproductive system components), work hard to ensure your period arrives on schedule or prepare your body for a possible pregnancy. They are similar to teachers who work hard to assign and manage a project every month.
Using a monthly school project as an analogy for ovarian function allows you to understand the different phases of your menstrual cycle and its importance for your overall well-being. Awareness of ovarian function helps you make healthy choices to support your health in every phase of life.
Understanding how the ovaries function can help women become more aware of their menstrual health, hormonal balance, and overall well-being. Recognising changes in your cycle and seeking timely medical advice can support better reproductive health.

What is the main function of the ovaries?
The ovaries release an egg every month and produce hormones like oestrogen and progesterone, which regulate periods, mood, and overall reproductive health.
How does the menstrual cycle work in simple terms?
The cycle has four stages: menstruation (period), preparation of the egg, ovulation (egg release), and waiting phase. If no pregnancy occurs, the cycle resets.
Why is ovulation important?
Ovulation is when the ovary releases a mature egg. It is the key phase for fertility and also indicates that hormonal balance is functioning properly.
What causes irregular periods?
Irregular cycles can be due to stress, hormonal imbalance, thyroid issues, or conditions like PCOS. Monitoring patterns helps identify underlying causes early.
How can I keep my ovaries healthy?
A balanced diet, regular exercise, good sleep, and stress management help maintain hormonal balance and support ovarian function.
Does ovarian function affect overall health?
Yes. Ovarian hormones influence mood, energy, bone health, skin, and heart health. Changes in function can impact multiple body systems.
At what age does ovarian function start to decline?
Ovarian function gradually declines in the late 30s and more rapidly as menopause approaches, typically in the late 40s or early 50s.
