Restrictive dieting can sometimes cause women to stop ovulating. This is more significant than it might sound, because ovulation is the process through which women produce their key reproductive hormones. Without it, those hormones simply are not made.
Ovulation is a fundamental part of female biology. It is not only relevant to pregnancy. It plays an essential role in overall health, which means it should not be considered optional. For many women on hormonal contraception, this is an unseen trade-off: without realising it, they may be giving up a fundamental pillar of their health.
Understanding the importance of ovulation helps women make more informed decisions about their contraceptive options and their health more broadly.
The Health Benefits of Ovulation
Ovulation has an important relationship with general health. Ovulatory cycles both reflect health and contribute to it. Ovulation is increasingly recognised as a key marker of women's health and is often described as the fifth vital sign, because regular ovulatory cycles provide important insight into hormonal balance, nutritional status, and overall physiological wellbeing.
As a signal of health: Regular ovulation suggests that the body is functioning well. It typically indicates adequate nutrition and manageable stress levels.
As a contributor to health: Ovulation allows the body to produce progesterone each month. Progesterone and oestrogen are essential hormones for women, comparable in importance to testosterone for men.
Each ovulatory cycle provides a natural supply of progesterone, produced by the corpus luteum, a temporary structure that forms in the ovary after the egg is released. Ovulation is the only way the body makes progesterone. Over time, these repeated cycles help support bone strength and metabolic health, benefits that extend well beyond the reproductive years. For this reason, many experts believe that regular ovulation contributes meaningfully to long-term wellbeing.
Ovulation and Hormonal Contraception
Hormonal contraceptives prevent ovulation in most cases. While they contain progestins, these synthetic compounds are different from the body's natural progesterone and do not replicate the hormonal pattern of a natural ovulatory cycle. The bleed that occurs on the pill is a withdrawal bleed caused by stopping the medication, not a true menstrual period.
Historically, women may have ovulated less frequently because pregnancies occurred more often. Pregnancy itself produced hormonal changes that supported long-term metabolic reserves. Today, with fewer pregnancies and widespread use of hormonal contraception, many women ovulate far less across their lifetime than their biology was designed for.
How to Recognise Ovulation
Certain signs may suggest that ovulation has occurred or is likely occurring.
Possible indicators:
- Fertile cervical mucus (clear and stretchy, like raw egg white)
- A consistent monthly period
More reliable indicators:
- A sustained rise in basal body temperature during the luteal phase, typically around 12 to 16 days of elevated temperatures before menstruation
- Elevated progesterone levels confirmed through a blood test at the correct point in the cycle
It is important to note that a regular menstrual bleed alone does not guarantee ovulation. Some cycles can occur without releasing an egg. Tracking your cycle with Daysy or Lady-Comp and observing related symptoms can help you better understand your hormonal patterns.
Common Reasons Ovulation May Stop
1. Hormonal contraception: Many forms of hormonal birth control suppress ovulation and replace the natural cycle with a withdrawal bleed.
2. Polycystic Ovary Syndrome (PCOS): PCOS is a metabolic and hormonal condition often involving elevated androgen levels. It may cause irregular periods, missed periods, or anovulatory cycles.
3. Inadequate food intake: Hypothalamic amenorrhea occurs when the body stops menstruating due to insufficient energy intake, particularly low overall calories or carbohydrates. This is considered a protective adaptation to limited energy availability.
Other Factors That May Disrupt Ovulation
- Thyroid disorders
- Elevated prolactin levels
- Certain medications
- Nutrient deficiencies such as low zinc
- Food sensitivities such as gluten intolerance
- Dietary patterns that do not provide sufficient nutrients
Frequently Asked Questions
Why is ovulation important for women's health? Ovulation is essential because it is the only way the body naturally produces progesterone, a key hormone for bone strength, metabolic health, and overall wellbeing. Regular ovulation signals that the body has adequate nutrition and manageable stress levels, making it both an indicator and contributor to good health.
Can you have a period without ovulating? Yes. It is possible to have menstrual bleeding without ovulation. This is called an anovulatory cycle. A regular bleed alone does not confirm that ovulation occurred. A sustained temperature rise or elevated progesterone on a blood test are more reliable indicators.
How can I tell if I am ovulating? The most reliable indicators are a rise in basal body temperature sustained for around 12 to 16 days before your period, and elevated progesterone on a blood test. Other signs include fertile cervical mucus and regular monthly periods, though these alone do not confirm ovulation. Fertility trackers like Daysy can help you identify these patterns.
What causes ovulation to stop? Common causes include hormonal contraception, PCOS, inadequate calorie or carbohydrate intake (hypothalamic amenorrhea), thyroid disorders, elevated prolactin, certain medications, and nutrient deficiencies such as low zinc.
Does the birth control pill stop ovulation? Yes, most hormonal contraceptives suppress ovulation. While they contain synthetic progestins, these do not replicate the body's natural progesterone or provide the same health benefits as a natural ovulatory cycle.
What is progesterone and why does it matter? Progesterone is a reproductive hormone produced only through ovulation. It supports bone density, metabolic health, and overall wellbeing throughout life, not just during reproductive years. Each ovulatory cycle provides a natural monthly supply of this essential hormone.
