Let’s be honest, how many times have you been asked, “Is it your hormones?” when you’ve been feeling a bit off? It’s not exactly the most helpful question, and it’s often said in the wrong tone—but frustrating as it is, hormones really do play a huge role in how we feel and how our bodies function.
As women, we’re no strangers to the effects of hormones. From mood swings to cramps, periods are a monthly reminder that our hormones are doing their thing. But how much do we actually know about them? Most of us have heard the terms “oestrogen” or “progesterone” thrown around, but understanding what they do and how they work is a whole other level.
When it comes to fertility, hormones take on an even bigger role. They control everything from the timing of ovulation to the preparation of the uterus for pregnancy. Knowing more about your hormones doesn’t just help you understand your body better—it can also be a game-changer when you’re trying to grow your family. At Care Fertility, we’re here to break it all down for you, so let’s dive into the fascinating world of hormones and how they impact fertility.
What are hormones?
Hormones are your body’s chemical messengers. They’re made by glands in the endocrine system and travel through your bloodstream to different parts of your body. These little messengers regulate all sorts of essential functions, like your metabolism, growth, mood, and, of course, your reproductive system.
When it comes to fertility, hormones are in charge of the entire process. They control your menstrual cycle, trigger ovulation, and prepare your body for pregnancy. Understanding how they work can help you take control of your reproductive health and feel more informed about your journey to parenthood.
The Key Players: Hormones That Affect Fertility
Your reproductive system is like an orchestra, and hormones are the conductors ensuring everything works in harmony. Here are the key hormones you need to know about and the roles they play:
-
Follicle-Stimulating Hormone (FSH)
Think of FSH as the starter pistol for your menstrual cycle. It’s responsible for waking up your ovaries and encouraging the growth of follicles, which house your eggs. Without enough FSH, your ovaries can’t properly prepare eggs for ovulation. -
Luteinising Hormone (LH)
LH is the big event hormone—it triggers ovulation, which is when your ovary releases a mature egg. After ovulation, LH supports the development of the corpus luteum, a ruptured follicle that has released the egg and produces progesterone to help sustain a potential pregnancy. -
Oestrogen
Oestrogen is like your body’s multi-tasker. It regulates your menstrual cycle, helps thicken the lining of your uterus in preparation for implantation, and signals the release of LH at the right time for ovulation. -
Progesterone
If oestrogen is the multi-tasker, progesterone is the nurturer. After ovulation, it makes sure the uterine lining is nice and fluffy and cosy and ready for a fertilised egg to implant into. If pregnancy occurs, progesterone helps maintain a stable environment to support the early stages of development. If pregnancy does not occur, progesterone rapidly drops off and the uterine lining breaks down and starts period bleeding. -
Testosterone
Often thought of as a male hormone, you probably associate testosterone only with men, but it also plays an important role in women’s fertility. It supports libido and aids the development of ovarian follicles. In men, testosterone is essential for sperm production.
What happens when hormones are out of balance?
Hormones need to work in perfect harmony for your reproductive system to function properly. If something disrupts this balance, it can lead to fertility challenges.
Conditions like polycystic ovary syndrome (PCOS) and thyroid disorders can cause hormonal imbalances. Lifestyle factors such as stress, lack of sleep, alcohol and drug consumption, poor nutrition and body weight can also play a role. These imbalances might disrupt ovulation, affect egg quality, or make the uterine environment less receptive to implantation.
Effects on the Menstrual Cycle
When hormones are out of balance, they can have a significant impact on your menstrual cycle. An imbalance might stop your cycle entirely, make it irregular, prevent ovulation, or stop a mature, healthy egg from being produced. Any of these disruptions can make it much harder to conceive naturally or through assisted techniques like IVF or IUI.
Effects on Fertility
Hormonal imbalances may prevent ovulation, disrupt the timing of the menstrual cycle, or create a less-than-ideal environment for implantation and early pregnancy. For example, women with PCOS often have higher-than-normal levels of androgens (male hormones), which can interfere with ovulation.
Testing and monitoring hormones
Hormone testing is one of the most effective tools for understanding fertility issues and tailoring treatment to individual needs.
-
Timing matters
Hormone levels fluctuate throughout the menstrual cycle, so the timing of fertility tests is crucial. For example, FSH and LH levels are typically measured early in the cycle, while progesterone is assessed in the second half. By tracking these changes, we can pinpoint where any imbalances may lie.

Comprehensive testing
Our testing includes checks your AMH levels, as well as other factors like thyroid function, which can also influence fertility. With this information, we can create a personalised treatment plan designed to restore hormonal balance and maximise your chances of success.
Supporting your hormones and fertility
The good news is that there are ways to support your hormones and improve your fertility naturally:
- Prioritise nutrition: Eating a balanced diet with plenty of fruits, vegetables, and whole grains can help stabilise hormone levels.
- Manage stress: Techniques like mindfulness or yoga can reduce cortisol, a stress hormone that can interfere with reproduction.
- Get enough rest: Sleep is essential for hormonal health, so aim for 7–9 hours a night.
- Avoid harmful habits: Smoking, excessive alcohol, and too much caffeine can disrupt your hormonal balance.
