Fertility is the natural ability to conceive or to cause conception. This means that healthy sperm successfully reach a healthy egg, and the fertilized egg subsequently implants itself in the uterus.

Before this can happen, both male and female sex hormones coordinate a series of essential preparations.
Fertility in men and women depends on hormones called gonadotropins, as they regulate ovarian and testicular function:

• Follicle-stimulating hormone (FSH) — responsible for sexual maturation and reproduction, mediating the growth of eggs and generation of sperm; and
• Luteinizing hormone (LH) — induces ovulation and promotes testosterone in men.

Women also have other sex hormones with their distinct role in the menstrual cycle.

• Estrogen — produced by the ovaries during the maturation of the egg cell and helps to release the egg at the end of ovulation; and
• Progesterone — prepares the lining of the uterus for the implantation of the potential embryo.

In short, fertility relies on the right balance of hormones, each playing a key role in making conception possible.

To use this fertility by age calculator, you only need to follow these easy steps:

If you're trying to conceive, understanding your menstrual cycle is key. The average cycle lasts 28 days, with ovulation typically occurring around day 14. Your fertile window includes the day of ovulation, the 5 days leading up to it, and the day after. This is the ideal time in your menstrual cycle to conceive ⚤.

However, note that everyone is different, so it is important to track your menstrual cycle and note the days you are most fertile 🥚🗓️. There are several methods you can use for this aim:

1. Calendar method — track the dates of the beginning and end of your period to determine the length of your cycle (or use our period calculator and ovulation calculator).

2. Basal body temperature method — measure your temperature with a basal thermometer every morning before getting up, an increase of 0.5 °F (0.3 °C) means that ovulation began.

3. Ovulation predictor kits — identifies the presence of LH in urine, which indicates that ovulation arises within the next 24 hours.

4. Cervical mucus method — clear mucus, similar to egg whites, indicates that you are currently ovulating.

Remember that these tools help you figure out the days you are most fertile, so when you are most likely to get pregnant. That does not mean that you cannot get pregnant from intercourses on days outside the fertile window.

Every woman’s menstrual cycle is unique, and it can be influenced by factors such as stress, diet, and exercise, with some women being more sensitive to these factors than others. Additionally, sperm from intercourse before ovulation can still fertilize an egg after ovulation, as sperm can survive up to five days in the female reproductive tract.

According to the WHO, infertility is diagnosed when pregnancy has not occurred after 12 months or more of regular, unprotected sexual intercourse.

When it comes to female infertility, we can differentiate between primary and secondary infertility:

• Primary infertility — affects the physiology or cellular structure of the reproductive tract, e.g., premature ovarian failure (POF), polycystic ovary syndrome (PCOS), endometriosis, and leiomyoma.
• Secondary infertility — concerns other genetic defects that impact metabolism and hormones, such as fragile X syndrome, Kartagener's syndrome, myotonic dystrophy, etc.

The most common causes of infertility are ovulatory disorders, poor semen quality, and tubal disease. However, you may still struggle with infertility even if you don't have any of the aforementioned conditions. There are several factors that can affect your chances of getting pregnant.

A woman's age is the most important factor for fertility. Women are born with a set number of eggs, which gradually decrease over time. In younger women, the decline is slow, but it becomes much more rapid in their mid- to late 30s. At the same time, the quality of the eggs also gets worse, making it harder for older women to get pregnant and increasing the chance of miscarriage. Male fertility also decreases with age, though to a lesser degree and much later in age.

There are other factors linked to female fertility, such as:

• Genetic conditions — inherited disorders affecting your reproductive system;

• Lifestyle factors — healthy habits such as exercise and unhealthy ones such as smoking have a real impact on your fertility;

• Diet — consuming food rich in antioxidants is crucial for the health of eggs and sperm;

• Health conditions — disorders such as thyroid diseases or diabetes may complicate the process of getting pregnant;

• Environmental influences — there is also a link between different chemicals, such as pesticides and radiation and fertility;

• Medications — such as thyroid medication and steroids can interfere with your menstrual cycle.

As mentioned before, age plays a huge role in female fertility, as aging has an impact on the ovaries and eggs. If you're under 30, the chances of you conceiving within one year is 85%! This value drops to 75% by the age of 30, 66% at 35, and 44% at 40. You can see how this trend changes with this fertility rates by age graph:
