Human egg cells cannot move on their own. Instead, finger-like projections draw the oocyte towards and into the fallopian tube. Once inside the fallopian tube, small hair-like projections known as cilia continue to draw the ootid along. In the fallopian tube, if pregnancy occurs, the ootid is fertilized by a sperm cell. Once this fertilization takes place, the ootid goes through its final stage of maturation and becomes an ovum, a fully mature human egg cell.
During fertilization, the ovum and sperm cell combine, each containing 23 chromosomes each. Rather quickly but not at the exact moment of fertilization , these chromosomes fuse together, creating a new cell with a full set of chromosomes. This new cell is called a zygote. The zygote will develop into an embryo and, about nine months later, a newborn baby.

Menopause usually occurs between the ages of 45 and 55 — in the UK, an average woman reaches her menopause at the age of 51, however, 1 in women can experience the menopause before they reach 40 — this is known as premature menopause or premature ovarian insufficiency. There are ways to measure the egg count: an antral follicle count or an AMH test. The antral follicle count is a test that measures your ovarian reserve, performed in the early phase of your menstrual cycle, in which a doctor uses ultrasound to count the visible follicles in your ovaries.
Read more about what is AMH here. As the quality and quantity of the eggs decreases with time, egg freezing is a great solution for women to preserve their youthful and healthy eggs and increase the chances of conceiving later in life. The process of egg freezing involves the ovarian stimulation with hormones to produce multiple eggs, which are retrieved and stored in the laboratory in sub-zero temperatures.
Learn more about egg freezing here. At The Evewell, we deeply care about all of our patients and their loved ones. If you are considering having an AMH test or a Fertility treatment, please get in touch with us to see how we can help. We can arrange a consultation with one of our specialist doctors to guide you through the process or refer you to our fertility counsellor for support.
This test gives an idea of not only total egg count, but also of how many eggs a woman might be able to freeze during one cycle. AMH, on the other hand, is a protein hormone produced by special cells inside the follicles. Because AMH levels stay basically stable throughout a cycle, the blood test can be performed at any time. A typical AMH level for a fertile woman is 1. Or contact us to chat with a fertility advisor.
