The results of this scan as well as your blood test will allow a fertility specialist to assess your fertility and therefore your ability to conceive. In a normal menstrual cycle one follicle will grow containing one egg. The follicle will get bigger until it ruptures at ovulation which then releases the egg.
This is usually around 14 days after the beginning of your menstrual cycle. Usually, yes. In most cases follicles will release an egg. However, whether the egg is mature enough or is of good enough quality for fertilisation is another matter. However, more follicles do not necessarily guarantee successful fertilisation.
The quality of the eggs is key and many women with fewer follicles can still conceive successfully with IVF because of the quality of the eggs. The number of ovarian follicles a woman has does decline with age and so does the quality of her eggs.
The number of follicles present within your ovaries will tell a fertility specialist about the state of your fertility. This is because follicles contain immature eggs. These immature eggs develop and grow in size until the follicle they are held in is of optimum size, whereupon they are released ovulation. If you have lots of follicles, then you have the potential to release more eggs increasing the chance that one of those eggs will be healthy enough to result in a successful pregnancy.
Egg quality is determined by your age and also your lifestyle. Most of the decline with advancing age is due to increasing rates of chromosomal abnormalities in older eggs.
IVF success by antral count under 35 years old Antrals and IVF Success for Female Age Under 35 at Advanced Fertility Center of Chicago IVF live birth rates are reduced with low antral follicle counts Women with low antral counts give fewer eggs and have higher cycle cancellation rates The median antral follicle count in women under age 35 age was Antrals and IVF Success for Female Age at Advanced Fertility Center of Chicago Women 35 to 37 years old have slightly lower success than the younger women Slightly higher rates of cycle cancellation are also seen The median antral follicle count at age was 17 Age antral follicle counts and IVF success.
Antrals and IVF Success for Female Age at Advanced Fertility Center of Chicago Women age 41 to 42 have substantially lower success rates Having high antral counts improves success rates more at this age The median count at this age was only This is because success rates are very low when less than 3 mature follicles are present on ultrasound.
The level of response of the ovaries when the woman takes injectable FSH for stimulation is often predictive of the egg quantity and quality — and therefore, also the relative chances for success with infertility treatment. The level of response that we will get from ovarian stimulating drugs can be estimated in advance with antral follicle counts see above table. However, here are some guidelines.

Ovarian reserve, antral follicles and egg supply Testing egg supply and predicting response to ovarian stimulation Women are born with all the eggs they will ever have. What are Antral Follicles? Vaginal ultrasound is the best way to accurately assess and count these small structures. We tend to get a good number of eggs at retrieval in these cases. Pregnancy rates are higher than average. When there are few antral follicles, we tend to get a poor response with few mature follicles.
Cancellation of an IVF cycle is much more common when there is a low antral count. Pregnancy rates are lower overall in this group. The reduction in success rates is more pronounced in women over 35 years old. When the number of antral follicles is intermediate, the response is not as predictable. Pre-pubertal girls do not produce the gonadal hormones that are necessary for the second phase of development, so the many eggs that started to mature will simply wither away.
The large number of eggs that are used each month account for the steady decline in the female's total egg pool that occurs from birth to menopause. In post-pubertal females, the dominant egg continues to develop, relying on hormones for growth and stimulation.
When the egg becomes fully mature, the follicle surrounding the egg bursts, and releases a mature egg which travels through the fallopian tube toward the uterus. The egg is capable of being fertilized for a short period, about 48 hours. If the egg is not fertilized during this time, it will die, and in another week or so, a new cycle of egg maturation will begin. This cyclic process of development continues through out a female's life until most or all of the eggs are depleted. This is the period of life known as menopause.
