Can I Get Pregnant With 21Mm Follicle?

Last Updated on September 4, 2023 by Marjorie R. Rogers

Yes, it is possible to get pregnant with a 21mm follicle. A follicle is a fluid-filled sac that forms around the egg and helps protect it until it is ready for ovulation. During ovulation, the follicle ruptures and releases the egg into the fallopian tube where fertilization can take place if sperm are present.

It has been shown that larger follicles (15mm or greater) tend to release more mature eggs which can lead to higher fertility rates than smaller ones. However, even small follicles can still result in pregnancy so long as there are viable sperm waiting in the fallopian tubes at just the right time of ovulation.

  • Visit your doctor: The first step is to make an appointment with your doctor for a fertility evaluation
  • During this visit, your doctor will do a physical exam and discuss any medical history that may impact fertility
  • Your doctor can also recommend lifestyle changes or medications that could help you conceive
  • Monitor ovulation: It’s important to track when you are most fertile so that you can plan sexual activity accordingly
  • Many women use ovulation predictor kits (OPKs) to determine when they are at their most fertile point in the menstrual cycle
  • You should also chart your basal body temperature every day, as it rises slightly during ovulation and helps indicate when conception is possible
  • Have intercourse around the time of ovulation: Once you know when you are at your peak fertility, have unprotected sex during that time frame if possible — this increases the chances of conception due to increased sperm count and mobility near the end of each menstrual cycle
  • 4 Visit a specialist if necessary: If after trying naturally for six months without success, consider visiting a reproductive specialist who can check follicle size using transvaginal ultrasound (TVU)
  • An egg must reach 21mm before it is released from its follicle — having intercourse close to this time increases chances of fertilization since sperm lives inside of female bodies for up to five days after eja*culation!

21 Mm Follicle in Right Ovary

A 21 mm follicle in the right ovary is a large, fluid-filled sac that contains an immature egg. This size of follicle is typically found during the middle stages of a woman’s menstrual cycle, when hormones are released to stimulate the growth and maturation of eggs for potential fertilization. Having a 21 mm follicle can indicate that ovulation is likely to occur soon, making it an important marker for fertility and pregnancy planning.

Is 21Mm Follicle Good Pregnancy?

A follicle measuring 21mm is considered a good size for pregnancy, as it indicates that the egg within the follicle is mature and ready to be released. The optimal size of a mature follicular structure should measure between 18-24mm in diameter when an ovulation occurs, so 21mm falls right at the peak of ideal growth. In addition, having a larger than average sized follicle can actually increase your chances of conceiving successfully since it means there is more space available for successful fertilization.

Is 21 Mm Follicle Good for Ivf?

Yes, a 21 mm follicle can be an excellent size for IVF. It is considered to be a good size because it is large enough that the egg inside has matured and can be ready to be retrieved during an IVF cycle. In addition, research suggests that larger follicles are associated with higher success rates of embryo implantation.

Therefore, having a 21 mm follicle prior to retrieval likely increases your chances of achieving a successful pregnancy outcome.

What Should Be the Size of Follicle to Get Pregnant?

The size of the follicle needed for pregnancy varies from woman to woman and can range from 18-24 millimeters. The average follicle size is around 22 millimeters, which is considered optimal for successful ovulation and conception. During ovulation, a mature egg should be released from the largest dominant follicle in order to fertilize with sperm and create an embryo; if this does not occur, it can make it difficult for a pregnancy to occur.

Therefore, monitoring the size of your follicles throughout your cycle will help you determine when you are most likely to be able to conceive.

Can You Get Pregnant With a 20Mm Follicle?

Yes, it is possible to get pregnant with a 20mm follicle. A follicle of this size is considered to be at the optimal stage for releasing an egg and therefore conception can occur. It is important to note that ovulation must take place in order for pregnancy to be successful; however, if the 20mm follicle has already released or ruptured, then ovulation has likely occurred and there may be a higher chance of becoming pregnant.

Additionally, having a larger than average sized follicle can increase your chances of conceiving as these types of follicles tend produce more mature eggs which are more viable during fertilization.


In conclusion, a 21 mm follicle is large enough to release an egg and can result in pregnancy. However, it is important to remember that there are other factors involved in becoming pregnant, such as timing of ovulation and quality of the egg. Therefore, if you are trying to conceive with a 21mm follicle size, it’s best to consult your doctor about the best ways for you to optimize your chances for conception.
