Day 21 Fertility Testing

What Is Day 21 Fertility Testing And Why Is It Important?

Unless you have a comprehensive fertility workup, your journey towards parenthood won’t reach the success level you are hoping for. Such assessments will include not just blood work but some other tests, presented at multiple points within the menstrual cycle. Among the lot, Day 21 Fertility Testing is of primary importance. It forms a major part of evaluating your hormone levels to ensure that your body is all set for that healthy pregnancy.

Reasons behind fertility testing:

After trying to conceive naturally, you would always think of a fertility specialist to take help from. During such instances, the doctor’s priority is to paint a perfect picture of what you might need for procuring treatment success.

  • As part of the testing process, the endocrinologist will take some basic routine tests like SHG and HSG. The main goal is to determine the health of your fallopian tubes and uterus.
  • Most of these tests will get performed at any particular point within your menstrual cycle. One such test is targeted as Day 21 test.

More on Day 21 fertility test:

Day 21 is one major day to evaluate various processes, mainly for those with trouble conceiving. Through this evaluation process, our doctors will check the level of some chosen hormones like estradiol and progesterone. These are done through blood work and after measuring the thickness of the uterine lining.

For a woman with a 28-day cycle, it will take around 14 days to develop one follicle and ovulate oocyte. Then it will take another 14 days of the luteal phase, which will end up with the PMS on the 28th day of the cycle. So, here, day 21 will fall right in the middle of the luteal phase.

For women with frequent menses, the follicular phase remains a lot shorter. On the other hand, with a longer cycle, the follicular phase is longer. The luteal phase mostly remains more predictable than the follicular phase.

Some women get menses once every 2 to 3 months or it never comes at all. They might have to take oral contraceptives for regulating the period. For them, day 21 testing seems to be an important deal.

Day 21 testing for those suffering from irregular periods:

Day 21 testing won’t make any sense for those people who typically do not have 28-day cycles. The variability is mainly because of the follicular phase. It means the time it takes for a dominant follicle to grow and develop to ovulate is always shorter or longer, based on the individual.

Even though the follicle phase is subject to vary, the luteal phase will always take 14 days. The main progesterone day will be 7 days after ovulation and seven days before the next period starts.

In case you have longer cycles of 35 days, then you will ovulate around day 21 and the main progesterone level will be around day 28. On the other hand, if your period is less than the usual 25 days, then the major progesterone level will be around day 18.

The importance of Day 21 testing:
