Thus, assuming ovulation is between Days , Day 21 is the middle of the luteal phase when the production of progesterone from the corpus luteum gland peaks in an ovulatory cycle and if there was then pregnancy, the HCG would prevent the corpus luteum from then dying and it would produce even more progesterone. If ovulation has occurred later than Days 12 — 16, then the progesterone check would be better done a few days later so as to strike the middle of the luteal phase.
Conversely, if ovulation has occurred earlier than Day 12, an earlier progesterone test at about Day 18 is required. Progesterone levels should be interpreted with respect to the number of days before the onset of the next period. What is FSH? What is E2? Why measure around Day 2? In vitro fertilization is a treatment for infertility, not a test. However, the IVF cycle details can give useful information about egg and embryo quality.
By careful examination of the eggs and embryos during in vitro culture we can get clues about why pregnancy has not occurred previously. For example, the eggs may demonstrate poor morphology, may have problems with maturation, with fertilization, or with proper cleavage, etc..

This page is about day 3 FSH and estradiol testing See ovarian reserve for more on egg quantity and quality issues and other ovarian reserve tests. What does FSH hormone do? What produces FSH hormone? If this happens in a woman under age 40, we call it premature ovarian failure or primary ovarian insufficiency Why do we measure the FSH level on day 3?
Some practical problems with the day 3 FSH test: The cut off values used to say that egg quantity is good, OK, or poor is laboratory dependent. For example, and FSH of 11 in one laboratory may reflect good ovarian reserve — whereas a level of 11 in another lab using a different assay may indicate diminished ovarian reserve. See below for more.
While an abnormal result high baseline FSH tends to be very predictive of low egg quantity, a normal result does not necessarily mean that the egg quantity is good. There are a significant number of women with normal FSH values that have a reduced egg supply. The lower egg supply is not being reflected in their FSH value. This is why doing antral follicle counts and AMH levels can be useful.
By doing multiple ovarian reserve tests, we are more likely to find an ovarian reserve problem if there is one. Expect a good response to ovarian stimulation. Response is between normal and somewhat reduced response varies widely.
Overall, a slightly reduced live birth rate. Expect a reduced response to stimulation and some reduction in embryo quality with IVF.
Reduced live birth rates on the average. Low live birth rates. Antral follicle count is an important variable. Very poor or no response to stimulation. More about egg quality, egg quantity and fertility problems Day 3 estradiol testing A blood estradiol level on day 3 we do it on any day between days 2 and 4 of the menstrual cycle is a way to potentially discover some of those women with a normal day 3 FSH that may in fact have decreased egg quantity and quality.
Karande Dr. Klipstein Dr. Puscheck Dr. Schedule an Appointment With Us. Vishvanath Karande Oct 19 Comments. It is generally accepted that as a woman ages, her ability to reproduce will diminish and she will begin having trouble getting pregnant. Some women progress through menopause in their early thirties, while others conceive readily at age A basal cycle day 2 — 4 follicle stimulating hormone FSH level is a useful screening test of ovarian reserve.
Follicle stimulating hormone is the hormone released by the pituitary gland in the brain to stimulate the ovary to produce an egg. If the egg quality is compromised, the negative feedback signals are weak and there is a rise in the FSH level. Ovarian reserve screening is generally done on day 2, 3 or 4 of the menstrual cycle. Anti-mullaerian hormone levels are also routinely used details in another blog , Ultrasound measurement of ovarian volume and antral follicle count, patient's age and weight body mass Index, BMI is discussed in another blog are combined to assess ovarian reserve.
FSH is released in a pulsatile manner by the pituitary.
