Infertility investigations for women
Progesterone levels increase after ovulation, reaching a maximum level seven days before the start of the next period. The progesterone test is used to test whether a woman is ovulating (releasing an egg). In a regular 28 day cycle, the progesterone test is taken on day 21 of a woman s cycle. If a woman s cycle is longer or
TIMING THE FERTILE PERIOD OF THE BITCH: BRIEF REVIEW
Progesterone levels are baseline prior to the LH surge; increase to 1.5 to 2.0 around the time of the LH surge and increase to >5 ng/ml by the peak fertile and often are >10 to 15 ng/ml by the end of the fertile period. The time of the LH surge can be closely estimated from the initial rise in progesterone levels. Accuracy is related to the testing interval.

In the days just before ovulation, this dominant follicle secretes increasing amounts of estradiol so that the reproductive tract is receptive to sperm and also elicits a surge of luteinizing hormone (LH) from the pituitary gland. The LH surge initiates ovulation: maturation of the oocyte, release of the egg, and luteinization.

The beginning progesterone levels are typically less than 1.0 ng/ml until the day before the LH surge. The day of the LH spike, serum progesterone concentrations are 2-3 ng/ml; the day following the LH surge, the serum progesterone concentration is 3-4 ng/ml. Ovulation occurs at a progesterone level of 5 ng/ml. Figure 2.

luteinizing hormone (LH) that occurs just before you ovulate. The LH surge stimulates one of the ovaries to release an egg and produce progesterone.

A mid-luteal phase serum progesterone level, obtained approximately one week before the expected menses (e.g., day 21 of a 28-d cycle). A progesterone level >3 ng/mL is evidence of ovulation. If the progesterone concentration is <3 ng/mL, the patient is evaluated for causes of anovulation (serum prolactin, TSH, FSH, and assessment for polycystic ovary syndrome).
