LH and FSH peak to their highest levels during the middle of the menstrual cycle, around day 14, which is known as ovulation.
FSH typically peaks around day 14 of a regular 28-day menstrual cycle, which is around the time of ovulation. This peak is responsible for triggering the release of the mature egg from the ovary.
Follicle to release a mature egg
The luteinizing hormone (LH) reaches its peak concentration around the middle of the menstrual cycle, approximately 24-48 hours before ovulation. This surge in LH triggers the release of the mature egg from the ovary.

To calculate concentration from peak area in HPLC analysis, you can use the formula: Concentration Peak Area / (Slope x Injection Volume). The peak area is obtained from the chromatogram, the slope is the calibration curve slope, and the injection volume is the volume of the sample injected into the HPLC system.
One of the functions of FSH in the menstrual cycle is for development of the primary follicle during the first few days of the menstrual cycle, and there is a small peak of this hormone between approximately days 1-6. As oestrogen levels increase (oestrogen is secreted by the theca interna of the secondary oocyte) this feeds back negatively, thus decreasing the level of FSH until approximately day 12. Oestrogen levels reach a peak between days 11 and 12, and then start to decline. As levels of oestrogen decline, FSH levels start to increase once more, and there is a small peak of FSH on day 14 when ovulation occurs. FSH is responsible also for the choice of the dominant follicle; a woman has many follicles, but only one (or 2 if there are dizygotic twins) will mature. This appears to depend on the number of FSH recpetors on the surface of the follicle, i.e the follicle that has most receptors will be the one which matures. To answer your question, then, I would say that the 2 main functions of FSH in the menstrual cycle are: 1) The initiation of follicular development, and general development of the primary follicle 2) Choice of the dominant follicle, i.e the follicle which will be ovulated. I hope that helps: I am currently trying to answer the same question, and struggled to find a second function of FSH other than the initiation of follicular development!
