Luteinizing hormone (LH) is one of the hormones produced by the pituitary gland. Generally, it secretes at very low levels throughout your menstrual cycle.
Once a developing egg follicle reaches a certain size usually around the midpoint of your cycle Luteinizing hormone (LH) secretion surges to high levels. This hormone surge triggers ovulation about 24 to 36 hours later.
Ovulation is when a mature egg is released from the ovary. It’s the beginning of your fertile period. After the egg is discharged, the follicle on the ovary is converted to a structure known as the corpus luteum. It then begins to secrete progesterone. Progesterone is a hormone supports a potential pregnancy.
If pregnancy doesn’t occur, the corpus luteum dries up, stopping the secretion of progesterone, and triggering the start of a menstrual period.
Important of luteinizing Hormone (LH)
Your luteinizing hormone (LH) surge is important because it starts the beginning of ovulation and your fertile period. This is the best time for you to begin having sex without using a condom.
Once the egg is discharged, it’s only viable for about 24 hours. After that, your fertile window is over. This makes it very necessary to be able to identify the best time to conceive.
