When your husband comes home! The LH pic is 24 hrs before ovulation but you might test once a day... so you do not know when your LH peak started... it might have started 20 hrs ago ! Sperm lives 3 days... have them there rather early. Philippe
a surge of testosterone in males and it causes ovulation in females.
LH - leuteinizing hormone
Ovulation
The stick may have been defective or used incorrectly.
Ovulation happens roughly 36-40 hours after the HCG shot. A little sooner if you were already starting your LH surge.
The ovulation takes place due to surge of luteinizing hormone. This hormone comes from the anterior lobe of the pituitary gland.
if LH is up you are ovulating and progesterone should lower down.
A Lh surge (known as the luteal surge) indicates ovulation, not pregnancy. The luteal surge causes the follicle to burst which releases the egg into the body cavity, it is then drawn into the fallopian tubule where fertilization occurs. An increase in HCG indicates pregnancy, HCG in blood and urine is the first outward sign of pregnancy.
positive feedback of estradiol that increases the release of LH
However, the anterior pituitary gland will secrete larger quantities of LH (lutenizing hormone). This is actually the hormone that initiates ovulation. Then the rest of the hormones come into play.
The anterior pituitary gland releases luteinizing hormone (LH) about the time of ovulation. LH surge triggers the release of mature eggs from the ovary and stimulates the production of progesterone in the ovary.
You should replace the surge strip if the circuit breaker fails to reset.
