Tracking the surge in luteinizing hormone levels can help people to plan intercourse and increase the chances of becoming pregnant.
Understanding what LH is, when levels of the hormone rise, and the relationship between this increase and fertility can be important for women trying to get pregnant.
There are several apothekegenerika.de ways to track monthly LH surges. In this article, we describe methods of tracking, how long surges last, and how to use them to increase the odds of pregnancy.
What does a surge in LH mean?
The LH surge signals that ovulation is about to start. Ovulation is the medical term for an ovary releasing a mature egg.
A gland in the brain, called the anterior pituitary gland, produces LH.
Levels of LH are low for most of the monthly menstrual cycle. However, around the middle of the cycle, when the developing egg reaches a certain size, LH levels surge to become very high.
A woman is most fertile around this time. People refer to this interval as the fertile window or fertile period.
If there are no complications affecting fertility, having sex several times within the fertile period may be enough to conceive.
There are multiple markers of ovulation, including:
- LH levels in the urine
- the number of days since the last menstrual period
- the consistency of the cervical mucus
The best ways to test for the LH surge are:
- getting a blood test from a doctor
- using a home test in an OPK
A person can buy an OPK without a prescription, from drug stores or online. Many brands are available.
A positive result means that a person has a high amount of LH in their system. LH levels drop after ovulation, so the tests only show positive results during fertile periods.
Because each kit is different, it is important to follow the instructions carefully. All tests are relatively simple to use.
However, there are a few disadvantages, and OPKs may not be the right choice for everyone.
For example:
- If a person has irregular cycles, testing can be difficult, expensive, frustrating, and unreliable.
- Women with polycystic ovary syndrome (PCOS) may experience persistently high LH levels, and tests may show positive results throughout their cycles.
- Women approaching menopause may also have elevated LH levels, which makes test results unreliable.
- Testing at the right time is essential. If a person tests too late in their cycle, they will miss the LH surge and have to wait until the next month.
- If it takes a long time to conceive, buying multiple OPKs can get expensive.
If OPKs are unlikely to be effective, a person can ask their doctor for a blood test. It may take a few tests to identify the fertile period and to pinpoint the time of ovulation.
A doctor can also identify the fertile period by examining the ovaries on a transvaginal ultrasound scan.
Takeaway
For women trying to get pregnant, it is important to track the window of fertility and the LH surge.
A person can figure out the timing of the LH surge with an OPK or by taking a blood test. A doctor can help to decide which method of tracking will be most effective.
