GnRH is released in pulses and not continuously. In men, these pulses come at a pretty consistent rate. In women, the frequency of the pulses varies depending on where the body is in the menstrual cycle. For example, just before ovulation , the GnRH pulses are more frequent. Gonadorelin is a medication that acts like the hormone GnRH in the body.

Testing usually involves receiving injections of this hormone at a specific interval. Then, at a specific time, injection of gonadorelin just below the skin into the fatty tissue. This procedure — injection followed by blood draw — will be continued. The results will then be analyzed in a lab.

The test may be done in children with delayed puberty or adults with suspected hormonal imbalances. Treatment With Gonadorelin via Lutrepulse Pump. Women who are not ovulating may be treated with gonadorelin via a Lutrepulse pump. This is done if a lack of GnRH is the cause for anovulation. Men who are not producing sperm may also be treated with a Lutrepulse pump.

The pump delivers a measured dose every 90 minutes over a period of weeks. After treatment starts, in women, it usually takes two to three weeks for ovulation to occur. After ovulation, treatment usually continues for another two weeks through the luteal phase. During IVF treatment , your fertility doctor needs to control the ovulatory cycle. Otherwise, the eggs can be ovulated too early. They would not be able to be retrieved and fertilized in the embryology lab if this occurred.

Both of the medications produce a temporary menopausal state. GnRH antagonists include:. GnRH agonists may also be used to treat endometriosis and fibroids. Extent of endometrial shedding during normal menstruation. Omidvar, S. Menstrual pattern among unmarried women from south India.
