Letrozole is the generic name of a currently tested research liquid called Femara. Scientific studies have been conducted on animal test subjects to determine whether this research liquid can be used to treat ovulation issues and unexplained infertility in different test subjects. Letrozole is a research liquid that is classified as an aromatase inhibitor. This research liquid has also been used in animal test subject studies for the treatment of cancer in breast tissue.
How Letrozole is used for Fertility
When animal test subjects are exposed to this research liquid, it has shown to inhibit the enzyme aromatase, which then causes estrogen levels to be suppressed. Studies on animal test subjects have shown to causes the brain and pituitary gland to release larger amounts of follicle stimulating hormones, or FSH. Animal test subjects that had polycystic ovary syndrome or anovulation (issues with ovulating), the FSH increase causes a mature follicle to develop within the ovary and cause egg ovulation. In the medical world, this is known as “induction of ovulation”.
Letrozole is also being studied on animal test subjects that are already able to ovulate, but are still having problems getting pregnant. When researched, Letrozole has shown to causes the development of multiple follicles, which results in multiple eggs being released. Scientific studies on animal test subjects indicate this may help to increase chances of animal test subjects from becoming pregnant during a natural menstrual cycle. The scientific term for the process of multiple eggs and follicles being produced is controlled ovarian hyper stimulation or superovulation.
Clomid Vs. Letrozole
Clomid, also known as clomiphene citrate, is another research liquid that is being studied with animal test subjects to help stimulate ovulation when it can’t be done naturally on their own. Some of the animal test subject concluded that Clomid didn’t work for researched Letrozole and received favorable results. The following results were determined:
- Some of the test results who didn’t respond to Clomid had their ovulation induced when Letrozole was used.
- Some of the animal test subjects that used Clomid and never got pregnant used Famara and conceived.
- Unpleasant side effects results in some of the test subjects that used Clomid, making Famara more favorable for them.
Success Rate of Famara-Letrozole
The chances of test subjects becoming pregnant with Famara are pretty much the same as if they used Clomid. This all comes down to the age of the test subject, sperm quality and status of the fallopian tubes.
A higher success rate was found in test subjects that weren’t able to ovulate on their own. The following conditions improve the success rate of test subjects by 15% per month:
- No other problems with fertility are found in the animal test subjects
- The test subject is younger than half of their natural life cycle.
The lowest success rate was in animal test subjects that had unexplained infertility problems, but still ovulate on their own.
Other Uses for Letrozole
This research liquid has also been used on postmenopausal animal test subjects who have had surgery for hormone receptor-positive early breast cancer and advanced breast cancer. It has also been tested on subjects that have received five years of tamoxifen therapy. Research has been done on animal test subjects that are in menopause (natural or artificially induced) who have cancer that’s spread from their breast to other areas of the body, and have already had anti-estrogen therapy.
Letrozole is being tested in breast cancer animal test subjects because it inactivates an enzyme called aromatase, which prevents estrogen production. Estrogen is a known source for cancer cell growth.
