Evening Primrose Oil (EPO) – Its Role In Trying to Conceive

What is Evening Primrose oil or EPO?

Evening Primrose Oil is the oil derived from a North American wildflower called Evening Primrose. Evening Primrose is not really a primrose, but it gets its name from that flower because the plant looked similar to an English Primrose. The oil is rich in Vitamin E just like olives and nuts are. In addition, evening primrose oil also has gamma linolenic acid (GLA), an essential fatty acid. People that have difficulty creating in this fatty acid in their own bodies can benefit from its use.

The Europeans were one of the first to make it popular. They brought it back to their native soil and crowned this oil a “King’s cure-all” because of its many useful properties that can cure a large number of diseases. In England, the oil is approved for use with eczema and high cholesterol. In women, it can especially be helpful for relieving breast pain, menstrual pains and improving the quality and fertility of cervical mucus.

How does Evening Primrose Oil help you in getting pregnant?

Evening Primrose Oil or EPO lowers cholesterol, helps to alleviate premenstrual syndrome symptoms and aids in the production of fertile quality cervical fluid. Evening Primrose Oil or EPO does a world of good in treating aliments of all sorts. Evening Primrose Oil or EPO is an essential fatty acid that contains gamma linolenic acid (GLA). This gamma linolenic acid (GLA) is converted to a hormone-like substance called prostaglandin E1 which has anti-inflammatory properties and may also act as a blood thinner and blood vessel dilator. These anti-inflammatory properties of evening primrose oil help people suffering from pains, aches and cramps.

Evening Primrose Oil or EPO also has effects on premenstrual syndrome symptoms and cervical mucus. If you suffer from premenstrual syndrome, it could be because you are deficient in the fatty acid, gamma linolenic acid (GLA). Evening Primrose Oil or EPO can help your body to alleviate the premenstrual syndrome symptoms by replacing the gamma linolenic acid (GLA).

Evening Primrose Oil or EPO helps women to produce more fertile quality cervical fluid also known as “egg white cervical mucus”. This type of cervical fluid is fertile, thin, watery, clear and “stretchy” and easily aids the sperm to swim through the uterus and into the fallopian tube, and to the egg. Also, this type of fluid helps the sperm to stay alive for up to five days inside the fallopian tube, thus enabling conception to happen even if you don’t have intercourse again by the time ovulation occurs.

If your cervical fluid is thick, brown or dry, it can obstruct or prevent fertilization. Some women are very dry, and have problems in producing an adequate amount of fertile quality cervical fluid. Drinking a lot of water and taking the Evening Primrose Oil or EPO can certainly help in the production of fertile cervical fluid in these women.

What is the dosage for Evening Primrose Oil or EPO?

Evening Primrose Oil or EPO should only be taken from menstruation to ovulation. This is because Evening Primrose Oil or EPO can cause uterine contractions in pregnancy. The dosage taken should be 1500mg to 3000mg per day. Since essential fatty acids are necessary, you can take flax seed oil in place of Evening Primrose Oil or EPO after ovulation. This may be taken throughout pregnancy as well.

There are many remedies out there to help with fertility, but few are as good as Evening Primrose Oil or EPO. Evening Primrose Oil or EPO is excellent for women because of the help it gives in alleviating premenstrual syndrome symptoms, and even menopausal women can benefit from taking it. There are a large number of women who will vouch for Evening Primrose Oil or EPO as a great agent to increase the fertile type cervical fluid.

Like all herbs, the use of Evening Primrose Oil or EPO can take a month or two to build up, and produce the results you are looking for. It is essential that you chart your fertility symptoms and signs, so you can know when you have ovulated. By knowing this information, you can discontinue the Evening Primrose Oil or EPO after ovulation and start the flax seed oil. Unless you are very regular, charting your fertility signs is the best tool to determine where you are in your cycle.
