In a normal cycle, a surge of LH triggers ovulation and release of the egg s. The body responds to hCG in the same manner as it does LH that is, they have the same biological effect , so a surge of hCG can also be used to trigger ovulation. When using antagonist to prevent ovulation, either hCG or Decapeptyl can be used to trigger ovulation.
By using these hCG drugs we can time ovulation precisely and can collect eggs approximately 36 hours after the hCG injection before they are released by the ovary. Store in original box and refrigerate at temperature between degrees. Do not freeze and protect from light. Product has a shelf life of 3 years and should not be used after the expiry date. Progesterone is normally produced by the ovaries in the second half of the menstrual cycle and during the first weeks of a pregnancy.
Progesterone may be prescribed after your embryo transfer to ensure the lining of the uterus is optimal for implantation. We also prescribe progesterone in combination with oestrogen tablets when you are using frozen embryos or donor eggs. In these cases, if you become pregnant, you need to continue progesterone for approximately 8 weeks after the pregnancy test. Progesterone pessaries or Crinone are administered vaginally because this achieves the most effective absorption of the drug.
Note: If you are taking progesterone it may prevent a period but this does not necessarily mean you are pregnant. Pessaries can cause vaginal and labial irritation and soreness. As the pessaries melt, a small amount will discharge vaginally. You can use a panty liner to protect underwear.
In rare cases you could be allergic to these substances. Progesterone pessaries should be refrigerated to maintain their effectiveness. Crinone does not require refrigeration. Progynova is a synthetic oestrogen replacement. It is used to build up the lining of the uterus to prepare for embryo transfer during a frozen embryo transfer cycle. Progynova is usually taken daily starting on day 1 of the menstrual cycle. We will give you dosage instruction before you start your cycle.
The medication is taken until the day of your pregnancy test and, if the test confirms you are pregnant, you should continue to take the tablets for another six weeks. If the test is negative, you can stop the tablets and a period will start within a few days. Side effects are uncommon, but breast tenderness, gastric upset, nausea, headaches and an increase in weight have been reported.
The friendly and professional team at Life Fertility Clinic are happy to answer any other questions you may have about medications used in fertility treatment. This fact sheet provides an overview of the medications that may be prescribed during fertility or IVF treatment, including an explanation of how and why they are used and some of the potential side effects. Administration These agents are taken orally, usually on days of the menstrual cycle and work by sending a message to the pituitary gland, telling it that it needs to start secreting, or to secrete more, follicle stimulating hormone FSH.
Your specialist or Nurse Coordinator will advise you on your particular dose and timing. Side effects of anti-oestrogens Normally any side effects of anti-oestrogens are mild. Administration GnRH drugs are usually prescribed in combination with ovulation stimulation medications.
