cetrotide injection

For any organism to get into the best condition of ripening or maturation, it must first be subjected to full growth and development. Imagine a fruit picked from the tree prior complete development, if put on a shelf, the fruit may ripen (mature) while on the shelf. Interestingly, it will look enticing as though it had gone through proper growth and maturation; truth be told, the fruit will be of poor quality when compared to a fruit which matured before it was plucked from the tree. This implies that if you want to eat a good quality fruit, one has to be patient for the fruit to grow and mature on the tree and only pick it once it has ripened; these principles are applicable to the development and maturation of a woman’s eggs. Continue reading for a clear understanding.


The Use of Cetrotide in Ovarian Stimulation


Human eggs have to be given adequate time to grow to maturity. A good quality egg means it’s viable for fertilization resulting in a healthy embryo. Ovarian stimulation protocols are directed towards follicle and egg development. A strategic individualized approach for controlled ovarian stimulation is crucial and the timing when it comes to giving fertility medication. Since the premature release of the eggs can occur while on fertility treatment, this injection is used to prevent this.


What is Cetrotide?


It is a man-made hormone and belongs to the class of medicine known as GnRH antagonists or simply antagonists. It is a newer medication, though it has gained popularity as it’s easy to use and effective. Cetrotide is used to regulate luteinizing hormone. Women with PCOS may have elevated levels of LH and may lead to the release of an egg before maturity; therefore, the doctor may prescribe the Cetrotide drug to delay LH surges on ovulation if one is undergoing assisted reproductive technology, like IVF. The medication is available in the form of a powder for a solution containing 0.25 Cetrorelix as the active ingredient and it is administered by injection.


Ovarian stimulation is an important stage in IVF fertility treatment. During Cetrotide IVF protocol other drugs may be used such as HCG and FSH with an aim of collecting many mature eggs from the ovaries. Ovarian stimulation is a complex process and in vitro fertilization cycle may be stressful, especially if one is going through it for the first time. To relieve the stress, request the fertility specialist, to elaborate the stages of IVF and the medications to be used in different stages. If the fertility expert has given a patient the chance to self-administer Cetrotide injection, the patient must follow his guidelines; if uncertain, give the doctor a call to confirm. Cetrotide 0.25 mg is taken once per day. It’s started on the fifth or the sixth day of stimulation and the use may continue for a number of days as guided by the fertility specialist. Ovarian stimulation may take 8 to 14 days, to trigger the ovaries to produce several mature eggs. Nonetheless, the stimulation period may take longer if the follicles mature slowly.

The following are some potential side effects linked to ovarian stimulation or Cetrotide side effects:


  • High chances of multiple births because of many eggs 
  • An increased risk of a miscarriage or premature delivery

In Conclusion


Finally, before ovarian stimulation is started, a woman’s ovarian reserve is determined; an ovarian reserve is the number of eggs available in a woman’s ovaries. It is done to predict the best protocol of ovarian stimulation that would yield quality eggs and follicles as well. Once the selection of the protocol is done, the fertility specialist chooses the ideal Cetrotide IVF protocol. If a woman will need to go through repeated cycles, the doctor will put her in a resting cycle for at least one month. During the resting period, between in vitro fertilization, the ovaries will recover awaiting the next stimulation. Fertility medication requires financial commitments, thus Cetrotide cost will vary from one pharmacy to another. Your fertility doctor may have been in the field for a considerable length of time, he can refer you to the best pharmacy to buy Cetrotide.
