Medications in Assisted Reproduction

The medication prescribed in a fertility treatment is usually a step during the period of ovarian stimulation or assisted reproduction.

And undergoing fertility treatment is not something that is usually very desirable. The process involves a lot of stress, both physical, emotional and also financial, so it is common to have doubts and some anxiety because it ends (well).

Much of success depends on proper preparation and precise timing. Although there are always things that we can contribute to create the best possible conditions (diet, exercise, stress control), there are other aspects that are beyond our control. 

One of these elements is medication for assisted reproduction. It is the clinics that are in charge of prescribing medications at all times. The feeling of not knowing, of depending on others, of being afraid of the unknown can cause women some discomfort. 

What am I taking? So that? Why do I have to prick myself? When how where? Will I be doing it right? Will it hurt? Will it have risks for my health? Will I be able to do it? What if I forget to take something? 

The importance of medication regimens in fertility treatments

Although for the woman who is undergoing fertility treatment this will be a very important part of her life (if not the most important thing at that moment), there are times when she may forget a dose, a dosage change, etc In some cases this is really important, in others not so much. 

Yes ok Protocols may differ slightly from one clinic to another, They have a lot in common. 

In this article we review the medications that are usually used during assisted fertility processes in a simple way without going into any case whether it is the appropriate treatment or not, this must be assessed by the healthcare professional, personalizing your treatment at all times. Here you will find a guide, not any recommendation.

Understanding always brings serenity. And that is something that you, as a woman, need right now. And if after reading this article you still have doubts, feel free to ask the professionals at the chosen clinic.

 

Types of ovarian stimulation protocols

Long or short protocols are nothing more than different treatment plans used to stimulate women's ovaries in order to obtain more eggs in a cycle than would be normal for a woman. Depending on the characteristics of each woman, the professional chooses a long or short protocol with the ultimate goal of collecting the greatest number of eggs and of the best quality possible.

Long protocol

The long protocol that, as its name indicates, extends further in time. For about four weeks, the woman will have to take certain medication that stimulates follicular maturation. This protocol begins in the cycle before the one in which the ovarian stimulation is going to be performed, that is, a period will come in between. 

Short protocol

This is the most commonly used protocol. As its name indicates, it is a protocol that lasts only a short time, which is why it is called short. In this case, the woman will start treatment after your period, about 3, 4 or 5 days as directed by the medical professional. 

Medication during assisted reproduction treatment

We are going to detail which medications are used, when and for what purpose, depending on the phases of assisted reproduction treatment you are in. 

Medication before starting stimulation. 

Examples: Buserelin, Cetrotide, Procrin, Orgalutran, Decapeptyl or Synarel.

Before explaining the medication for an in vitro fertilization (IVF) process, it must be taken into account that it will always be necessary to carry out a personalized study for each patient. 

The type of response depends on many factors that must be taken into account. In fact, using a similar protocol women may have a very different response. The woman's age, ovarian reserve, ovarian function, basal hormone levels, liver health, etc. determine the final response. 

For this reason, treatments are often accompanied by a directed cycle, that is, a specific medication to artificially but more accurately control the woman's reproductive functioning. 

Thus prevent spontaneous ovulations or ovulations that are too early than expected, which could complicate the process. 

For this effect there are two options: 

  • "Trick" the brain by taking synthetic hormones. These are similar to the hypothalamus hormones that regulate the release of other hormones to ovulate (GnRH hormone agonists). The brain understands that there are already enough of this type of hormones and stops producing its own. In this way, the ovary works exclusively with hormones that are supplied from the outside. This allows the woman's cycle to be controlled precisely. They can also be applied as a nasal spray.
  • Suppressing the peak of a certain hormone that is responsible for triggering ovulation (LH hormone). It is done with artificial hormones with a function opposite to the order given by the hypothalamus (GnRH antagonists). These antagonists can also be recommended at the end of the stimulation process, if there is a risk of the woman ovulating spontaneously.

The choice of using agonists or antagonists of the GhRH hormone depends on doctors and the decision is made based on the characteristics of each woman. The means of administering this mediation is usually through injections.

This process is called downward regulation and basically puts the body into a temporary menopause-like state. Although it is possible that there may be some side effects similar to those of menopause, it is for such a short period of time that sometimes it is not even noticeable. 

Once it is controlled when the woman ovulates, we move on to the next step: ovarian stimulation. 

 

Medication at the beginning of stimulation

Example: Gonal-f, Puregón and Fostipur or Menopur, Pergoveris and HMG Lepori.

Medications to perform stimulation must generally be kept cold, and are applied through injections. For each medication you will find the exact specifications, read them carefully and you will see that the entire process will be very easy for you. 

Chances are you've never had to get a shot before. Now, during treatment, you will have to do it daily for about 10-15 days. 

So, some clinics offer a little training on how to do it. It is not complicated, but it is delicate and something that sometimes costs a little.

The stimulation lasts about 12 days with daily injections. It is interesting that it is at the same time each day and in different areas of the body. 

It is mainly about the FSH hormone, which stimulates the follicles in the ovaries. The amount is usually very slight, the minimum for the general correct response of the average woman. Sometimes, in addition to FSH, the medication also contains the luteinizing hormone LH.

Do not be afraid. The doses of hormones are very mild… There are very few cases of women who have problems with this mediation. It is very likely that the most tedious side effects are related more to the injection than to the medication itself. 

Before finishing these days of ovarian stimulation, the clinic will check the growth of the follicles in the ovaries, as well as the correct formation of the endometrium. It is even possible that the treatment can be adapted a little depending on how you respond to the stimulation. 

At the end of the medication days you may feel some tightness in your lower abdomen, similar to the days before menstruation. But little more... If you have any questions, you already know that you can consult continuously with the team of experts who are managing your cycle. 

 

Medication 36 hours before egg collection

Examples: Ovitrelle, Gonasi, Pregnyl

When the ultrasound shows that the eggs are of the correct size, a new injection must be given. It is usually a day and a half before the ovarian puncture to finally extract the eggs stimulated in the previous stage. 

This is an injection with an extra dose of the hormone human chorionic gonadotropin (HcG) that helps the eggs mature. It helps the eggs enter a final stage of maturation and is ready for retrieval and fertilization through IVF. It is important not to forget this step at the time to be successful. in the collection of eggs and that they are mature. 

 

Medication after ovarian puncture

Examples: Utrogestan, Progeffik, Prolutex

It is not necessary to take any extra medication for ovarian puncture. However, during the follicular aspiration process, part of the cells that line the interior of the follicles (granulosa cells) are usually extracted. 

These are responsible for the production of progesterone, so an exogenous supply (from outside) of this is usually recommended so that there is no deficiency. 

Progesterone is known as the pregnancy hormone because it is responsible for maturing the endometrium, the place where the embryo implants. Progesterone is also responsible for maintaining an optimal uterine environment for the development and growth of the fetus until birth. 

The extracted eggs are taken to the laboratory to fertilize them and to keep them in cultivation and see how they evolve. 

Currently, it is usually waited for them to reach day 5 of development until the moment in which the fertilized embryos are transferred or cryopreserved. 

This is an important moment in the evolution of these cells. If they reach day 5 correctly, they are more resistant to withstand subsequent cryopreservation without being altered.  Progesterone can be applied in vaginal suppositories every few hours as instructed by the medical team, but injected progesterone is also usually used. The treatment usually lasts about 14 days until we know if the process has produced a positive result after the betawait. 

If there is finally a pregnancy, it is usually scheduled again in egg format until the embryo sac and the embryo with a heartbeat are visualized.

 

Medication for implantation

Examples of estradiol pills: Meriestra and Progynova; patches: Estradot, Evopad and Estraderm

To thicken the endometrium, estrogens can be prescribed in the form of a patch or pill.  Progesterone medication, along with estrogen, is also used if a patient undergoes a frozen embryo transfer or uses donor eggs to conceive.

 

Other medications

In addition to this basic medication, there are cases in which other medications are prescribed. We list some of them: 

  • Oral contraceptives. They can be used initially to help regulate and control the cycle.
  • Steroids (Medrol, Prednisone). It may be prescribed to help with any pre-existing inflammation and to prepare the uterus for implantation of an embryo.
  • Clomiphene citrate (Clomid). This medication is prescribed to help the pituitary gland secrete more follicle-stimulating hormone (FSH). It is prescribed orally for a maximum of six months.
  • Metformin. Metformin is not technically a fertility drug, but is used in the treatment of people with diabetes. However, it is used in women with polycystic ovaries who have problems ovulating correctly. Since abnormal insulin levels in the body alter ovulation. 
  • Euthyrox. There is some evidence that thyroid-stimulating hormone (TSH) should be below 2.5 mIU/L to promote the best fertility scenario. It is not that it is impossible to conceive with a less active thyroid, but it may mean some limitation in pregnancy options.

Apart from these, there may be many other medications that your biomedical team considers relevant in your specific case. In any case, these are very proven and safe protocols. 

Adapting the medication to each woman is something that the clinic you have chosen will do. Of course, we hope that with all this information, we help you be calmer and more confident in the process. Remember that this It is only an informative portal and you have to evaluate any medical information with your trusted specialists. All of these medications are personalized medical prescriptions.
