Preferred Fertility Concierge
When undergoing fertility treatments like In Vitro Fertilization (IVF) or egg freezing, it's important to understand the medications involved in the process. At Preferred Fertility Concierge, we believe that education is empowering, and we’re here to guide you every step of the way. Below is an overview of the most common fertility medications, how they work, and their role in treatment.The first step in IVF and egg-freezing treatments is to stimulate the ovaries to produce multiple eggs. In a natural cycle, only one egg is typically matured and released, but in fertility treatments, the goal is to develop multiple eggs for retrieval.Ovarian Stimulation Medications
Oral Medications Used in Fertility Treatments
In addition to the injectable medications commonly used in fertility treatments, there are also several oral medications that play a crucial role. These medications are available for certain fertility issues, typically related to ovulation. Additionally, they can be used alone or in combination with injectable medications for timed intercourse, medicated IUI cycles and IVF
What is Clomid?
Clomid is an oral medication classified as a selective estrogen receptor modulator (SERM). It was initially developed to help women who struggle to ovulate regularly by stimulating their ovaries to produce eggs. Clomid is widely recognized and has a long-standing track record for its effectiveness and relative safety.
How Does Clomid Work for Fertility?
Clomid works by affecting the hormonal signals within the brain that regulate ovulation. Specifically, it tricks the body into thinking estrogen levels are lower than they actually are, prompting the pituitary gland to release more follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones stimulate the ovaries to grow and mature follicles, eventually leading to ovulation.
Common Uses of Clomid
Clomid is typically used for women with ovulation issues, sometimes in conjunction with intrauterine insemination (IUI).
Clomid is primarily prescribed to women with ovulatory disorders, such as:
Polycystic ovary syndrome (PCOS): Many women with PCOS don’t ovulate regularly, and Clomid can help regulate this process.
Unexplained infertility: Clomid is often a first-line treatment for couples with no identifiable cause of infertility.
Luteal phase defect: Some women may have difficulty with the luteal phase, which is crucial for maintaining early pregnancy. Clomid may help by supporting ovulation and hormone balance.
Hot flashes: A common side effect due to the way Clomid interacts with estrogen levels.
Mood swings: The hormonal changes can lead to irritability, anxiety, or mood swings.
Headaches and dizziness: Some women report mild headaches or dizziness.
Breast tenderness: Similar to other hormonal treatments, Clomid can cause breast sensitivity or tenderness.
Ovarian enlargement: In some cases, Clomid may cause the ovaries to enlarge, which can be uncomfortable.
Visual disturbances: Although rare, Clomid can cause visual symptoms like blurring or seeing spots. If these occur, a doctor should be informed immediately.
Clomid is typically taken orally for a short course at the beginning of a woman’s menstrual cycle, usually starting on days 3, 4, or 5 of the cycle and continuing for 5 days. The starting dose is generally 50 mg daily, though some cases may require an increase in dosage depending on the patient’s response. Ovulation generally occurs about 5 to 10 days after the last dose of Clomid, making this timeframe ideal for trying to conceive.
Key Benefits of Clomid
Non-invasive and convenient: Clomid is taken orally, which makes it a less invasive fertility treatment option than injectables or other interventions.
Highly effective for ovulation induction: It’s been shown to help 70-80% of women with ovulatory issues to ovulate.
Cost-effective: Compared to other fertility treatments, Clomid is often more affordable, making it an accessible first-line treatment for many individuals or couples.
Compatibility with other treatments: Clomid can be used alongside other fertility treatments, such as intrauterine insemination (IUI), to improve the chances of conception.
Clomid is often the first step in fertility treatment, offering a proven, accessible, and manageable option to support ovulation and increase pregnancy potential. It’s important for individuals to work closely with their healthcare provider to monitor their response to the medication and adjust the treatment as necessary.
What is Letrozole?
Letrozole, commonly known by its brand name Femara, is an oral medication initially developed to treat certain types of breast cancer. However, it has become widely used in fertility treatments as an ovulation induction agent. Letrozole is classified as an aromatase inhibitor, which works by lowering estrogen levels in the body, encouraging the ovaries to release eggs.
How Does Letrozole Work for Fertility?
Letrozole works by suppressing estrogen production, which signals the brain to produce more follicle-stimulating hormone (FSH). The increased FSH levels stimulate the ovaries to produce more egg-containing follicles. This helps women who are having difficulty ovulating on their own or those who need a more controlled ovulation process for treatments like intrauterine insemination (IUI) or timed intercourse.
Common Uses:
Ovulation induction: Letrozole is commonly prescribed to women with conditions like polycystic ovary syndrome (PCOS) who have trouble ovulating on their own, although they typically have an abundance of follicles.
IUI: It is frequently used in combination with IUI to ensure the release of eggs at the optimal time.
Unexplained infertility: Letrozole is often recommended as a first-line treatment for women with unexplained infertility, as it can help stimulate ovulation more effectively.
Letrozole is taken as an oral pill, typically starting on days 3, 4, or 5 of your menstrual cycle and continuing for 5 days. Your doctor will monitor your ovulation through blood tests or ultrasound to determine the optimal time of your fertile window and trying to conceive.
Potential Side Effects:
Most women tolerate Letrozole well, and the side effects are generally mild. It’s less likely than other fertility medications (like Clomid) to cause multiple pregnancies (twins or more), but the possibility still exists
Key Benefits:
During ovarian stimulation, there’s a risk of releasing eggs too early. These medications help control the timing of ovulation and preventing the growing follicles from being released too soon.
GnRH Agonists:
Medication: Lupron
How it worsk: This medication prevents the body from releasing eggs prematurely by suppressing the natural LH surge. They are often used in a “long protocol” before starting stimulation.
Common use: IVF and egg-freezing cycles.
Medications: Ganirelix, Cetrotide
How they work: These injections are administered later in the stimulation cycle to block the release of luteinizing hormone (LH) and prevent ovulation from occurring too soon.
Ovulation Trigger Medications
Once your follicles have matured, an ovulation trigger is used to ensure that the eggs are ready for retrieval.
Medications: Ovidrel, Novarel, Pregnyl
How they work: These injections mimic the body’s natural LH surge, which signals the ovaries to release the mature eggs about 36-40 hours before egg retrieval.
Common use: IVF, IUI, egg freezing, and timed intercourse.
GnRH Agonist Trigger:
Medications: Lupron (also used to prevent premature ovulation)
How it works: In some cases, a GnRH agonist like Lupron can be used as a trigger alone or in conjunction with hCG, especially in women at risk of ovarian hyperstimulation syndrome (OHSS).
Progesterone Support
After egg retrieval or ovulation, progesterone is needed to support the uterine lining and prepare it for embryo implantation.
Medications: Endometrin, Crinone, Progesterone in oil (PIO)
How they work: Progesterone supplements help thicken and stabilize the uterine lining, making it more receptive to an embryo for implantation.
These medications can be administered vaginally or through intramuscular (IM) injection. Supplemenatation is typically for an extended period of up to ten to twelve weeks of pregnancy.
Common use: IVF, IUI, or other fertility treatments requiring luteal phase support.
In some cases, additional medications may be prescribed to optimize the success of fertility treatment.
Estradiol (Estrogen):
Medications: Estrace, Vivelle patches
How it works: Estrogen helps to thicken the uterine lining and support the overall hormone balance, especially in frozen embryo transfer cycles.
Common use: Frozen embryo transfers, preparing the uterus for implantation.
Dexamethasone or Prednisone:
How they work: These steroids may be prescribed to suppress the immune system slightly, reducing inflammation that could interfere with embryo implantation.
Common use: Sometimes used in IVF cycles, particularly for patients with immune issues.
Blood Thinners (Heparin, Lovenox, Aspirin):
How they work: These medications are sometimes prescribed to improve blood flow to the uterus and reduce the risk of blood clotting, which can negatively affect implantation.
Common use: Used in cases where there are clotting disorders or recurrent pregnancy loss.
