What Are The Advantages and Disadvantages of IVF?

Medically Reviewed by Dr. Silvana Chedid on August 31, 2026

In vitro fertilization can offer a realistic path to pregnancy for couples and individuals who have not been able to conceive on their own, and it typically involves a series of medical steps, a real investment of time, and some physical and emotional demands along the way. Weighing these advantages and disadvantages before starting treatment can help you set realistic expectations and decide whether IVF is the right next step for your family-building goals.

At Chedid Grieco, we have spent more than 30 years helping individuals and couples pursue parenthood through in vitro fertilization and other assisted reproduction treatments. You meet with our team in Miami to discuss your options and build a customized plan, and that same personalized care continues through every stage of your treatment.

What Is In Vitro Fertilization?

In vitro fertilization (IVF) is an assisted reproduction treatment in which an egg and sperm are fertilized in a laboratory setting, forming embryos that are cultured, evaluated, and then transferred to the uterus. It is one of the most commonly used assisted reproduction techniques, and it gives our team the ability to work with several variables in the fertilization process that natural conception does not allow.

IVF may be an option for people who have difficulty conceiving on their own, who carry a genetic condition that could be passed on to a child, or who are pursuing parenthood as a same-sex couple or individual. It is also commonly used for women with gynecological conditions that affect ovulation or the movement of eggs through the fallopian tubes, and for cases involving male factor infertility that affects sperm quality or production.

How the IVF Process Works

In vitro fertilization follows a defined sequence of steps, though some complementary techniques may be added depending on your specific treatment plan. Here is what to expect at each stage.

1. Ovarian Stimulation

Hormonal medications are used so the ovaries can develop multiple follicles, giving our team several mature eggs to work with, whereas natural ovulation typically releases only one egg per cycle. This stage generally lasts about ten to fourteen days and is closely monitored with bloodwork and ultrasound so your medication protocol can be adjusted as needed.

2. Egg Retrieval

Once follicles reach the appropriate size, a trigger medication is given to prepare the eggs for retrieval. Shortly before ovulation would naturally occur, our team retrieves the eggs using a fine needle to collect the fluid that contains them, a brief procedure performed under sedation.

3. Semen Collection and Preparation

A semen sample is provided on the same day as egg retrieval, then undergoes laboratory preparation to select the sperm best suited for fertilization. When a frozen or donor sample is used instead, this same preparation process still applies.

4. Fertilization of the Eggs

Fertilization typically takes place in the laboratory using intracytoplasmic sperm injection (ICSI), a technique introduced to Brazil by Dr. Silvana Chedid, in which a single sperm is selected under a microscope and injected directly into each mature egg.

5. Embryo Culture

Fertilized eggs are monitored in temperature-controlled incubators for up to seven days while they develop into embryos. During this time, our embryology team evaluates each embryo’s development to help identify the ones with the best potential for transfer.

6. Embryo Transfer

One or more embryos are then transferred into the uterus using a thin catheter, a brief procedure that does not require anesthesia. Embryos can be transferred fresh or after being frozen, and freezing does not reduce embryo quality or the likelihood of implantation.

Weighing the Advantages and Disadvantages of IVF

IVF is a well-established treatment, but deciding whether it is right for you means weighing what it offers against what it asks of you.

Advantages of IVF

IVF gives our team more control over the fertilization process than most other fertility treatments, and it offers several potential benefits, including:

• The ability to test embryos for certain genetic conditions before transfer, when this option fits your care plan
• A treatment pathway for same-sex couples, single parents by choice, and people using donor eggs or donor sperm
• The option to freeze remaining embryos for future use rather than starting the full process again
• A structured timeline with close monitoring at every stage, rather than the unpredictability of unassisted conception

Pregnancies conceived through IVF are generally carried and monitored much the same way as pregnancies conceived naturally, without an inherent increase in miscarriage or birth-defect risk from the IVF procedure itself. IVF can also be paired with egg freezing for patients who want to preserve eggs for future use while pursuing treatment now.

Disadvantages and Considerations of IVF

IVF also comes with trade-offs that are worth discussing candidly. The process asks for a real commitment of time: a conventional IVF cycle, from your first consultation through the initial pregnancy test, generally spans around six weeks, and this can extend further if additional treatment is needed to prepare your body beforehand.

Ovarian stimulation carries some risk of ovarian hyperstimulation syndrome (OHSS), a condition in which the ovaries respond strongly to fertility medication. Severe OHSS is uncommon, and our team monitors your hormone levels and follicle development closely throughout stimulation to help reduce this risk.

Sperm quality and quantity also affect outcomes. If a semen sample shows changes in count, movement, or shape, this can lower the likelihood of fertilization, which is one reason our team evaluates both partners as part of your treatment plan.

Success Factors, Cost, and Time to Consider

Several factors influence how a given IVF cycle may unfold, including age, ovarian reserve, the underlying cause of infertility, and how your body responds to stimulation medication. Because these factors vary so much from person to person, we build an individualized protocol rather than applying the same plan to every patient.

IVF also represents a greater financial and time investment than some other fertility treatments, and some people need more than one cycle to achieve a pregnancy. Discussing your specific health history with our team before you begin gives you a clearer, more realistic picture of what your particular treatment path may involve.

Multiple Births and Other Considerations

Because IVF can involve transferring more than one embryo, it carries a higher chance of multiple pregnancy, such as twins, compared with unassisted conception. Multiple pregnancies come with their own additional considerations, including a higher likelihood of preterm birth, which is one reason single embryo transfer is often recommended when your embryo quality and health history support it.

Emotional and physical demands are part of this process as well. Hormonal medications can affect mood and energy, and the appointments, monitoring, and waiting periods built into each cycle ask for patience. Many people find it helpful to build a support system, whether that is a partner, family member, or counselor, alongside the medical care our team provides.

Who May Benefit From IVF

IVF is commonly recommended for people with blocked or damaged fallopian tubes, ovulation disorders, or unexplained infertility, as well as those with male factor infertility affecting sperm count or function. It is also a path to parenthood for same-sex couples, single parents by choice, and anyone carrying a genetic condition they would like to avoid passing on to a child, often alongside preimplantation genetic testing.

As an LGBTQI+-supportive, female-led practice, we work with a wide range of family structures and pathways to parenthood, including treatment plans that incorporate donor eggs, donor sperm, or a gestational carrier when that is the right fit for your circumstances.

Why Choose Chedid Grieco for IVF Care

Dr. Silvana Chedid has more than 30 years of experience in reproductive medicine and introduced ICSI to Brazil, and our team has helped nearly 9,000 families grow through IVF and related treatments.
