For many individuals and couples, the path to parenthood involves more than timing and hope. When conception does not happen naturally, the reasons are often complex, and the decisions about what to do next can feel overwhelming. Intrauterine insemination (IUI) is a widely used, minimally invasive fertility treatment that places washed, concentrated sperm directly into the uterus during the ovulation window, bypassing common barriers to fertilization and meaningfully improving the chances of pregnancy. For those exploring their options, IUI is frequently recommended as a first step before advancing to more involved assisted reproduction procedures.
At Chedid Grieco, we understand the physical and emotional weight of fertility challenges, and we are committed to providing thoughtful, individualized care at every stage. Our female-led clinic has helped bring nearly 9,000 babies into the world over more than 30 years of practice. We hold both an FDA license and a New York tissue license, making us one of only eight clinics outside the U.S. to carry this distinction. Consultations are held in Miami, FL, while treatments are performed at our state-of-the-art facility in Brazil. Our team conducts a thorough evaluation before any treatment, including ovarian reserve testing and hormonal assessment, to determine whether IUI is the right fit for you.
What Is Intrauterine Insemination?
Intrauterine insemination is a fertility procedure in which a semen sample is laboratory-processed to concentrate the most motile sperm, which are then delivered directly into the uterus through a thin, flexible catheter. This bypasses the cervix and positions the sperm closer to the egg at the time of ovulation, increasing the likelihood of successful fertilization. According to the American Society for Reproductive Medicine, IUI is often considered first-line treatment for couples with unexplained or mild male-factor infertility because it is less invasive and less costly than IVF.
The procedure is well-established and is used across a range of fertility challenges, from unexplained infertility to ovulation disorders and male fertility concerns. It can be performed in a natural cycle or in combination with ovarian stimulation to improve the chances of pregnancy. When IUI has not been successful after several cycles or when more complex barriers are present, in vitro fertilization (IVF) is typically the recommended next step.
Who Makes a Good Candidate for IUI?
IUI is a flexible treatment option that can benefit a wide range of patients. Individuals and couples who are ideal candidates for IUI include those with the following:
- Unexplained infertility after several months of trying to conceive
- Mild male factor infertility, such as low sperm count or reduced sperm motility
- Ovulation irregularities or hormonal imbalances affecting fertility
- Cervical factor infertility, including hostile cervical mucus
- LGBTQI+ individuals and same-sex couples using donor sperm
- Single individuals building their families with donor sperm
Patients best suited for IUI typically have open and unblocked fallopian tubes and adequate ovarian reserve. A comprehensive evaluation, including medical history, hormonal testing, and reproductive imaging, helps our team determine whether IUI aligns with your individual needs and goals.
How the IUI Procedure Is Performed
The IUI process at Chedid Grieco begins with an in-depth consultation in Miami, where our team reviews your medical history, confirms candidacy, and outlines a personalized treatment plan. From there, treatment moves forward at our Brazil facility with close monitoring throughout the cycle.
Most patients undergo ovulation induction prior to the procedure to stimulate the ovaries and improve the chances of successful fertilization. This may involve oral medications or injectable hormones, depending on your individual profile. Once follicle development is confirmed through ultrasound monitoring, a trigger injection of human chorionic gonadotropin (hCG) is administered to time ovulation precisely. For patients exploring fertility preservation or looking to minimize injections, our team discusses all available approaches during the consultation phase.
Approximately 24 to 36 hours after the trigger shot, the IUI procedure is performed. A semen sample is collected and processed in the lab to concentrate the most motile sperm. A thin catheter is then gently inserted through the cervix and into the uterus, where the washed sperm are deposited. The procedure is quick and typically well-tolerated, taking only a few minutes to complete. Patients may resume normal activities immediately after. About two weeks later, a pregnancy test determines whether implantation has occurred.
What to Expect Regarding Success Rates and Risks
Success rates for IUI vary based on several factors, including the patient’s age, the underlying cause of infertility, whether ovarian stimulation is used, and the number of cycles attempted. Patients with ovulation disorders tend to see higher success rates, while those with more complex fertility challenges may require additional cycles or a transition to IVF. Our team reviews your specific clinical picture during the consultation and provides realistic expectations based on your individual circumstances.
IUI is considered a safe procedure with a low risk of serious complications. Potential side effects include minor spotting or mild discomfort at the time of catheter insertion. There is a small risk of post-procedure infection, though this is minimized through sterile technique. If ovarian stimulation is used, our team monitors closely for ovarian hyperstimulation and discusses all risk factors with you before proceeding. All questions and concerns are addressed during your IUI consultation in Miami.
Frequently Asked Questions About IUI
If you are considering intrauterine insemination, you likely have questions about what the process involves and what to expect. Below are answers to some of the most common questions we hear from patients.
Is IUI painful?
Most patients describe the IUI procedure as mild to moderately uncomfortable, similar to a Pap smear. A thin catheter is gently passed through the cervix into the uterus, which may cause brief cramping. The procedure typically takes only a few minutes, and most patients resume normal activities immediately afterward with no significant discomfort.
How many IUI cycles should I try before moving on to IVF?
This depends on your age, diagnosis, and how your body responds to treatment. Most fertility teams recommend attempting IUI for two to four cycles before considering a transition to IVF. If you are over 35 or have specific fertility factors that reduce IUI success, your provider may recommend IVF sooner. Our team provides guidance tailored to your individual clinical picture at each consultation.
Can IUI be done with donor sperm?
Yes. IUI is commonly performed using donor sperm, making it a widely used option for LGBTQI+ individuals and couples, single parents by choice, and those whose male partners have significant fertility challenges. Our clinic welcomes all family structures and provides supportive, personalized care regardless of how your family is being built.
Does IUI require fertility medications?
Not always. IUI can be performed in a natural, unstimulated cycle, or it can be combined with ovarian stimulation to increase the number of eggs available and improve the chances of pregnancy. Whether medications are recommended depends on your diagnosis and overall fertility profile. Our team discusses the benefits and considerations of each approach during your initial consultation in Miami.
