IUI Fertility Treatment in Nepal — Intrauterine Insemination Guide A less invasive path to conception

IUI Fertility Treatment: An Overview

Intrauterine insemination (IUI), also called artificial insemination, is a fertility treatment where specially prepared sperm is placed directly into the uterus at the time of ovulation. It is one of the simplest assisted reproductive techniques, requiring no surgery and no egg retrieval, which makes it an attractive first-line option for suitable couples in Nepal and worldwide.

IUI helps overcome several common barriers to conception: cervical mucus that is hostile to sperm, mild male factor infertility with reduced count or motility, and unexplained infertility where no specific cause is found. By concentrating the best sperm and placing it past the cervix, IUI gives sperm a head start toward the egg.

IUI is not suitable for everyone. Blocked fallopian tubes, severe male factor infertility or significantly reduced ovarian reserve usually require IVF instead. This guide explains how IUI works, what determines success and how it fits into the broader fertility treatment landscape in Nepal.

How IUI Fertility Treatment Works

IUI begins with a fertility assessment of both partners: semen analysis, hormonal tests such as AMH and FSH, and imaging to confirm at least one open fallopian tube and a receptive uterine cavity. If these are favorable, IUI can be attempted.

During a treatment cycle, the woman either uses her natural cycle or takes ovulation-inducing medication to mature one or more follicles. Ultrasound monitoring tracks follicle growth, and a trigger injection times ovulation precisely. Around 24–36 hours later, prepared sperm is placed into the uterus via a thin catheter.

Sperm preparation is a key step: the semen sample is processed to concentrate the most motile, morphologically normal sperm and remove seminal fluid and debris. This dramatically increases the number of capable sperm reaching the egg compared with natural intercourse.

• IUI places prepared sperm directly into the uterus at ovulation.
• Natural-cycle or stimulated cycles are both options depending on diagnosis.
• Sperm preparation concentrates the healthiest sperm for insemination.
• Ultrasound monitoring ensures correct timing of the procedure.
• The procedure is quick, minimally invasive and done in the clinic.
• A pregnancy test is performed about 14 days after insemination.

Who Benefits from IUI Treatment

IUI is most effective for couples where the barrier to conception is relatively mild. Couples with unexplained infertility — where standard tests show no clear cause — often try IUI as a first step because it is simple, affordable and non-invasive.

Male factor infertility is another common indication, provided sperm parameters are not severely abnormal. Sperm preparation helps compensate for reduced count or motility, though severe oligospermia or azoospermia requires IVF with ICSI or surgical sperm retrieval.

IUI is also used with donor sperm for single women, same-sex female couples and couples where the male partner has no usable sperm. It is less commonly used for severe tubal disease or advanced maternal age with diminished ovarian reserve, where IVF offers better odds.

• Unexplained infertility — often the first treatment tried.
• Mild male factor infertility — preparation compensates for reduced parameters.
• Cervical factor infertility — bypasses hostile cervical mucus.
• Mild endometriosis — may improve odds in selected cases.
• Donor sperm insemination — for single women, same-sex couples or azoospermia.
• Not ideal for blocked tubes, severe male factor or very low ovarian reserve.

IUI Success Rates and What Influences Them

IUI success rates per cycle are generally cited around 10–20% for women under 35, declining steadily with age. These figures are similar worldwide, including in Nepal, because they depend more on biological factors than geography. Cumulative success improves with multiple cycles, though most clinicians recommend up to 3–6 cycles before reassessing.

The strongest predictor of success is female age, particularly ovarian reserve measured by AMH and antral follicle count. Sperm quality after preparation, tubal patency, uterine cavity and correct timing of insemination also matter. Stimulated cycles tend to have slightly higher per-cycle success than natural cycles.

Unexplained infertility and mild male factor tend to have the best IUI outcomes; cervical factor and mild endometriosis are intermediate. Setting realistic expectations is important — IUI is a reasonable first step, not a guaranteed solution, and couples should be prepared to move to IVF if several cycles fail.

• Per-cycle success is roughly 10–20% for women under 35.
• Success declines significantly after age 35 and more steeply after 40.
• Multiple cycles improve cumulative chances; up to 3–6 are typical.
• Stimulated cycles have slightly higher per-cycle success than natural cycles.
• Good sperm preparation, correct timing and tubal patency all influence outcome.
• IUI is not a guarantee — IVF may be needed if cycles fail.

IUI vs IVF: How They Compare in Nepal

IUI and IVF are both assisted reproductive technologies but differ fundamentally. IUI places sperm in the uterus and lets fertilization happen naturally in the fallopian tube; IVF retrieves eggs, fertilizes them in a laboratory and transfers embryos to the uterus. IVF has higher per-cycle success rates but is far more expensive and invasive.

In Nepal, the cost difference is substantial. IUI typically costs a fraction of a single IVF cycle, making it the more accessible option for many couples. IVF success rates per cycle are higher — often 30–50% for younger women — but the total cost of multiple IVF cycles can exceed that of several IUI attempts.

The choice between IUI and IVF depends on diagnosis, age, budget and time. IUI is reasonable for mild problems in younger couples; IVF is preferred for blocked tubes, severe male factor, advanced maternal age or repeated IUI failure. A fertility specialist can help determine the best path.

• IUI is simpler, cheaper and less invasive than IVF.
• IVF has higher per-cycle success rates but costs much more.
• IUI is first-line for mild problems; IVF for severe factors.
• IUI does not require egg retrieval or embryo transfer.
• IVF bypasses tubal and cervical issues entirely.
• The choice depends on diagnosis, age, budget and timeline.

IUI Costs, Availability and Getting Started in Nepal

IUI is available at several fertility clinics in Kathmandu, including Thamel Clinic. Costs vary by whether a natural or stimulated cycle is used, but a typical IUI cycle in Nepal ranges from roughly Rs. 8,000 for a natural cycle to Rs. 30,000 for a stimulated cycle including medication and monitoring. Initial fertility assessment adds several thousand NPR.

Because IUI is less expensive than IVF, it is often the first treatment couples try. However, hidden costs can accumulate: fertility medications, repeated monitoring visits, multiple cycles and eventual IVF if IUI fails. A clear cost discussion before starting helps couples plan realistically.

To get started, book a fertility consultation where both partners are assessed and a personalized treatment plan is created. The team will explain whether IUI is appropriate, which protocol to use, expected costs and realistic success rates based on your specific situation.

• IUI is available at fertility clinics in Kathmandu, including Thamel Clinic.
• Natural-cycle IUI costs roughly Rs. 8,000–15,000 per cycle.
• Stimulated IUI costs roughly Rs. 15,000–30,000 including medication.
• Initial fertility assessment adds several thousand NPR.
• Multiple cycles may be needed, so budget accordingly.
• IVF is more expensive but may be needed if IUI fails.
