Intrauterine insemination (IUI) is a fertility treatment that involves placing washed and concentrated sperm directly into the uterus at the time of ovulation to facilitate fertilization. This procedure is commonly used to overcome various fertility challenges, including low sperm count, decreased sperm motility, cervical mucus abnormalities, and unexplained infertility. IUI is often recommended for couples who have been trying to conceive for an extended period without success or for individuals using donor sperm.

The process of intrauterine insemination typically begins with the female partner undergoing ovulation induction, which may involve taking fertility medications to stimulate the development and release of multiple eggs. Ovulation is monitored closely through hormonal assessments and ultrasound examinations to determine the optimal timing for insemination. Once ovulation is imminent, a semen sample is collected from the male partner or donor, processed in the laboratory to separate highly motile sperm from seminal fluid and debris, and prepared for insemination.

During the insemination procedure, a speculum is inserted into the vagina to visualize the cervix, and a thin, flexible catheter is used to introduce the prepared sperm into the uterine cavity. The placement of sperm directly into the uterus increases the likelihood of sperm reaching and fertilizing the egg, bypassing potential barriers in the cervix and enhancing the chances of conception. Following the procedure, the patient may rest for a short period before resuming normal activities.

While intrauterine insemination is a relatively simple and non-invasive fertility treatment, success rates vary depending on factors such as the cause of infertility, the woman's age, ovarian reserve, and the quality of sperm used. Couples may undergo multiple IUI cycles to achieve pregnancy, and additional diagnostic tests or treatments may be recommended if IUI is unsuccessful.

Overall, intrauterine insemination offers a less invasive and more affordable option for couples seeking assistance with conception compared to more complex fertility treatments such as in vitro fertilization (IVF). By providing a targeted delivery of sperm to the uterus at the optimal time for fertilization, IUI can help couples overcome certain barriers to conception and fulfill their dreams of starting or expanding their families.
