Cramping after iui

Intrauterine Insemination (IUI), also known as artificial insemination, is an infertility treatment available for couples who find it difficult to conceive. It is a process through which the sperm that are selected are placed into the uterus using a catheter. Many women may experience cramping after IUI. IUI is usually performed during the time of ovulation, which increases the chances of becoming pregnant. The eggs must be released for the sperm to meet and implant.

If infertility relates to scarce eggs or low-quality eggs or to increase the chances of successful conception, the fertility specialist may prescribe certain medications during the treatment cycle to ensure the adequate release of eggs. The reason for infertility determines the method of IUI. In this article, we shall discuss more about IUI, what happens after the procedure, and if cramping after IUI is common.

What is IUI?

IUI or intrauterine insemination is the first line of treatment for couples struggling to conceive. This process involves inserting washed and concentrated sperm into the uterus around the time of ovulation and the release of the oocyte. This process increases the chances of conception by allowing the healthy sperm better chances of swimming to and fertilizing the egg or the oocyte.

Intrauterine insemination is the most common fertility treatment that infertile or struggling couples receive. The treatment cycle may or may not involve hormones and medications to stimulate the ovaries and cause the follicles to release multiple mature eggs. This decision lies with the fertility expert who will do a thorough examination of the couple and decide the best line of treatment protocol.

IUI is less invasive and more affordable compared to advanced treatment methods such as IVF and ICSI.

After an IUI procedure, life will be back to an average pace. You may experience cramping after the procedure. The cramping usually resolves on its own within a period of 48 to 72 hours. Your doctor may recommend pain medications to help with the pain. You must remember not to use any over-the-counter medications for pain or discomfort without talking to the doctor.

Doctors recommend waiting for 48 hours before resuming sexual life, mainly if tenaculum forceps are used. However, you must avoid consuming alcohol, smoking, drugs, and certain other medications since these may interfere with the treatment process, fertilization, and proper growth and development of the embryo.

Your doctor may also recommend starting or continuing pre-vitamins, including folic acid, to prepare your body for the upcoming pregnancy and to support the growth of the embryo.

Causes Of Cramping After IUI

Cramping is one of the most common after-effects of an IUI and many women who undergo IUI may experience cramping for 48 to 72 hours after this procedure while some women may not experience any pain. There are many reasons for cramping post-IUI.

1. Ovulation

The IUI is performed during ovulation, which may be the primary reason for the cramping.  The release of the egg or multiple eggs during ovulation which coincides with the IUI procedure may result in cramping.

2. The Procedure

During IUI, sperm is inserted into the uterus through the catheter. Some women experience may cramping when the catheter is removed. However, some women continue to experience cramping even after removing the catheter. This may happen due to the catheter irritating the uterus during the procedure.

3. Stimulation Drugs

 In most IUI protocols, doctors may recommend medications and hormones to ensure the production and release of multiple mature eggs to increase the chances of successful fertilization and conception. This may also cause conception.

4. Prostaglandin
