Three Types of Test to Determine Unexplained Infertility

February 7th, 2010

Unexplained infertility can be one of the most difficult problems a couple trying to conceive can go through. It can cause self-doubt as well as a variety of fights between the two partners. Perhaps it is the unknown factors present that can spur arguments. The conception process can take years and the tests can be many. If the couple has tried for over two years to become pregnant then there are additional tests that can be run.

There are different tests that can be ordered before giving a final diagnosis of unexplained infertility. The first step, even when fertility is not an issue, is to take a complete medical history of the couple. This will involve a history of monthly cycles as well as blood work drawn. Many injuries or diseases can cause infertility so it is important for both the man and woman to be thorough in their detailed history.

The second test is called a Hysterosalpingogram. This test is performed by the radiology staff at a hospital and involves an x-ray being taken after dye is put into the uterus through an IV. The radiologist and fertility specialist can then see if the fallopian tubes have any blockage or if there is any damage to the uterus that may be causing the infertility.

The third test is for a semen analysis. The male must ejaculate into a cup so that the lab can see how high his sperm count is as well as the motility of the sperm. The lower the count and motility, the less likely fertilization is to occur.

Unfortunately there is a bit of panic at the diagnosis of unexplained infertility. In reality it can actually be any number of known reasons for the conception to not be occurring. It can be anything from the eggs not being able to be entered by the sperm to even something being wrong on a genetic level between the two. Unexplained infertility can also apply to after the egg has been fertilized but has a failure to implant normally in the uterus. It can also be a wide variety of reasons all coming together for the same result: a failed pregnancy attempt.

It is possible for men to continue to have children at any age but time is not an ally for a woman’s eggs. If unexplained infertility continues to stop the conception process, there are alternatives. The couple can consider using donor eggs or sperm. There are even surrogate mothers who will carry the child for the woman. In a world full of children needing loving homes, adoption can be a great alternative. Just remember that biology does not a parent make.

IUI For Unexplained Infertility – The IUI Risk Factors

February 5th, 2010

The success rate of IUI for unexplained infertility is not high yet it still gives those who have exhausted many previous options to get pregnant plenty of hope that conception will and can take place.

What Is IUI?

IUI stands for intrauterine insemination and is a step pursued by those hampered by unexplained infertility. It’s a relatively simple process and shouldn’t cause one any concern in it’s application.

The process involves the insertion of a catheter by way of the cervix which then leads to the injection of sperm into the uterus. The entire process only takes several minutes and discomfort levels for the patient are extremely low.

Timing for IUI treatment is critical and really needs to take place several hours before and after ovulation. The suggested time period is 4-6 hours however, in some cases this can be extended slightly. It will depend on a person’s individual situation and the doctor’s discretion.

Success Rate Of IUI

So how successful is IUI for unexplained infertility? Well, success is not high however, there are several factors which can push up the success rate. It’s worth remembering that this process isn’t the be all and end all of the journey to conception.

IUI is simply another option available to unexplained infertility patients and if it’s not successful, then other treatment methods will be considered.

The rate of success is commonly put at between 5-10 per cent which is low by the standard of numbers but in relative terms, especially where infertility is concerned, it’s high enough to give people plenty of hope. Some reports suggest success rates of over 20 per cent but this co-incides with multiple follicles. Sperm count is another factor which can determine the overall result.

The number of follicles has an impact. One follicle will put a person in the single digit chance of success range however, when two or more are used, the chances increase.

Risks And Cost Of IUI

The risk factors surrounding IUI for unexplained infertility are not life threatening. The procedure is relatively simple and any risks are usually associated with some form of discomfort for the patient. Infection could be an issue if the sperm is not properly prepared.

Costs vary considerably. It can depend on a number of preparation and follow up treatments which can balloon into the mid four figure range. The costs can start at around $200. The actual procedure itself is not expensive but by the time other factors such as ultra sound and medications are taken into account then the price can increase significantly.
