Upwards of 30% of couples seeking fertility care are labeled with unexplained infertility. Given that over 50% of couples’ infertility struggles are at least partially attributable to the male, understanding the source of male infertility could allow for improved care. The limited set of male tests can only detect the major causes of infertility (i.e., azoospermia) leaving the less obvious factors invisible.
Intrauterine insemination is the process whereby a clinician will place a concentrated specimen of sperm in your uterus. For this procedure, he or she will insert a speculum into your vagina in order to better visualize your cervix. He or she will then pass a soft, thin catheter through the cervix opening and into the uterus. The clinician will introduce the washed sperm into the uterus through this catheter. The procedure is done in our office and takes 1 to 2 minutes. It is not painful and does not require anesthesia. You can return to normal daily activities immediately after an IUI.
Sometimes problems getting pregnant for a second or subsequent time are related to a complication that occurred in a prior pregnancy or prior to delivery (damage to the uterus, for instance). But most often, secondary infertility is caused by the same factors that would cause primary infertility — issues like advanced age, obesity, ovulation problems and so on.
Treatment with Clomid tablets plus IUI improves fertility rates. For unexplained infertility, studies have shown that for women under 35, monthly success rates for Clomid plus insemination are about 10% per cycle. This pregnancy rate holds up for about 3 tries and the success rate is considerably lower after that. More about success rates with IUIs is on the insemination page and on the Clomid for unexplained infertility page. The insemination component boosts fertility more than the Clomid does - but success rates are higher when both are used together.
In some cases, laboratory mix-ups (misidentified gametes, transfer of wrong embryos) have occurred, leading to legal action against the IVF provider and complex paternity suits. An example is the case of a woman in California who received the embryo of another couple and was notified of this mistake after the birth of her son. This has led to many authorities and individual clinics implementing procedures to minimise the risk of such mix-ups. The HFEA, for example, requires clinics to use a double witnessing system, the identity of specimens is checked by two people at each point at which specimens are transferred. Alternatively, technological solutions are gaining favour, to reduce the manpower cost of manual double witnessing, and to further reduce risks with uniquely numbered RFID tags which can be identified by readers connected to a computer. The computer tracks specimens throughout the process and alerts the embryologist if non-matching specimens are identified. Although the use of RFID tracking has expanded in the US, it is still not widely adopted.
Secondary infertility can be traced to either partner or both partners. About one-third of cases originate in women and about one-third originate in men. In the remaining one-third, the cause is due to a combination of factors or isn’t known. Increased age, complications from a prior pregnancy or surgery, increased weight, medications, sexually transmitted diseases, impaired sperm production, alcohol abuse, and smoking are all examples of secondary infertility in women and men.
The diagnosis of infertility is often very overwhelming for patients. There is a plethora of information served to them. First is, they can conceive a child only through medical treatment. Second is, the insurmountable amount of information that is hard to comprehend. New medical jargon along with recommendations for treatments and tests that are completely unfamiliar can be very intimidating for the newly diagnosed. Indira IVF's Reproductive Specialists believe in creating a partnership with the patient, and we have found that the most successful partnerships occur when the patient is well-informed and can play an active role in their treatment. We value an open and ethical relationship with each patient in an environment that fosters trust and mutual respect, an environment where questions are welcome and encouraged.
For example, a deaf British couple, Tom and Paula Lichy, have petitioned to create a deaf baby using IVF. Some medical ethicists have been very critical of this approach. Jacob M. Appel wrote that "intentionally culling out blind or deaf embryos might prevent considerable future suffering, while a policy that allowed deaf or blind parents to select for such traits intentionally would be far more troublesome."
Repeated failed rounds of IVF can help identify causes of infertility. For example, if sperm and egg quality are normal, then the conception issue may be rooted at the embryonic or implantation level. In other words, if IVF fails to result in pregnancy despite successful fertilization, embryonic development or implantation may be to blame. Still this is a very expensive way to start getting answers.
