Previous tests should be carefully reviewed to ensure that the diagnosis is, in fact, "unexplained," and that no test has been omitted or missed. It may sometimes be necessary to repeat certain investigations. For example, if a previous laparoscopy has been done by a single puncture and reported as normal, it may be necessary to repeat the laparoscopy with a double puncture, to look for early endometriosis. 
IVF is a type of assisted reproductive technology used for infertility treatment and gestational surrogacy. A fertilised egg may be implanted into a surrogate's uterus, and the resulting child is genetically unrelated to the surrogate. Some countries have banned or otherwise regulate the availability of IVF treatment, giving rise to fertility tourism. Restrictions on the availability of IVF include costs and age, in order for a woman to carry a healthy pregnancy to term. IVF is generally not used until less invasive or expensive options have failed or been determined unlikely to work.
Unlike the simpler process of artificial insemination -- in which sperm is placed in the uterus and conception happens otherwise normally -- IVF involves combining eggs and sperm outside the body in a laboratory. Once an embryo or embryos form, they are then placed in the uterus. IVF is a complex and expensive procedure; only about 5% of couples with infertility seek it out. However, since its introduction in the U.S. in 1981, IVF and other similar techniques have resulted in more than 200,000 babies.

The treatment options for unexplained infertility are several and the treatment results are promising. Expectant management can be recommended if the woman is under 28-30 years of age and the infertility duration is less than 2-3 years. In vitro fertilization (IVF) has revolutionized the treatment of infertile couples, as well as profoundly increasing the basic understanding of human reproduction. IVF can be used as both a diagnostic and a therapeutic tool in couples with unexplained infertility. The pregnancy rates with IVF are good, at 40% per treatment cycle. In addition, the outcome of pregnancies among women with unexplained infertility is generally comparable to that of spontaneous and other pregnancies using assisted reproductive technologies.


When you face secondary infertility, you’re dealing not only with the typical ups and downs of TTC, but also with the additional emotional fallout that is unique to those having difficulty getting pregnant with baby number two. In addition to feeling disappointed and upset, you may also be feeling shock (“I got pregnant so easily the first time, there’s no way I could have infertility problems”), guilt (“I already have a child, so I should be happy”) and even isolation (“I can’t connect with the people facing primary infertility and I can’t connect with my friends who have multiple kids”). How do you reconcile these conflicting emotions — and how do you tackle them while trying to raise the child you already have?


The cost of IVF rather reflects the costliness of the underlying healthcare system than the regulatory or funding environment,[168] and ranges, on average for a standard IVF cycle and in 2006 United States dollars, between $12,500 in the United States to $4,000 in Japan.[168] In Ireland, IVF costs around €4,000, with fertility drugs, if required, costing up to €3,000.[169] The cost per live birth is highest in the United States ($41,000[168]) and United Kingdom ($40,000[168]) and lowest in Scandinavia and Japan (both around $24,500[168]).

Secondary infertility (SI) is defined by doctors as the inability to conceive or carry to term a second or subsequent child. You may not have heard of it but you probably soon will, because it's on the increase. A US study revealed that, in 1995, 1.8 million women suffered from secondary infertility; in 2006, it was 3.3 million. SI now accounts for six out of 10 infertility cases.

3-6 months of treatment with Clomid pills (clomiphene citrate) might improve fertility by as much as 2 times as compared to no treatment. This is a very low level infertility treatment. Infertility specialists do not usually recommend Clomid treatment( without insemination) for unexplained infertility for women over the age of about 35. Most fertility specialists do not use it (without IUI) on any couples with unexplained infertility. If a woman is already having regular periods and ovulating one egg every month, giving Clomid, which will probably stimulate the ovaries to release 2 or 3 eggs per month (instead of one) is not really fixing anything that is broken - and is not likely to be successful.
