Most of the couples that already have a child do not even think that may have a problem conceiving another one. Usually they are sure that if they didn't have problems with their first child there would be no problems in future. And that is only until they try to make another baby. So secondary infertility is usually a surprise. And that becomes a big problem and not only physically but also psychologically. Most couples are simply not ready for such an outcome.
Secondary infertility factors can be different but all these secondary infertility factors need being treated accordingly. If couples with primary infertility need special medical assistance in treatment of their problem with secondary infertility results in the need for that assistance even more.
All the secondary infertility factors can be divided into several groups. The first are age and couple factors.
In most cases of secondary infertility age is the main factor. Today there is a lot of information on age and woman's fertility. At the age of 35 there is a certain decrease of woman's fertility. At the age of 40 chances to get pregnant are even lower. And at the age of 45 a possibility of natural conception with unprotected and well timed intercourse is only about 6%.
A smaller amount of data and written papers are available on how age affects male fertility. Usually men produce sperm through all their adult life. But certain studies in that area show that there is a decrease in both quantity and quality of sperm an older man produces. All that makes age the main factor of all the secondary infertility factors.
The so-called couple factor is also present - it is especially a problem if you have a "new partner". In that case, males or females who have previously conceived successfully may experience problems with a new partner. But among all the secondary infertility factors cases caused by a couple factor are not numerous.
Different partners pathologies can also lead to different sorts of secondary infertility. And that kind of secondary infertility factors is very wide - there are many reasons in the area of pathology.
Successful conception in all cases depends on production of healthy eggs and sperm and if some problem occurs with any gamete that will lead to a fertility decrease. For women main problems usually are tubal blockage and abdominal adhesions - one third of all cases of secondary infertility are caused by these factors. Among secondary infertility factors for women about 25 % are ovulatory issues like anovulation, ovulation irregularities and premature ovarian failure. For men most usual secondary infertility factors are different defects in spermatogenesis and blockage in the semen delivery system. In many cases, different degrees of impotence can also play a significant role in man's fertility.
Anyway it is necessary to understand clearly that there are many different secondary infertility factors and several of them can occur at the same time. And a great number of these factors can develop after the first successful conception. So an appropriate medical evaluation is needed for couples experiencing problems with second conception.
