The use of in-vitro fertilization is increasing and becoming popular and well known among infertile couples. Due to high cost, the in-vitro fertilization techniques should not be used in normally manageable infertility problems. Before in-vitro fertilization is used, the couple should be advised and counseled to avail “assisted reproductive technology”, where doctors help the infertile couple to conceive by use of various non-invasive techniques, such as use of ovulation inducing medications, counseling of couple and educating the infertile couple about the normal physiology of menstrual cycle and many other methods. If assisted reproductive technology methods fail to produce conception, in-vitro fertilization is indicated. In case of older couple e.g. woman’s age of approximately 40 years, in-vitro fertilization can be tried before trying assisted reproductive technology methods, because after 40 years the chance of pregnancy declines sharply even in normal individuals (women). But if the age of the infertile woman is 30 years or less, assisted reproductive technology methods should be tried first.
Some of the indications of in-vitro fertilization are:
Female infertility:
In case of female infertility e.g. problems in fallopian tube, in-vitro fertilization is indicated. The problems of fallopian tube may blockade of fallopian tube or inflammation of fallopian tube due to infection such as tuberculosis, any anatomical defect in fallopian tube etc. Problems in fallopian tubes may result in infertility and the environment in the tubes become unfriendly for fertilization to take place. Hence, IVF is indicated.
Male infertility:
Male infertility is an indication of in-vitro fertilization. Male infertility may be due to poor sperm quality (lower than normal sperm count, low percentage of viable sperms, high percentage of dead or inactive sperms etc. constitute poor sperm quality). If sperm quality is poor sperms can not fertilize ovum from the woman.
Other indication:
In case of male sterility (absence of sperm in a man’s semen) in-vitro fertilization can be done with donated sperm from a donor. In-vitro fertilization is also done in case of surrogacy (where the woman providing the egg isn’t the same who will carry the pregnancy to term).
For IVF to be successful (that is fertilization to delivery of baby) the requirements are healthy ova, sperm to fertilize the ova and uterus to continue pregnancy to term and delivery. Absence of any of these can not lead to successful pregnancy in in-vitro fertilization.
N.B. a great advantage of IVF is possibility to rule out presence of genetic disorders in the baby by doing Pre-implantation Genetic Diagnosis or PGD.
