The couple may try IVF to bear a chlid.

1. IVF(In Vitro Fertilisation).Fertilisation outside the body in almost simliar conditions as that

   in the body. Then embryo is transfer in the female reproductive track. This is known as test

   tube baby programme. In this method, Ova from the wife/donor(female) and sperms from

   the husband/donor (male) are collected and are induced to from zygote in simulated

   conditions in the laboratory. The zygote or early embryos(with upto 8 blastomeres)  

   are then transferred into the fallopian tube.

2. ZIFT(Zygote Intra Fallopian Transfer). Ovum from wife/donor female is removed 

   surgically after hormonal stimulation of the follicles. It is then fertilized by her

   husband's/donor male's sperm in a laboratory dish containing a nutrient broth.

   The zygote or early embryo upto 8 blastomeres is then transferred into fallopian 

   tube (ZIFT) or embryo with more than 8 blastomeres is transferred into urterus,

   Intra Uterine Transfer(IUT), to complete further development of zygote or embryo.

   It is carried in sterilised conditions. With proper medical care, the mother gives birth 

   to a normal child on the completion of gestation.
