After a brief medical examination a healthy couple came to know that both of them are unable
to proudce functional gametes and should look for an 'ART' (Assisted Reproductive Technique).
Name the 'ART' and the procedure involved that you can suggest to them to help bear a chlid. (2)
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.
