In the light of the above statements, choose the correct answer from the options given below.
Statement I is correct but statement II is false.
Statement I is incorrect but statement II is true.
Both statement I and statement II are true.
Both statement I and statement II are false.

Intra cytoplasmic sperm injection (ICSI) is a specialised procedure to form an embryo in the laboratory in which a sperm is directly injected into the ovum. Thus, it is in-vitro procedure.
In which of the following techniques, the embryos are transferred to assist those females who cannot conceive? [2020]
ZIFT and IUT
GIFT and ZIFT
ICSI and ZIFT
GIFT and ICSI
(1)
In vitro fertilisation, i.e., fertilisation outside the body in almost similar conditions as that in the body, followed by embryo transfer (ET) method. In this method, ova from the wife or donor (female) and sperms from husband or donor (male) are collected and are induced to form zygote under simulated conditions in the laboratory. The zygote or early embryos (with upto 8 blastomeres) could then be transferred into the fallopian tube (ZIFT – Zygote Intra Fallopian Transfer) and embryos with more than 8 blastomeres, into the uterus (IUT – Intra Uterine Transfer), to complete its further development.
Embryo with more than 16 blastomeres formed due to in vitro fertilisation is transferred into [2016]

Embryo with more than 16 blastomeres formed due to in-vitro fertilisation is transferred into uterus (intra-uterine transfer, IUT).
A childless couple can be assisted to have a child through a technique called GIFT. The full form of this technique is [2015]
Gamete Internal Fertilisation and Transfer
Germ cell Internal Fallopian Transfer
Gamete Inseminated Fallopian Transfer
Gamete Intra Fallopian Transfer

Gamete Intra Fallopian Transfer (GIFT) is an assisted reproductive technology in which both the sperm and unfertilised oocytes are transferred into the fallopian tubes. Fertilisation takes place in vivo (inside the body of the female).
Assisted reproductive technology, IVF involves transfer of [2014]
ovum into the fallopian tube
zygote into the fallopian tube
zygote into the uterus
embryo with 16 blastomeres into the fallopian tube

Assisted reproductive technologies (ART) include a number of special techniques which assist infertile couples to have children. An important technique of ART is test tube baby programme. The baby produced by conceiving in a culture dish and nursing in the uterus is called a test tube baby. This method involves in vitro fertilisation (IVF), i.e., fertilisation of male and female gamete outside the body in almost similar conditions as that in the body followed by embryo transfer (ET). Zygote or embryo upto 8 blastomeres is transferred into the fallopian tube (ZIFT – Zygote Intra Fallopian Transfer) and mature embryo with more than 8 blastomeres is transferred to uterus to complete its further development.
