A. A woman cannot produce ovum
B. When a man or woman has a genetic disease
C. Problem in coitus
D. Both (A) and (B)

Answer 1

Hint: Assisted reproductive technology (ART) includes medical procedures used primarily to address infertility.

Complete answer: The process of sexual intercourse is bypassed in ART and fertilization of the oocytes occurs in the laboratory environment.
1. The procedures of ART are in vitro fertilization, intracytoplasmic sperm injection (ICSI), cryopreservation of gametes or embryos, and/or the use of fertility medication.
2. ART may also be referred to as fertility treatment.
3. It mainly belongs to the field of reproductive endocrinology and infertility.
4. ART is a process that is done not only when a woman has some birth defects but it is also done when both have defects.

Additional information: IVF: In vitro fertilization (IVF) is a process of fertilization where an egg is combined with sperm outside the body, in vitro ("in Petri dish").
The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova from the woman's ovaries, and letting sperm fertilize them in a liquid in a laboratory environment.
After the fertilized egg (zygote) undergoes embryo culture for 2–6 days, it is implanted in the same or another woman's uterus, with the intention of establishing a successful pregnancy.
ICSI: Intracytoplasmic sperm injection (ICSI) is an in vitro fertilization (IVF) procedure in which a single sperm cell is injected directly into the cytoplasm of an egg.

So, the answer is D. Both (A) and (B)

Note: Some forms of ART may be used with regard to fertile couples for genetic purposes. ART is also used in surrogacy arrangements, although not all surrogacy arrangements involve ART.
