Question

Methods like artificial insemination and embryo transplant are mainly used for _____.

Answer 1

Hint: Infertility is defined as not getting pregnant despite having carefully timed and unprotected sex for one year of the time. There are many techniques that are used so that the couple can get their child.

Complete answer: Infertility is a condition where even after 6 months of unprotected coitus the couple is unable to conceive. Then to help them the assisted reproductive techniques are used.
The artificial technique mainly includes:
1.Artificial insemination
2. In-vitro fertilization.
Infertility is mainly due to the inability of the male partner to inseminate the female with their sperm or due to a very low sperm count in the ejaculation. This can be easily corrected by the artificial insemination technique. In this technique, the semen is normally collected from the husband or a healthy donor and is artificially introduced in the vagina or the uterus of the female partner.
There are some techniques of embryo transplant which are also known as zygote intrafallopian transfer and intrauterine transfer. Embryo transfer can be achieved at day two or day three, or maybe later in the blastocyst stage, which was first performed in 1984.
So, the correct answer is infertility.

Note: In the human, the uterine lining (endometrium) needs to be appropriately prepared so that the embryo can implant. In a stimulated or cycle where a "frozen" embryo is transferred, the recipient woman could be given first estrogen preparations (about 2 weeks), then a combination of estrogen and progesterone so that the lining becomes receptive for the embryo.
