Foetoscope is used to monitor the foetal heart rate and other functions during late pregnancy and labour. The average foetal heart rate is between 120 and 160 beats per minute. An abnormal foetal heart rate or pattern may mean that the foetus is not getting enough oxygen and it indicates other problems. A hand-held doppler device is often used during prenatal visits to count the foetal heart rate. During labour, continuous electronic foetal monitoring is often used.
11.
1. Directly gametes cannot be transferred into the uterus, because the uterine environment is not suited for the survival of the gametes.
2. If the gametes directly transferred into the uterus, gametes will undergo degeneration (or) could be phagocytosed and viable zygotes will not be formed.
3. In this method, the own collected from a donor female is transferred to the fallopian tube of another woman.
4. The ovum has to be fertilized by the sperm of the woman's husband; the fallopian tube is the site for fertilization in a human female.
5. The gamete (ovum) if introduced into the uterus cannot move to the fallopian tube, the site of fertilization.
12.
(i) Creating awareness and providing medical assistance to build a healthy society.
(ii) Introducing sex education in schools to provide information about adolescence and adolescence related changes.
(iii) Educating couples and those in the marriageable age groups about the available birth control methods and family planning norms.
13.
(a) Transfer of an ovum collected from donor into the fallopian tube is called GIFT (Gamete Intra-fallopian transfer)
(b) Transferring of an embryo with more than 8 blastomeres into uterus is called IUT (Intra uterine transfer)
(c) Multi load 375 is a copper releasing IUD
14.
A collection of procedures, which includes the handling of gametes and/or embryos outside the body to achieve a pregnancy as known as Assisted Reproductive Technology. It increases the chance of pregnancy in infertile couples. ART includes intra-uterin insemination (IUI), in vitro fertilization, (IVF) Embryo transfer, (ET), Zygote intra-fallopian transfer (ZIPT), Gamete intrafallopian transfer (GIFT), Intra-cytoplasmic, sperm Injection (ICSI), .Preimplantation genetic diagnosis, oocyte and sperm donation and surrogacy.
(i) Intra-cytoplasmic sperm injection (ICSI): In this method only one sperm is injected into the focal point of the egg to fertilize. The sperm is carefully injected into the cytoplasm of the egg. Fertilization , occurs in 75 - 85% of eggs injected with the sperms. The zrgote is allowed to divide to form an 8 celled blastomere and then transferred to the uterus to develop a productive pregnancy.
(ii) Surrogacy: Surrogacy is a method of assisted reproduction or agreement whereby a woman agrees to carry a Pregnancy for another person, who will become the newborn child's parent after birth. Through in vitro fertilization (IVF), embryesz are created in a lab and are transferred into the surrogate mother's uterus.

Modification in lifestyle can also help in preventing cervical cancer. Healthy diet, avoiding tobacco usage, preventing early marriages, practicing monogamy and regular exercise minimize the risk of cervical cancer.
22.
Copper IUD's release free copper and copper salts into the uterus and suppress the sperm motility. They remain in uterus for 5-10 years. Eg: NovaT, Cu T-380.
23.
(i) Foetoscope is used to monitor the foetal heart rate and other functions during late pregnancy and labour. The average foetal heart rate is between 120 and 160 beats per minute.
