4(a) transfer of an ovum from a donor into the fallopian tube of a woman who cannot make ova—
5(d) 1.5% per year(26 − 11) per 1,000 = 1.5%
6(a) 72 hours of intercourse—

8(a) Both A and R are true, and R is the correct explanation of A.A is true: AIDS is caused by a virus (HIV) and spreads through body fluids. R is true and explains A.

11a hormone-releasing IUD; it acts in the uterus to stop fertilisation or implantation—
12IVF–ET: fertilisation outside the body, then transfer of the embryo; GIFT: transfer of an ovum from a donor into the fallopian tube of a woman who cannot make ova—
13trichomoniasis: a protozoan (Trichomonas); genital herpes: a virus (herpes simplex). Avoid sex with unknown or several partners, always use condoms, and seek early treatment if in doubt—
14about 1.54 times; 298 million846 ÷ 548
15it gives correct information and removes myths about sex-related matters and reproductive health—
16progestogen–oestrogen injections and implants: a hormonal method; Progestasert and LNG-20: a hormone-releasing IUD. Advantages depend on the method: natural methods have no side effects; barriers also protect against STIs; IUDs and pills are highly effective; surgical methods are permanent—
17Natural: periodic abstinence (days 10–17), withdrawal, lactational amenorrhoea. Barrier: condoms, diaphragms, cervical caps and vaults, often with spermicides. IUDs: non-medicated (Lippes loop), copper-releasing (CuT, Cu7, Multiload 375), hormone-releasing (Progestasert, LNG-20). Hormonal: oral pills (including Saheli), injections and implants. Surgical (terminal): vasectomy and tubectomy.—
18118,900 people; 2.9% per year. Reasons: fewer deaths of mothers and infants, better health care, more people of reproductive age. Measures: education and awareness, contraception, raising the marriageable age (18 for women, 21 for men), incentives for small families—

20artificial insemination (IUI): placing semen from the husband or a donor into the vagina or uterus. ICSI: injection of a sperm directly into an ovum in the laboratory. Each suits couples whose infertility has a cause that technique can get around. Limits: they need expensive specialised facilities and trained staff, and there are emotional, ethical and social issues; adoption is another option—
