Study Notes
Contraception and STIs
- Contraception is the deliberate use of artificial methods to prevent or stop a pregnancy as a consequence of sexual intercourse
- Many contraceptive techniques are inspired by the causes of infertility
- Three main types of contraception: hormonal, barrier, and creating an unfavorable environment
- Hormonal contraception works by changing the hormones in the body to stop ovulation. No egg means no fertilization, meaning no pregnancy
- Barrier contraception works by creating a physical barrier to stop sperm from reaching the egg. Examples include condoms, spermicide, and female condoms
- Creating an unfavorable environment works by making the environment inhospitable for sperm and egg.
- STIs are sexually transmitted infections; they aren't always diseases but infections
- STIs are caused by bacteria, viruses, or parasites
- A sexually transmitted infection may pass from person to person through blood, semen, or vaginal fluids
- Some STIs are curable (e.g., syphilis, gonorrhea, chlamydia, and trichomoniasis); others aren't (e.g., hepatitis B, herpes simplex virus, HIV, and HPV)
- All STIs can be treated, and symptoms managed. Some are deadly
- STIs can affect fertility and can cause congenital infections in babies
- It is important to openly discuss sexual health with medical professionals to prevent STIs
Plant Reproduction
- Angiosperms use flowers for reproduction
- Special features of a flowering plant include:
- Ability to reproduce asexually (self-pollination)
- Ability to reproduce sexually (cross-pollination)
- Asexual reproduction:
- Use both organs to fertilize themselves
- Create a clone with the same characteristics
- More exposed to viruses/can adapt less effectively
