After looking at several of the organ systems within the human body in overview in Chapter 2, the next three chapters will now look at some of these systems in more detail. This chapter on Human reproduction starts off by looking at the purpose of reproduction and how humans mature during puberty in order to be able to reproduce. This will be very relevant to your learners as they are in this stage in their lives at the moment. Be aware that learners might not feel comfortable discussing reproduction in the classroom, and older teens might laugh or make inappropriate jokes to conceal their own discomfort. Some tips for when teaching human reproduction Respect your learners questions and concerns. Some of them may not have had an opportunity before to ask questions about reproduction, especially if their parents did not feel comfortable discussing this with them. This is a sensitive topic, and learners might be embarrassed to ask questions. Encourage your learners to ask questions and not be embarrassed. Learners must be told to phrase their questions carefully and to use scientific words, with no vulgar expressions. You yourself, as the teacher, must only use scientific terms. Discuss processes openly so that learners are comfortable within the classroom environment to talk and learn about reproduction and how it influences their lives. Discourage and discipline any laughing or disrespectful behavior from other students.

Also, if you bring in an expert, such as a gynecologist or midwife, learners might take the subject more seriously. If necessary, you can separate boys and girls. For example, if you are showing a graphic video about the female reproductive organs, it might be useful to have the boys watch a similar video in another room that explains the male reproductive organs. Avoid portraying the reproductive system in a negative light or as forbidden as this will only add to some of the discomfort that learners might already feel. At this stage in their lives, learners are already very interested in reproduction and the changes that their bodies are going through. This is natural and should be embraced so that they are educated and can make informed choices about their sexual health going forward.

You have previously learnt that reproduction is one of the seven life processes, and like all organisms, humans need to reproduce to ensure the survival of the species. You can use this section to open up discussion about population growth and population control. At the end of the chapter there is a debate regarding contraceptives but teachers may choose to include a discussion on the different ethical points of view regarding contraceptives at this point already. Video on our world population growth. Reflecting on population growth. An interesting suggestion if you have an internet connection and a projector or smartboard to display a website, is to open up the link provided here in the visit box on our Breathing Earth. This simulation very clearly shows how our population is growing. You can open up the link at the start of the lesson and leave it running for the duration. Then at the end of the lesson, you can see how much the population of the world has grown during your one lesson. Alternatively, if you do not have an internet connection in your classroom, ask some of your learners to take out their mobile phones and go to the site. Even if you only have a few mobile phones within the classroom, you can get learners to each take a look at the site at the start and end of the lesson. Do not be afraid to embrace the technology that your learners are using on a daily basis They most likely have their cellphones in their pockets in class anyway, unless they have been banned during school hours. A simulation to show population growth http www. Have a look at the website link provided in the visit box about our Breathing Earth. This will give you an idea about how our population is growing. In 2. 01. 1 the worlds population grew to 7 billion people, one billion more since 1. Medical advances and increases in agricultural production food allow more and more people to live longer lives. In ancient times, countries such as India, Rome and Greece, saw a large population as a source of power. The Romans even made laws about how many babies a couple could have and punished those who did not follow the rules. Yet Confucius 5. BC thought that too many people was a problem, as there wouldnt be enough food to feed everyone, leading to war and famine and various other problems. Today in China this philosophy still applies and couples are only allowed one baby and are heavily taxed if they have more than one. South Africas population grew by 1. This is according to the countrys latest national census which took place in 2. The last census took place 1. QUESTIONS These questions are meant to stimulate discussion within your class. You can go through these as a class or learners can then do them individually and then discuss their answers. List any possible reasons why you think South Africa would want to have a large population. Learner dependent answer. Might include more people so more manpower and more taxes might include religious or cultural bias etc. What are some advantages and disadvantages to the country in which the number of children per couple is limited so that the population growth is limited Advantages lower population growth lower pressure on the countrys resources lower drain on resources, particularly on the education resources higher standard of living for families. Disadvantages fewer people to pay taxes religious or cultural non compliance might lead to revolt. Predict what possible long term problems might arise if the population in South Africa continues to grow at the fast rate at which it is currently growing. Top 1. 0 facts about anti mullerian hormone levels and ovarian reserve testing. Anti mullerian hormone AMH is the substance that is responsible for destroying the mullerian ducts female reproductive organs in developing male embryos. An important discovery was the synthesis of AMH by granulosa cells the cells surrounding a mature egg and this was followed by the development of accurate blood tests to measure AMH. For the past 2. 0 years the importance of AMH with regard to ovarian function has been extensively studied. AMH is produced in the greatest amounts by antral follicles measuring lt 6 mm. Follicles 8 mm in diameter, theca cells and atretic follicles have virtually undetectable levels of AMH. The Sims 2 Bon Voyage Sauna'>The Sims 2 Bon Voyage Sauna. AMH is believed to impede the transition from primordial follicles into growing antral follicles. During ovulation induction, there is a decline in the AMH levels. This is to be expected as larger preovulatory follicles produce less AMH. AMH levels decline with age. A decline in AMH level may be the earliest marker of ovarian aging. This is followed by a decline in inhibin B and later by a rise in FSH levels. There are studies that suggest that AMH levels may in the immediate future be useful in predicting when a woman will undergo menopause. Obese women have 6. AMH levels than non obese women. This suggests that obesity might be associated with diminished ovarian reserve. AMH levels do not vary much throughout the menstrual cycle. Unlike FSH levels which should be measured on cycle days 2, 3 or 4, AMH levels can be measured on any day of the cycle. It can therefore serve as a unique untimed marker of ovarian reserve AMH levels predict ovarian response in IVF. Higher AMH levels are associated with greater number of retrieved eggs. On the other hand, lower AMH levels lt 0. L predict poor ovarian response with a sensitivity of 8. AMH levels 3. L are associated with an increased incidence of ovarian hyperstimulation syndrome. AMH levels can therefore be used as a guide when deciding on the dose of fertility drugs for ovulation induction. In patients with high AMH levels, the dose should be lowered and the opposite is true for patients with low AMH levels. AMH levels are NOT influenced by birth control pills, pregnancy or by Gn. RH agonists e. g. Leuprolide acetate, Lupron. In cancer patients that have undergone chemotherapy or radiation, AMH levels may be a marker of ovarian injury. A combination of age, AMH level, FSH level and ultrasound markers such as ovarian volume and antral follicle count can be used to assess ovarian reserve. At In. Via Fertility Specialists, we use AMH levels to screen our potential anonymous egg donors. We prefer donors with AMH levels 1. L.
