[Part 6]-B11- hormonal coordination 🫥🚺🚹 Flashcards
REACP: What day is ovulation ?
- ovulation, is day 14
What’s infertility ?
- infertility, is the inability to conceive a child or carry a pregnancy to term after trying for a certain period of time.
What are some reasons for infertility ? [4]
- some reasons for infertility:
- hormonal imbalances
- structural issues [such as- blockage of the fallopian tubes, which prevents sperm from meeting and then fertilizing an egg.]
- underlying medical conditions.
- and, eating disorders [such as anorexia nervosa]
What’s some treatments, for infertility ?
- some treatments, for infertility are:
- **a fertility drug
Describe how a fertility drug, can treat infertility? [4]
- a fertility drug, can be used to treat fertility.
- This is because, FSH and LH are given to a woman, since they may not produce enough follicle stimulating hormone [FSH], to stimulate the maturation of eggs in the ovaries.
- this artificial FSH, then stimulates the maturation of eggs in the ovaries.
- ; LH is then given, to stimulate ovulation.
- [therefore, this increases a woman’s chance of being pregnant, through sexual intercourse]
- Fill in the gaps: a fertility drug, increases a woman’s chance of being pregnant, through sexual intercourse
- a fertility drug, increases a woman’s chance of being pregnant, through sexual intercourse
What’s IVF ?
- in-vitro fertilisation [also know as IVF], is a process where mature eggs are removed from the female, and is then fertilised externally and replaced
What’s the process of IVF ? [6]
1) the mother is first treated with FSH and LH, causing several eggs to mature.
2) these matured eggs are then collected from the mother.
3) and at this point, sperm from the father is collected, and it’s then used to fertilise the eggs, in the laboratory
4) in the laboratory, these fertilised eggs then divide, to develop in tiny balls of cells known as embryos.
5) and, these embryos are know inserted into the mother’s uterus [womb]
6) these embryos can then develop in the mother, in the usual way [with the hope, it will implant and eventually develop into a baby]
How can FSH and IVF, be used to treat infertility ?
- FSH can be used to treat infertility because, FSH causes several eggs to mature in one of the ovaries [in a structure, called the follicle]
- and IVF can be used to rest infertility because after the process of IVF, embryos can then develop in the mother, in the usual way
What’s the advantages and disadvantages, of IVF ?
- advantage- IVF, gives a woman the chance, to have a baby of her own
- disadvantage- ; the success rate isn’t high, and the older the parents, the less likely it is they can have a baby.
Give another disadvantage of IVF [2]
- disadvantage- it’s emotionally [very] stressful for both parents
- disadvantage- IVF is also physically demanding on the mother.
- For example, in the treatment with fertility drugs, and the collections of eggs.
What’s a disadvantage, of IVF ?
- disadvantage- though IVF, can also lead to multiple births, which poses a risk for the babies and the mother [because, it increases the risk of complications such as a miscarriage, or gestational diabetes]. As 1 in 5 IVF pregnancies, are multiple pregnancies.
What’s another disadvantage, of IVF ?
- disadvantage- not all of the embryos created will be transferred to the mother, since many embryos are destroyed- which some people find unethical
- Fill in the gaps: IVF is _________ for the NHS [if it’s provided by the national health service].
- However, IVF is also _________ for individuals because, many people end up paying _________ of pounds, for repeated cycles of _________ treatments.
- IVF is expensive for the NHS [if it’s provided by the national health service].
- However, IVF is also expensive for individuals because, many people end up paying thousands of pounds, for repeated cycles of fertility treatments.
What’s steps one to two, of the IVF process?
1) the mother is first treated with FSH and LH, causing several eggs to mature.
2) these matured eggs are then collected from the mother.
