[Part 5]-B11- hormonal coordination 🫥🚺🚹 Flashcards
How do hormonal contraceptives such as: an implant, skin patch or injection work ?
- hormonal contraceptives [such as: an implant, skin patch or injection] contain the hormone progesterone.
RECAP: How does progesterone stop eggs from being matured or released ?
- progesterone, stops eggs from being matured or released because, it stops the pituitary gland, from releasing more follicle stimulating hormone [FSH].
- ; progesterone, also inhibits the release of luteinising hormone [LH]-preventing more eggs from maturing, or being released.
How is the hormone, in a contraceptive implant delivered ?
- the contraceptive implant, is a tiny tube that’s inserted under the skin, that slowly releases progesterone.
How is the hormone, in a contraceptive injection delivered ?
- the contraceptive injection, contains progesterone which lasts for 12 weeks.
How is the hormone, in a contraceptive patch delivered ?
- the contraceptive patch contains a mixture of two hormones, which is stuck to the skin and replaced every seven days.
What are the advantages and disadvantages, of hormonal contraceptives ?
- advantage- the contraceptive implant lasts for 3 years, and is 99.95% effective.
- disadvantage- ; these hormonal forms of contraception, can have side effects such as: weight gain, acne, changes in blood pressure and potential mood changes [could also take place.]
What’s another disadvantage, of hormonal contraceptives ?
- disadvantage- like the pill, hormonal contraceptives don’t protect against sexually transmitted infections [STI], such as HIV
How do barrier methods work ?
- barrier methods such as a condom or a diaphragm, prevents the sperm from reaching an egg [and fertilising it- barrier methods prevent fertilisation].
How do condoms and diaphragms, work?
- This is because, a condom is a thin latex sheath that goes over the penis before intercourse, to collect sperm
- and a diaphragm, is a rubber diaphragm placed over the cervix, before intercourse. [and it’s initially fitted by a doctor]
What are the advantages and disadvantages of barrier methods ?
- advantage- if used correctly they’re an effective form of contraception because, condoms can reduce the risk of STIs.
- disadvantage- ; condoms can get damaged, and let sperm through
Fill in the gaps: both condoms and a diaphragm are ____ effective, if they’re used with a __________ gel.
- both condoms and a diaphragm are more effective, if they’re used with a spermicide gel.
What are some other advantages and disadvantages, of barrier methods ?
- advantage- since they don’t use hormones, there aren’t any side effects such as: changes in blood pressure
- disadvantage- but if a diaphragm isn’t fitted correctly, sperm can get past
What are spermicides ?
- spermicides, are chemicals that kill or disable sperm, reducing the chances of fertilisation
- ; they’re readily available, but not very effective.
What’s a IUD ?
- also known as an intrauterine device or the coil, an IUD is a small structure inserted in the uterus [by a doctor], which prevents an embryo from implanting.
What’s a IUD ?
- also known as an intrauterine device or the coil, an IUD is a small structure inserted in the uterus [by a doctor], which prevents an embryo from implanting.
- [there are two types of IUD’s: copper and plastic IUD’s- which release progesterone]
