Q

How is fertility mainly improved for patients with PCOS?

A

Try to stimulate ovulation (ovulation induction) via development of one ovarian follicle (avoids multiple pregnancy)

Q

How does IVF work?

A

High dose of FSH to stimulate eggs
Prevent premature ovulation via GnRH agonist/antagonist
Give LH to allow egg maturation
Retrieve eggs from ovary
Fertilisation in vitro or intracytoplasmic injection of sperm
Embryo incubation
Embryo transfer

16
Q

How is premature LH surge prevented in IVF?

A

Via GnRH antagonist or GnRH agonist- if given GnRH in a non pulsatile way LH is inhibited

17
Q

How are eggs matured in IVF and where?

A

By giving LH then hCG-they should still be in the ovary

18
Q

What happens in egg maturation?

A

Egg goes from metaphase 1 to metaphase 2 to allow it to halve its DNA content

19
Q

How does Ovarian hyper stimulation syndrome occour?

A

Due to long lasting hCG during IVF

20
Q

How does Ovarian hyper stimulation syndrome present?

A

Pleural effusion
Ascites
Renal failure
Ovarian torsion

21
Q

What are methods of contraception?

A

Barrier: male / female condom/ diaphragm or cap with spermicide
Combined Oral Contraceptive Pill (OCP)
Progestogen-only Pill (POP)
Long Acting Reversible Contraception (LARC)
Emergency Contraception
Vasectomy
Female sterilisation

22
Q

What are positives of the OCP?

A 
Easy to take 
 Effective
 Doesn’t interrupt sex
 Can take several packets back to back and avoid withdrawal bleeds
 Reduce endometrial and ovarian cancer
23
Q

What are negatives of the OCP?

A

It can be difficult to remember
No protection against STIs
P450 Enzyme Inducers may reduce efficacy
Not the best choice during breast feeding

24
Q

What are side effects of the OCP?

A 
Spotting (bleeding in between periods)
 Nausea
 Sore breasts
 Changes in mood or libido 
 Feeling more hungry
25
Q

What are non contraceptive uses of the OCP?

A

Lighter/less painful periods

PCOS (reduces LH and hyperandrogenism)

26
Q

What is the progesterone only pill (mini pill)?

A

Works as OCP but less reliably inhibits ovulation
Often suitable if cant take oestrogen
Can be used when breastfeeding

27
Q

What are negatives of the mini pill?

A

Can be difficult to remember
No protection against STIs
Shorter acting – needs to be taken at the same time each day

28
Q

What are the common long acting reversible contraceptives (LARCs)?

A

IUD (copper coil)- decreases sperm survival
Intra uterine systems- secretes progesterone
Progestogen-only injectable contraceptives or subdermal implants

29
Q

What are the emergency contraceptives?

A

IUD

Emergency contraceptive pill (ellaOne in 5 days, Levonelle in 3 days- less effective)

30
Q

What are side effects of emergency contraception?

A

Headache, abdominal pain, nausea

31
Q

What should we consider when chosing contraception?

A

Risk of venous thromboembolism
Other conditions
Need for prevention of STIs
Concurrent medication

32
Q

What are risks of HRT?

A

Venous thrombo embolism- use transdermal oestrogens if this is the case
Hormone sensitive cancers (mainly endometrial but also breast and ovarian, especially if use is long term)
Cardiovascular disease
Small risk of stroke

33
Q

What must we give with oestrogen? Why?

A

Progesterone- to prevent endometrial cancer (presents with post menopausal bleeding)

34
Q

What are benefits of HRT?

A

Relief of symptoms

Less osteoporosis related fractures

35
Q

How is gender different to sex?

A

Gender- what you identify as

Sex- biological

36
Q

What is gender dysphoria

A

When gender non conforming causes depression

37
Q

What are treatments for supporting transgender males/females?

A

Men- Testosterone injections or gels, progesterone to surpress menstrual bleeding
Women- high dose oestrogen, reduce testosterone via GnRH agonists (desensitisation of HPG axis)

38
Q

What are treatments for supporting transgender males/females and gender non binary individuals?

A

Men- Testosterone injections or gels, progesterone to surpress menstrual bleeding
Women- high dose oestrogen, reduce testosterone via GnRH agonists (desensitisation of HPG axis)
