Which organs are found in the pelvic cavity?
Ovaries
Uterine tubes
Uterus
Superior aspect of vagina
Which organs are found in the perineum?
Inferior aspect of vagina Perineal muscles Bartholins glands Clitoris Labia
What separates the pelvic cavity from the perineum?
Pelvic floor muscles - levator ani
What forms the floor of the peritoneal cavity & roof of the pelvic cavity?
Inferior parietal peritoneum
What are the 2 clinically relevent pouches in the women?
Vesicouterine pouch
Rectouterine pouch
What is the broad ligament & what does it contain?
Double layer of peritoneum that keeps the uterus in midline position
Contains the uterine tubes & proximal aspect of the round ligament
What are the 3 layers of the uterus?
Perimetrium
Myometrium
Endometrium
What is the most common position of the uterus?
Antiverted - cervix tipped anterior to vagina
Antiflexed - uterus tipped anterior to cervix
Where does fertilisation occur
Ampulla
What is the connection between the pelvic cavity & peritoneal cavity
Fimbrae open into the peritoneal cavity
Which organ is the primary female reproductive organ
Ovaries
What is the role of the ovaries?
Secrete oestrogen & progesterone
Release ovum
What is the role of the levator ani muscle?
Tonic contraction - supports organs
Reflexively contracts further if intra-abdo pressure increases
What is the innervation of levator ani
S2,3,4 & S3,4,5
Which nerve innervates the peroneum
Pudendal nerve
What is the perineal body
A centre of collagen & elastin where the muscles of the perineum attach
What is the fornix?
The point at which the cervix holds the walls of the vagina apart
Anterior
Posterior
2 Lateral
What is the histological organisation of the ovaries?
Cortex - Tunica albuginea & germinal epithelium (cuboidal)
Medulla - helocrine arteries
What condition would be seen with low testosterone & high GnRH
Primary gonadal failure
What is the role of GnRH
It is secreted from the hypothalamus & stimulates the anterior pituitary to release LH & FSH
What is the role of FSH individually?
Stimulates follicular growth
What is the role of LH individually?
Stimulates further follicle development (production of the corpus luteum_
What is the role of LH & FSH together?
Stimulate the ovarian follicles to secrete oestrogen
What is the role of progesterone & oestrogen?
Prepare and maintain the endometrium for implantation
How is heavy menstrual bleeding (with no pathological cause) treated medically?
Mirena coil
Tranexamic acid
COC
Norethisterone
DMPA
Surgery
What are the causes of heavy menstrual bleeding?
Fibroids Polyps Adenomyosis Coagulopathy Malignancy
What are premenstrual disorders?
premenstrual symptoms that have an impact on daily life
Physical, emotional & behavioural symptoms
How is premenstrual disorder diagnosed?
Symptom diary over a minimum of 2 cycles
What are the medical treatments of premenstrual disorder?
Ovulation suppression
- Combined oral contraception
- GnRH agonist - 6 month max
- Surgery
What are the main indications for an endometrial biopsy?
Abnormal uterine bleeding Infertility Miscarriage Assess response to hormone therapy Endometrial ablation Cancer screening Pre-hysterectomy work up Incidental thickening seen on scan
What are the main forms of combined hormonal contraception?
Pill
Vaginal Ring
Patch
How does CHC work?
Stops ovulation via release of oestrogen & progesterone
What are the main risks associated with CHC?
VTE
Arterial disease
Breast & cervical cancer
How does Desogestrel work?
POP - inhibits ovulation via progesterone release
When is the progesterone only pill contraindicated?
In patients with breast cancer
Why is the progesterone only pill used in epileptics
anti-epileptic drugs are usually enzyme inducers which effect the efficacy of CHC
POP is not affected by enzyme inducers
