Chronic pelvic pain
Infertility
Ectopic pregnancy
Fitz-Hugh-Curtis Syndrome?
upper quadrant pain (inflammation of liver capsule or diaphragm from spread of infection from pelvic inflammatory disease)
What is a hydrosalpinx?
Distally blocked fallopian tube filled with serous/clear fluid
Group I ovulatory disorders?
Hypothalamic
amenorrhea-includes stress, excessive exercise, anorexia, Kallman’s syndrome, isolated gonadotropin deficiency
Findings of group I ovulatory disorders
Low FSH, estrogen, normal prolactin, negative progesterone challenge
Group II hypothalamic pituitary dysfunction
Normogonadotrophic-normoestrogenic anovulation
e.g. PCOS
Group III ovulatory disorders
Ovarian failure
-high gonadotrophins with low estrogens
Which type of ovulatory disorder is PCOS?
Type II (hypothalamic-pituitary dysfunction)
Hysterosalpingogram
x-ray that examines the uterus and the fallopian tubes and the surrounding area
Commonest cause of anovulatory infertility?
Polycystic ovary syndrome
Increased ovarian volume?
> 10ml
How many follicles in PCOS?
More than 12 (between 2-8mm)
Diagnosis of PCOS (Rotterdam criteria)
-Irregular menstrual cycle, hirsutism, acne, subfertility, alopecia, obesity, acanthosis nigricans Biochemical: day 2 - day 5 -elevated serum LH (>10IU/L) -LH/FSH ratio >2 -normal estradiol -low progesterone -normal or mildly elevated prolactin -raised testosterone/FAI/A4
LH/FSH ratio in PCOS?
LH/FSH ratio >2
Serum LH in PCOS?
Elevated serum LH (>10IU/L)
Estradiol in PCOS?
Normal
Progesterone in PCOS?
Low
Testosterone in PCOS?
Raised
Clomifene citrate
Tamoxifen
Antioestrogens
Letrozole
Aromatase inhibitors
Ovulation induction: first line of treatment
Antioestrogens: clomifene citrate
Tamoxifen
Aromatase inhibitors: letrozole
How do you clomifene citrate (anti-oestrogens)
Monitor with tracking scan and serum progesterone
When do you give clomifene citrate?
Day 2- day 6 for 5 days
When do you give tamoxifen?
Day 2-6 for five days
Adverse effect of tamoxifen?
Estrogenic effect on endometrium
First line treatment for PCOS?
Anti-oestrogens: Clomifene citrate/tamoxifen
Aromatase inhibitors: Letrozole
Second line treatment for PCOS?
1) clomifene citrate + metformin
2) Gonadotropin therapy: daily injections (FHS and LH etc)
3) Laparoscopic ovarian diathermy
Investigating semen in men?
Semen analysis: twice over six weeks apart
- If abnormal, do an endocrine profile
- if SEVERELY abnormal –> do endocrine profile AND chromosome analysis and screen for cystic fibrosis, testicular biopsy
Most common cause of male infertility?
Idiopathic
Vasectomy, infection (e.g. chlamydia/gonorrhoea), congenital absence of vas deferens (e,.g. cystic fibrosis)
Obstructive causes of male infertility
Undescended testis, orchitis (e.g. mumps), torion/trauma, chromosomal (e.g. Klinefelter’s syndrome) Kartagener syndrome, Y chromsome micro deletions
Non-obstructive causes
Hormonal causes of infertility?
Hypogonadotrophic hypogonadism
Hypothyroidism
Hyperprolactinemia
PESA
percutaneous epididymal sperm aspiration
-you can also do percutaneous testicular sperm aspiration
(both you put a needle in to take out the sperm)
MESA
Microsurgical epididymal sperm aspiration
When do you do hysterosalpingogram/laparoscopy & dye?
In the first 10 days of cycle
-be careful in obesoty, previous pelvic surgery and Crohn’s disease
Salpingitis isthmica nodosa?
Diverticulosis of the fallopian tube = nodular thickening of the narrow part of the uterine tube due to inflammation
Fibroids
Non-cancerous growths in the uterus
Treatment of tubal disease
Tubal surgery
Selective salpingiogrpahy and catheterisation
In-vitro fertilisation
How many times should you have sex?
2-3 times a week
How much alcohol should women drink?
Limit to 4 units per week
Optimal weight for fertility?
19-29
Folic acid for fertility?
0.4mg/day preconception till 12 weeks gestation
When would you do hysteroscopy?
Only performed in cases where suspected or known endometrial pathology: i.e. uterine septum, adhesions, polyp
When would you do pelvic ultrasound?
perform when abnormality on pelvic examination: e.g. enlarged uterus/adnexal mass
when required from other investigations: e.g. possible polyp seen at HSG
What is endometriosis?
Presence of endometrial glands outside the uterine cavity
Symptoms of endometriosis
dysmenorrhoea, dysparenuia, menorrhagia, painful defaecation, chronic pelvic pain (severity of pain may be disproportionate to extent of disease)
Why does endometriosis affect fertility?
Reasons impaired infertility: anatomical damage (tubo-ovarian adhesions), dyspareunia, altered peritoneum environment (cytotoxic factors: impaired ovulation, lower embryo quality and impaired implantation)
Treatment for endometriosis?
Medical: combined oral contraceptive pill, progesterones (medroxyprogesterone acetate), GnRH agonists (zoladex +/- add back HRT)
Surgical : Laparoscopic ablation/resection and adhesiolysis of mild disease
Radical resection of severe endometriosis
Drainage and ablation cyst base for endometriomas (consider prior to IVF)

Treatment of premature menopause
Counselling Fertility: oocyte donation Prevention osteoporosis (OCP, HRT Cryopreservation of ovarian tissue (prior to radiotherapy or chemotherapy)
