female examination
• Weight
• Height
• BMI (kg/m2)
• Fat and hair distribution
o Hirsutism – increased testosterone (BAH)
• Galactorrhoea
o Increased prolactin impairs release of egg
• Abdominal examination
o Do not advocate this, usually do USS first.
• Pelvic examination
o
Male examination
• Weight
• Height
• BMI (kg/m2)
• Fat and hair distribution
o Hypoandrogenism – a loss of libido, impotence, infertility, shrinkage of the testicles, penis, and prostate, diminished masculinization (decreased facial and body hair growth)
o Do you shave regularly?
o Gynaecomastia
♣ Klinefelter syndrome (hypogonadism & microorchidism – infertility)
• Abdominal and inguinal examination
• Genital examination
o Testes
♣ Cryptorchidism
• Hypospadias
• Testicular tumours (orchiopexy before puberty lower risk compared to after puberty)
• Reduced fertility even after orchiopexy
o Epididymis
♣ Epididymitis
• STDs – Chlamydia trachomatis, gonorrhoea
• NSTD
o Vas deferens
♣ CF patients & congenital bilateral absence of the vas deferens (CBAVD)
o Varicocele
o Penis – hypospadias
when to refer?
•
NICE guidelines – 1 year after trying • Unless there’s a problem o Period irregularity o Past medical history o Testicular problems • Abnormal tests • HIV/Hep B • Anxiety • Age o <35yrs (after 1year) o 35 - 45yrs (after 6 months) o >45 yrs (little can be offered) • Baseline investigations o Female: ♣ Rubella immunity ♣ Chlamydia – affects fallopian tubes ♣ TSH ♣ If periods are regular: • Mid luteal progesterone ( 7 days prior to expected period); ♣ If periods are irregular: • Do day 1-5 FSH, LH, PRL, TSH, testosterone o Male: ♣ Semen analysis
investigations
o Tubal patency test
PCOS
1) Androgen excess o Clinical (Hirsutism) o Biochemical (Testosterone) 2) Infrequent periods o Anovulation 3) Polycystic ovaries o Ultrasound shows classic necklace pattern • Management: o Treat underlying cause o Weight loss/gain ♣ BMI >18 and <35 ♣ High BMI common cause of anovulation • Note NHS does not treat individuals with BMI >30 o
Ovulation Induction
♣ Clomiphene
♣ Gonadotrophins injections
Ovarian hyperstimulation syndrome:
- OHSS is divided into the categories mild, moderate, severe, and critical.
- In mild forms of OHSS the ovaries are enlarged (5–12 cm) and there may be additional accumulation of ascites with mild abdominal distension, abdominal pain, nausea, and diarrhoea.
- In severe forms of OHSS there may be haemoconcentration, thrombosis, distension, oliguria (decreased urine production), pleural effusion, and respiratory distress.
- It may occur after stimulation of the ovaries into superovulation with drugs such as hCG and human menopausal gonadotrophin. It is rare with Clomifene except in polycystic ovarian syndrome (PCOS).
Male factors
• Investigations for azoospermia: o History & Examination o FSH, LH, Testosterone, Karyotype, PRL o CF screen – CBAVD • Hypo-gonadism: give gonadotrophins • Hyper-gonadotrophic: FSH high, LH high, testicle size small. Seen commonly in Klinefelter
Sexual problems • Psychosexual counselling o Onward referral • Artificial insemination o Timed insemination at home o Intra-uterine insemination at clinic
