OBSTETRIC HISTORY AND EXAMINATION: THE BOOKING VISIT
In the UK, pregnant patients are seen at approximately 10
antenatal visits; the visits may either be conducted by a midwife
alone or be shared with an obstetrician. Care is individualised
depending on maternal age, past medical history and general
health, as well as any complications that develop as the pregnancy proceeds.
The booking (first) visit takes place at 8–12 weeks’ gestation.
The history
Take a complete medical history and record details of any previous pregnancies (Boxes 11.8–11.9). Establish the date of the
LMP (Box 11.10).
Past medical history
Ask about:
• all past medical and surgical events
• diseases that may be affected by pregnancy: for example,
asthma may improve during pregnancy while inflammatory
bowel disease may worsen postnatally
• diseases that cause an increased risk in pregnancy, such as
diabetes, cardiac disease or Systemic Lupus Erythematosus
(SLE).
Drug history
Ask about:
• prescribed medications
• over-the-counter drugs and ‘natural’ remedies
Find out at what gestation any drugs were taken. Check that
pregnant patients are taking 400 mg of folic acid daily until
12 weeks gestation to reduce the incidence of neural tube defects (some higher-risk patients need a higher dose of 5 mg, for
example, patients taking anti-epileptic medication or those with
pre-existing diabetes).
Family history
To explore possible inherited conditions, take a complete family
history of both the pregnant patient and the father (Boxes 11.11
and 11.12).

and liver (high vitamin A content). Domestic violence can start or
escalate in pregnancy and is associated with an increased risk of
maternal death. All patients must be seen alone (without their
partner) on at least one antenatal visit to allow this to be explored.
Occupational history
Ask the patient about their occupation and whether they plan to
continue it. Occupations involving exposure to ionising radiation
pose specific risks to the foetus or mother, so their job plan may
require modification for safety reasons. There is no definitive
evidence of a link between heavy work and preterm labour or
pre-eclampsia.
Examination sequence
• Calculate BMI (weight/height2).
• Obtain a midstream specimen of urine for microscopy, cul-
ture and sensitivities.
• Measure blood pressure.
• Do not perform a routine full physical examination (including
breast and vaginal examination) in healthy pregnant patients.
It is unnecessarily intrusive and has a low sensitivity for disease identification. However, you should perform a full examination, including cardiac auscultation, of any patient with
poor general health.

ROUTINE ANTENATAL CHECK IN LATER PREGNANCY
The history
Ask about:
• any new symptoms
• symptoms relevant to ongoing conditions unrelated to
pregnancy
• the mother’s perception of foetal movements.
Fetal movements are initially felt at 16–20 weeks’ gestation.
Their frequency increases until about 32 weeks to an average of
30 movements per hour, and this level remains unchanged until
delivery. The ‘classic’ fetal movement is a kick, but any perceived
fetal activity counts as movement. Movements may decrease if
the mother is given sedative drugs and may be felt less if the
placenta is anterior. They also may decrease with intrauterine
compromise, which may precede stillbirth.

https://t.me/med1917
Common presenting symptom s
Physiological symptoms
• Breast tenderness: often the earliest symptom of pregnancy
and may occur even before a missed period.
• Mild dyspnoea: may be due to increased respiratory drive
early in pregnancy or diaphragmatic compression by the
growing uterus late in pregnancy.
• Heartburn: gradually increases in prevalence, affecting up to
three-quarters of patients by the third trimester. It results from
relaxation of the gastro-oesophageal sphincter and acid
reflux.
• Constipation, urinary frequency, nausea and vomiting (which
usually resolve by 16–20 weeks).
• Aches and pains, especially backache, carpal tunnel syndrome and pubic symphyseal discomfort.
These physiological symptoms affect patients to different degrees and will occasionally merit examination and investigation to
exclude other problems. Secondary amenorrhoea is the most
obvious symptom of early pregnancy.
Reduced fetal movements
This is a common emergency presentation or reason for referral
to a hospital by a midwife, and merits a full history, examination
and fetal monitoring. It can be a sign of fetal compromise.
tract infection; less common causes include appendicitis, ovarian
cyst accidents, sickle cell crisis or inflammatory bowel disease. It
is critical to take a complete history of a pregnant patient with
abdominal pain and to perform a full obstetric and abdominal
examination, including renal angle palpation. This becomes more
difficult as pregnancy progresses, and the expanding uterus
makes palpation of other organs and masses difficult. Ultrasound
or MRI scanning may aid diagnosis.
Pre-eclampsia
Pre-eclampsia is a multifactorial syndrome comprised of high
blood pressure, proteinuria and placental compromise, and is a
significant cause of maternal and foetal morbidity. It is often
asymptomatic and detected by blood pressure monitoring and
urinalysis, although some patients develop generalised headaches and rapidly worsening peripheral oedema. A history
focused on headaches, worsening oedema and upper abdominal pain should be taken. The examination is that of a routine
antenatal assessment but should also include a check for
hyperreflexia and ankle clonus.
Pruritus
Pruritus (itching) affects one-quarter of pregnant patients. Rarely,
it is associated with liver cholestasis, in which case it is generalised, and there is no rash.
Vaginal bleeding in pregnancy
Vaginal bleeding in pregnancy before viability may herald a
miscarriage; after 24 weeks, it is called an antepartum haemorrhage. It can be a sign of a placental abruption, where the placenta
prematurely separates, or of a low-lying placenta. At term, light
vaginal bleeding can also be a sign of labour. Vaginal bleeding is
never considered normal in pregnancy and always merits hospital
review with a full history and examination. Painless bleeding is
more typical of local causes, such as a cervical polyp, or a lowlying placenta, whereas painful bleeding is more in keeping with
placental abruption. It is imperative to always consider venous
access and send blood for blood count and cross-matching in
any pregnant woman presenting with vaginal bleeding.
Abdominal pain
Abdominal pain is common in pregnancy. It can be caused by
benign physiological issues such as constipation and is also a
common presenting feature of labour when patients are contracting in established labour or tightening in early labour. It can
also be caused by polyhydramnios or placental abruption.
Any condition causing abdominal pain can present coincidentally in pregnancy, however. A common example is urinary
Breathlessness
Mild breathlessness is physiological in pregnancy. In rare circumstances, increased breathlessness is due to pulmonary
oedema in pre-eclampsia or exacerbation of heart disease. If
breathlessness is associated with chest pain, a pulmonary embolism (p. 85) should be considered. The chest should be
examined, and oxygen saturation and respiratory rate measured.
An electrocardiogram is helpful, and the risks/ benefits of
radiological imaging should be assessed. Consideration should
be given to an echocardiogram to exclude unknown congenital
or acquired heart disease (e.g. cardiomyopathy).
The physical examination
Examination sequence (Videos 23
and 23A)
• Before examining the patient, ask them to empty their
bladder (perform urinalysis). They should lie with their head on
a low pillow, with their abdomen exposed from the symphysis
pubis to the xiphisternum.
• Examine patients in late pregnancy in the left lateral position
or semirecumbent, 15 degrees to the horizontal, to avoid

vena cava compression, which can cause hypotension for the
mother and hypoxia for the foetus.
• Measure blood pressure.
• Note their general demeanour. Are they at ease or distressed
by physical pain?
• On inspection, look for signs of pregnancy, such as the linea
nigra (a dark discoloration of the midline of the abdominal
skin) and striae gravidarum (stretch marks).
• Look for any scars, particularly from a previous Caesarean
section. Note the swelling of the uterus arising from the pelvis
and any other swellings. You may also see fetal movements.
Uterine examination (Video 23B)
• Ask the patient to report any tenderness and observe their
facial and verbal responses constantly.
• Place the flat of your hand on the uterine swelling. Gently flex
your fingers to palpate the upper and lateral edges of its firm
mass. Note any tenderness, rebound or guarding outside the
uterus. Palpate lightly to avoid triggering myometrial
contraction, which makes fetal parts difficult to feel. Avoid
deep palpation of any tender areas of the uterus. Note any
contractions and any foetal movements.
• Face the patient’s head. Place both your hands on either side
of the fundus and feel the fetal parts. Estimate if the liquor
volume is normal. Assess how far from the surface the fetal
parts are. If you can feel them only on deep palpation, this
implies large amounts of fluid (Fig. 11.35A).
• With your right hand on the patient’s left side, feel down both
sides of the uterus. The fuller side suggests the location of the
fetal back (see Fig. 11.35B).
• Now face the patient’s feet. Place your hands on either side
of the uterus, with your left hand on the left side, and feel the
lower part of the uterus to try to identify the presenting part.

MALE REPRODUCTIVE SYSTEM
Anatomy and physiology
The male genitalia include the testes, epididymides and seminal
vesicles, penis, scrotum and prostate gland (Fig. 11.42).
The testes develop intra-abdominally near the kidneys and
migrate through the inguinal canal into the scrotum by birth. They
have their own blood, lymphatic and nerve supply, so testicular
problems may cause abdominal pain and enlargement of the
para-aortic lymph nodes. The scrotum is a pouch with thin,
pigmented, wrinkled skin that helps to regulate the temperature
of the testes (Fig. 11.43), as sperm production is most efficient
below body temperature. The left testis lies lower than the right.
Each testis is oval, 3.5–5 cm long, and covered by the tunica
albuginea, which forms the posterior wall of the tunica vaginalis.
This is a prolongation of the peritoneal tube that forms as the
testis descends during development. If it persists, it may be
associated with an indirect inguinal hernia sac or a congenital
hydrocoele. Along the posterior border of each testis is the
epididymis.
The testes produce sperm and testosterone, starting at puberty (10–15 years of age; see Fig. 15.19). Sperm mature in the
epididymis and pass down the vas deferens to the seminal
vesicles. They are ejaculated from the urethra, together with
prostatic and seminal vesicle fluid, at orgasm.
The penis has two cylinders of endothelium-lined spaces
surrounded by smooth muscle, the corpora cavernosa
(Fig. 11.44). These are bound with the bulbospongiosus surrounding the urethra, which expands into the glans penis. The
penile skin is reflected over the glans, forming the prepuce
(foreskin). Sexual arousal causes a parasympathetically mediated
increased blood flow into the corpora cavernosa with erection to
enable vaginal penetration. Continued stimulation causes
sympathetic-mediated contraction of the seminal vesicles and
prostate, closure of the bladder neck and ejaculation. Following
orgasm, a reduction in blood inflow causes detumescence.
The prostate and seminal vesicles contribute to seminal fluid.
After age 40, the prostate develops a trilobar structure because

of benign enlargement. Two lateral lobes and a variable median
lobe protrude into the bladder and may cause urethral and
bladder outflow obstruction. Prostate cancer develops in the
peripheral tissue of the lateral lobes and sometimes may be
detected by digital rectal examination. Only the posterior aspect
and the lateral lobes of the prostate can be felt by rectal examination (p. 111).
The history
Disorders of the male genitals may present as urinary symptoms,
genital or pelvic pain, genital swellings, sexual dysfunction or
infertility.
In addition to documenting the patient’s main genital or urinary
problems, be sure to ask about:
• the timescale of their development
• how they affect lifestyle and any sexual activity
• sexual function, if appropriate
• past conceptions or problems with fertility
• general urological symptoms:
• genital swelling
• genital or pelvic pain
• lower urinary tract symptoms
• urethral discharge.
Penile discharge or dysuria
Ask about:
• the duration of discharge or dysuria
• whether these are new or recurrent symptoms
• any other urinary symptoms
• the sexual history
• any systemic upset.
These symptoms usually represent urethritis which is the result
of either an STI or a urinary tract infection. They may precede and
lead to epididymo-orchitis (see later) or prostatitis. Prostatitis is
associated with pelvic, perineal or scrotal pain, fever and systemic upset in acute bacterial prostatitis, or may lead to chronic
pain and urinary symptoms in chronic prostatitis.
Scrotal swelling or pain
Patients often present acutely with scrotal pain and swelling
together; they may also, however, present with either symptom
alone.
Ask about:
• duration of the swelling
• whether it is unilateral or bilateral
• association with pain
• onset of pain: sudden or gradual
• character and duration of the pain
• radiation of the pain
• any history of trauma
• any associated symptoms:
• systemic upset (nausea, vomiting, fever or weight loss)
• urinary symptoms
• urethral discharge
• sexual history (see Box 11.5).
There are many causes of scrotal swelling or pain, but a patient with sudden-onset unilateral scrotal pain should be
considered to have testicular torsion until proven otherwise.
Testicular torsion occurs most commonly between the ages of
10 and 30 years and is very rare over the age of 40. Pain is
usually of acute onset and excruciating; it is not relieved by lying
still. It is often associated with nausea and vomiting but not
