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 specic risks to the foetus or mother, so their job plan may require modication for safety reasons. There is no denitive 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 identication. 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:

pregnancy
the mothers perception of foetal movements.
Fetal movements are initially felt at 16–20 weeksgestation. Their frequency increases until about 32 weeks to an average of 30 movements per hour, and this level remains unchanged until delivery. The classicfetal 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.

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 reux.
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 inammatory 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 difcult as pregnancy progresses, and the expanding uterus makes palpation of other organs and masses difcult. 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 signicant 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 hyperreexia 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/ benets 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 at of your hand on the uterine swelling. Gently ex
your ngers to palpate the upper and lateral edges of its rm mass. Note any tenderness, rebound or guarding outside the uterus. Palpate lightly to avoid triggering myometrial contraction, which makes fetal parts difcult 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 uid (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. Ballott the head by pushing it gently from one side to the other and feel its hardness move between your ngers (see
Fig. 11.35C).
The size of the uterus increases as pregnancy advances
(Fig. 11.36). At 20 weeks, the uterine fundus is at the umbi­licus; by 36 weeks, it reaches the xiphisternum. The distance

from the pubic symphysis to the top of the uterine fu ndus is the symphyseal fundal height (SFH). In a singleton preg­nancy, if the ba by is growing well, the SFH in c entimet res approximates the duration of pregnancy i n weeks. In multiple pregnancies, the fund us will measure larger at each stage. After 20 weeks, mea sure the SFH in centi­metres. With a tape measure, x the end at the high est point on the fundus (not always in the midline) and measure to the top of the symphysis pubis. To avoid bias, place the blank side of the tape facing you, lift the tape and read the measurement on the other sid e. The SFH is measured at every vi sit and recorded on a SFH centile chart in the maternal handheld record. In tall or thin patients, the SFH may be smaller than expected; in obese patients, it may be larger. After 25 weeks gestation, a difference of 3 or m ore

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 efcient 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 uid, 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 reected over the glans, forming the prepuce
(foreskin). Sexual arousal causes a parasympathetically mediated increased blood ow 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 inow causes detumescence.
The prostate and seminal vesicles contribute to seminal uid.
After age 40, the prostate develops a trilobar structure because

There may be associated systemic upset or clinical signs associated with urological disease; a complete history and ex­amination are therefore important.

of benign enlargement. Two lateral lobes and a variable median lobe protrude into the bladder and may cause urethral and bladder outow 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 patients 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 usually fever, lower urinary tract symptoms or urethral discharge.

264 THE REPRODUCTIVE SYSTEM
https://t.me/medicina_free
Epidydimal cyst
Fig. 11.45 Swellings of the scrotum.
Epididymo-orchitis is the most common differential diagnosis. The pain of epididymo-orchitis is often more insidious in onset compared to testicular torsion, and the patient may report a dull ache initially. There may be associated fevers, dysuria or urethral discharge, suggesting underlying STI or urinary tract infection. The discomfort is often worse when standing or moving around and may be relieved when lying still. On examination, it is usually possible to distinguish the tender, inamed epididymis from the adjacent testis. If testicular torsion cannot be excluded on history and examination, urgent testicular exploration is warranted, as torsion will cause loss of a testis if not relieved within 4–6 hours. While an ultrasound examination may be used to conrm a diagnosis of epididymo-orchitis, it should never be requested to assess for torsion.
Other scrotal swellings include hernias, varicocoele, hydro­coele, epididymal cysts and testicular tumours. These are usually painless, although vague or constant dull aches may be described (Fig. 11.45). Examination ndings can usually differ­entiate these diagnoses (Box 11.14).

persistent phimosis. This may produce balanitis (recurrent infection of the glans penis), posthitis (infection of the prepuce) or both (balanoposthitis).
If a tight foreskin is retracted and is not replaced, swelling and pain ensue, resulting in paraphimosis due to the tight preputial band (Fig. 11.46).
Dermatological conditions and drug reactions may affect the genital skin. Painful genital ulcers are usually caused by herpes simplex; painless ulcers occur in reactive arthritis (p. 293), lichen simplex and (rarely) syphilis. Genital warts may also be present, as well as penile carcinoma.
Penile skin lesions
Ask about:
location, duration and progression of the lesion
any pain
any problem retracting the prepuce
any associated systemic upset
any urinary symptoms
any history of dermatological disease
sexual history.
The inability to retract the foreskin (phimosis) is a common symptom in the urology clinic. Phimosis may be normal, 95% of babies are born with a non-retractile prepuce, but this usually resolves by the age of 16 years, when only 1% of boys have
Erectile dysfunction
Erectile dysfunction (ED) is the consistent or recurrent inability to attain and/or maintain a penile erection sufcient for penetrative intercourse.
Clarify from the history:
Is the problem failure to gain or maintain an erection, painful erection, penile deformity on erection or a combination of these?
How long has ED been a problem?
Has the patient ever been able to gain a rigid erection?
Do they ever have morning erections on waking?
Are they able to gain an erection under any circumstances,
such as masturbation?
Do their problems prevent penetrative intercourse?
