The principal modes are growth within the uterine wall, towards the cavity, and towards the outer surface: intramural uterine fibroids, submucosal uterine fibroids and subserosal uterine fibroids. “Fibrous tumour” is the historical label; the usual modern lesion is a leiomyoma, a benign growth of smooth muscle with a variable connective-tissue component, rather than a mass of collagen alone.[ref]
An intramural uterine fibroid enlarges within the myometrium. It can remain enclosed by uterine muscle, push the cavity aside, or expand both inner and outer contours. Several nodules can give an irregularly enlarged uterus. Expansion compresses surrounding tissue into a cleavage plane or pseudocapsule; this differs from the destructive infiltrative growth typical of a malignant lesion.
A submucosal uterine fibroid grows towards the endometrium, projecting into and distorting the uterine cavity. It may remain broad-based or acquire a stalk as the surrounding wall is displaced. A pedunculated uterine fibroid can be pushed through the cervical canal and appear in the vagina as a uterine polyp. A polyp formed in this way is a mode of presentation of the same smooth-muscle tumour, not necessarily a different histological species. Its relation to the cavity helps explain why a comparatively small lesion may be associated with substantial bleeding.
A subserosal uterine fibroid projects outwards beneath the serosal covering. It may have a broad attachment or a long pedicle and become a large extrauterine-looking mass. Lateral outward growth can extend between the layers of the broad ligament; cervical growth can displace neighbouring pelvic structures. Rarely, a detached pedunculated lesion gains a blood supply from adjacent tissues and persists as a parasitic growth; this is not ordinary distant metastasis.[ref]
The three directions are not mutually exclusive: a large nodule may affect both the uterine cavity and its external surface. Modern location classifications describe its relation to endometrium, myometrium and serosa more precisely, but those later type numbers are unnecessary to explain the anatomical modes requested here.
Growth is also distinct from secondary change. A poorly supplied area can undergo hyaline or cystic degeneration, haemorrhagic change or calcification; these changes alter consistency without establishing a new malignant mode of growth. Uterine fibroids often respond to the reproductive hormonal environment and commonly shrink after menopause, but neither every lesion's course nor its rate of growth is identical.[ref] Location and attachment describe the mode of expansion; tissue examination establishes the nature of the tumour.
Classify the bleeding by anatomical source and by its relation to pregnancy, childbirth and menstruation; treatment must address that source. The amount of visible genital haemorrhage does not measure all the loss: a ruptured ectopic pregnancy or concealed placental abruption can cause major internal blood loss. Initial assessment of severe bleeding concerns the circulation, anaemia and the need for resuscitation while the cause is established. Bleeding from the urethra or rectum must first be distinguished from genital bleeding.
Local sources outside the uterine cavity. The vulva and vagina may bleed from lacerations after childbirth or other trauma, an inflamed lesion, a foreign body, a vascular lesion or cancer. Examination localizes the loss; treatment is local compression and repair of a significant laceration, removal of the foreign body, cause-directed treatment of infection, or specialist management of the lesion. A cervical polyp, cervical ectropion, cervicitis or cervical cancer can cause bleeding from the cervix, often noticed between periods or after intercourse. A suitable polyp can be removed and examined; inflammation requires its cause to be established, while a suspicious lesion requires diagnostic assessment rather than indiscriminate cauterization. After menopause, thin, fragile vulvovaginal tissues can also bleed; this does not remove the need to investigate a suspicious lesion. These are different conditions, not one disease called “uterine haemorrhage”. [ref]
Bleeding from the endometrium. Heavy or irregular menstruation may accompany ovulatory dysfunction, uterine fibroids, endometrial polyps, adenomyosis, a coagulopathy, medication effects or endometrial cancer. Modern assessment includes the menstrual and drug history, a full blood count, and selected ultrasound, hysteroscopy or tissue sampling according to the suspected cause. Where appropriate, menstrual bleeding can be reduced with tranexamic acid or hormonal treatment; an intracavitary polyp or uterine fibroid may instead need targeted removal. Persistent postmenopausal bleeding must not simply be treated as an ordinary period. [ref]
Early pregnancy. A miscarriage may bleed while pregnancy tissue separates or remains in the uterus. In a stable, confirmed case, expectant, medical or surgical management may be appropriate; heavy continuing loss or infection changes the urgency. Ectopic pregnancy requires a separate plan: selected stable cases may be monitored or treated medically, but rupture with haemorrhagic collapse requires urgent operative control, not treatment of the vagina as though it were the principal source. A hydatidiform mole is another pregnancy-related source of abnormal bleeding; current management includes removal by suction evacuation and subsequent human chorionic gonadotropin surveillance for persistent disease. [ref] [ref] [ref]
Later pregnancy and labour. Placenta praevia commonly produces relatively painless bleeding, whereas placental abruption more often causes pain and uterine tenderness; these are useful patterns, not infallible rules. Management depends on the mother's circulation, the fetus, the placental lesion and the stage of pregnancy, with urgent delivery when required. A blind digital cervical examination is inappropriate before a possible placenta praevia has been excluded. Ruptured vasa praevia causes fetal rather than maternal bleeding and demands a different interpretation. A small blood-stained mucous “show” during cervical change is not equivalent to these pathological losses. [ref] [ref]
After delivery. The principal categories are failure of uterine contraction, retained placental tissue, trauma and disordered coagulation. For uterine atony, the aim is to restore contraction with uterine massage and an appropriate uterotonic. Retained tissue, a genital laceration or uterine inversion requires correction of that particular cause; a coagulopathy requires haemostatic support. With placenta accreta spectrum, attempted forcible separation can provoke severe haemorrhage. Current care combines resuscitation with cause-directed measures, and can require tranexamic acid, balloon tamponade, embolisation or surgery when initial measures fail. Later postpartum bleeding also raises retained tissue and endometritis. [ref]
The 1865 distinction. An answer of the period could distinguish menstrual loss, local lesions, pregnancy-related haemorrhage and post-delivery failure of contraction through the history and physical examination. Compression, local plugging, removal of an accessible lesion and obstetric intervention were among the available approaches; their use was debated. The 1864 discussion of placenta praevia documents such disagreement. Modern imaging, blood banking, the present drug regimens and current operative pathways must not be attributed to that practice. Nor should historical astringents or depletion be substituted for identifying the source. [ref]
Seek evidence of penetration and evidence bearing on violence separately; neither a finding nor its absence can by itself determine consent or establish the whole felony. Twelve hours is a reason to examine and preserve evidence promptly, not a guarantee that diagnostic traces will be present.
For the historical legal element, use the original Offences against the Person Act 1861. Section 63 made carnal knowledge complete upon proof of penetration without requiring proof of emission of seed. Thus absence of semen cannot defeat proof of the penetration element, while the presence of semen does not by itself establish that element or identify an offence. Section 48 treated rape as a felony; §63 specifies the narrower evidential point asked about here.[ref]
Obtain permission for the examination and each specimen, record the account in the woman's own terms, and note the reported timing, pain, bleeding, washing and changes of clothes. Ask about other recent sexual contact only insofar as it affects interpretation of a trace. Record observations independently of the allegation, preserving clothing and samples with their identities and collection sites. A medical examination should also address injuries and health needs; its purpose is not merely production of evidence.
For evidence of recent penetration, inspect the vulva, vaginal entrance and, where appropriate, the vagina for fresh abrasions, bruising, tears, swelling, tenderness or bleeding. Describe the location and appearance rather than calling an injury a “rape mark”. Collect any relevant fluid and stained clothing. An 1866 examination could use microscopy to look for sperm; modern analysis may add validated semen tests and DNA profiling. Neither retained sperm nor an injury can precisely date the event to twelve hours previously or prove who performed it without additional evidence. Conversely, washing, lack of ejaculation or loss of a sample may leave no detectable trace.[ref]
Do not infer prior sexual history from vaginal laxity or the appearance of the hymen. A fresh injury can be documented, but an uninjured or previously altered hymen cannot prove or disprove the particular alleged penetration. Current authoritative guidance expressly rejects “virginity testing” as a scientifically valid inference about intercourse.[ref]
For evidence bearing on force and non-consent, examine the whole body for abrasions, bruises, torn clothing, restraint marks and injuries of the thighs, wrists, arms, face or neck. Record any account of threats, overpowering, loss of consciousness or inability to resist. Injuries may corroborate an account of violence, but can have other causes; their absence does not establish agreement. A frightened or incapacitated person may not struggle, and penetration can occur without visible injury. Even apparently precise examination findings must be interpreted alongside the history and other evidence.[ref]
Some nineteenth-century medico-legal writing demanded continuing resistance as evidence of non-consent. That was a historical assumption, not a biological test of whether consent was withheld.[ref] The medical witness should state what was observed and how strongly it supports the account; the tribunal determines the legal conclusion. No universal combination of semen, hymenal findings and bruises can “legally establish” all the elements from the examination alone.
Recurrent bleeding in the second half of pregnancy particularly suggests placenta praevia, but placental abruption, vasa praevia, labour and local disease must also be considered. Treatment depends on the source, severity, maternal condition, fetal condition and gestational age.
The source's “last half” includes a wider interval than the definition of antepartum haemorrhage from 24 weeks used by the cited British guideline. No diagnosis follows from intermittency alone.
In placenta praevia, the placenta covers the internal opening of the cervix. Development of the lower uterine segment and opening of the cervix disturb attachment at the placental margin, exposing maternal vessels. Bleeding is often painless and recurrent and can become severe after apparently minor episodes. In placental abruption, a normally situated placenta separates prematurely. Bleeding into the placental bed reduces exchange with the fetus; pain, tenderness and increased tone of the uterus are suggestive, but their absence does not exclude it. Some blood can remain concealed, making visible vaginal loss a poor measure of total loss.
In vasa praevia, vulnerable fetal vessels run through the membranes near the internal cervical opening. Rupture, particularly when the membranes break, can cause rapid fetal blood loss while the mother remains comparatively stable. Other causes include a blood-stained cervical “show” in labour, cervical ectropion, a cervical polyp, local infection, trauma, and occasionally a tumour of the cervix or vagina. These must be distinguished from placental bleeding rather than presumed harmless from a small volume alone.[ref]
For an 1867 answer, the classic contrast is between “unavoidable” haemorrhage from placenta praevia and “accidental” haemorrhage from premature separation of a normally implanted placenta. The adjectives are historical classifications, not claims that either outcome is inevitable or that every placental abruption follows an accident. Period management sought to conserve maternal strength when slight bleeding settled, then accomplish delivery when recurrent loss or labour made waiting dangerous. For partial placenta praevia, rupture of membranes was used in suitable labour to bring the presenting part down against the bleeding region. For more extensive placenta praevia, vaginal plugging, dilation and turning to deliver the child were debated and used. Contemporary discussion shows disagreement about how long it was safe to temporise: an 1864 report describes both advocates of early delivery and arguments about plugs, dilating bags and turning.[ref]
Those measures belong to the history of managing haemorrhage before modern operative safety, imaging and transfusion services. They must not be carried over as a modern algorithm: a vaginal plug can conceal continuing loss; attempted separation of the placenta or turning through placenta praevia can aggravate bleeding and endanger the fetus.
In current practice, the initial response to significant bleeding is hospital assessment with maternal resuscitation, monitoring, intravenous access and blood tests, with blood products available according to severity. Determine placental position by ultrasonography, assess the fetus according to gestational age, and look for local causes with appropriate examination. Do not perform a digital vaginal examination while placenta praevia remains a possible explanation until it has been excluded by ultrasonography. A carefully performed speculum examination and a skilled transvaginal ultrasound are different procedures; the latter is a safe, useful way to locate the placental edge. A normal ultrasound does not exclude placental abruption.[ref]
During the later preterm months, a stable mother and fetus after bleeding has stopped may be managed expectantly under specialist supervision. The plan includes surveillance, correction of anaemia, readiness to return urgently, and individual decisions about admission and timing of birth. Corticosteroids are considered when preterm delivery is likely; they do not treat the bleeding. Ongoing major haemorrhage, maternal instability or serious fetal compromise can require delivery regardless of immaturity. This is not a policy of waiting for full term at any cost.
At or near term, the cause determines the route. Persistent placenta praevia covering the internal cervical opening requires caesarean birth; repeated bleeding may require earlier delivery. Current 2026 guidance individualises timing for uncomplicated low-lying placenta or placenta praevia and advises considering planned birth no later than 37 weeks and 6 days. A low-lying placental edge that does not cover the opening requires individual assessment of whether vaginal birth is appropriate. These timings are present guidance, not an 1867 rule.[ref]
With placental abruption, expedite delivery when indicated by maternal or fetal condition; caesarean birth is often required for a live compromised fetus when vaginal delivery is not imminent, while vaginal delivery may be appropriate in other circumstances. A local cervical lesion requires cause-specific management. Suspected rupture of vasa praevia is an emergency for urgent caesarean birth and neonatal resuscitation; an antenatally detected vasa praevia calls for planned birth before labour or membrane rupture.[ref] The central distinction is therefore safe observation of a settled, stable preterm episode versus timely delivery for an ongoing hazard, not a single remedy for every late-pregnancy bleed.
