Sexual health statistics for England

‘Sexual and reproductive health’ covers a broad range of health matters, from sexually transmitted infections (STIs) and contraception to relationships and conception. It is an important aspect of the overall health and wellbeing of both individuals and communities.

This briefing covers sexual health statistics while a separate Commons Library briefing focuses on reproductive health statistics for England.

Poor sexual health can have numerous consequences, including unplanned pregnancies and abortions, as well as the transmission of STIs and HIV.

The most recent sexual health strategy, ‘A Framework for Sexual Health Improvement in England’, was published by the Department of Health in March 2013. It set an ambition to “improve the sexual health of the whole population”. There have been calls from select committees and other stakeholders for the government to produce a new strategy, though this has not yet occurred.

Commissioning sexual health services

In England, sexual health services are part of public health. This means that most ‘open access’ services (where people can use any sexual health clinic, in any area) are commissioned by local authorities.. Responsibility for commissioning more specialised sexual health services, such as HIV treatment and care, is split between NHS England and integrated care systems (ICSs).

In 2025, there were 4.5 million consultations delivered by sexual health services in England. The number of consultations increased year-on-year between 2016 and 2023, apart from a slight dip in 2020 due to service restrictions during the covid-19 pandemic. Figures peaked at 4.6 million in 2023 but have since fallen. The scaling up of online and telephone service provision contributed to the increase but the number of online consultations has decreased in the last year, while the number of face-to-face consultations has increased.

Spending on local authority-funded sexual health services in England has reduced in real terms from £859 million in 2013/14, when responsibility for public health was transferred from the NHS to local authorities, to £586 million in 2024/25.

Sexually transmitted infections (STIs)

Sexually transmitted infections (STIs) are diseases, caused by bacteria, viruses, and parasites, that can be passed from one person to another through condomless sexual contact with an infected partner. Some STIs can also be transmitted to a baby during pregnancy, childbirth and breastfeeding. Other routes of transmission include sharing needles.

The prevention, diagnosis and treatment of STIs is vital to stop their onward transmission and to prevent the development of long-term health problems from undiagnosed and untreated STIs.

The chart below shows trends in the number of sexual health screens – diagnostic tests for chlamydia, gonorrhoea, syphilis or HIV – and new STI diagnoses since 2015. In 2025, 2.4 million sexual health screens were carried out and around 402,000 new STIs were diagnosed.

The pandemic disrupted sexual health screens and diagnoses, meaning there were fewer in 2020 and 2021 than in previous years, although numbers have since recovered.

Data on STI diagnosis indicates that young people; gay, bisexual and other men who have sex with men; and people from Black Caribbean ethnic backgrounds have disproportionately high rates of certain STIs.

The most commonly diagnosed STIs in 2025 were chlamydia (45% of all new STI diagnoses), gonorrhoea (19%), first episode genital herpes (9%) and first episode genital warts (7%).

Over the last 10 years, there has been a decrease in the number of new diagnoses of many STIs, but incidence of gonorrhoea and syphilis have increased.

The number of gonorrhoea diagnoses in 2023 was the highest since records began in 1918, and the number of syphilis diagnoses in 2024 was the highest reported since 1948. There is also concern that gonorrhoea has developed resistance to certain antibiotics, limiting the treatment options available.

HIV

Human immunodeficiency virus (HIV) weakens a person’s immune system and their ability to “fight everyday infections and disease”. HIV does this by destroying certain white blood cells (known as ‘CD4 cells’) that tackle infection.

HIV is treated using antiretroviral medicines (sometimes called antiretroviral therapy – ART). These stop the virus replicating in the body and allow the immune system to repair itself and prevent further damage. While there is currently no cure for HIV, ART is effective and can enable people with HIV to live a long and healthy life.

In January 2019, the government committed to achieving zero new transmissions of HIV in England by 2030 and put in place an action plan setting out how it would achieve this target. The plan was subsequently updated in late 2025 to cover the period up to 2030.

The chart below shows a decline in the number of new cases of HIV diagnosed in England between 2014 and 2021, followed by an increase from 2021 onwards.

This increase was largely explained by a rise in cases which were first diagnosed abroad. These infections were likely acquired abroad and therefore do not reflect a rise in transmission in England.
