Sexual health in your thirties

A decade in which several things arrive at once: routine screening, contraception decisions that no longer match the choice made at twenty, fertility questions with a timescale attached, and symptoms that were previously waved away.

Cervical screening

Screening programmes differ between countries in starting age, interval and technique. In most, screening begins in the early to mid twenties, continues into the sixties, and now tests first for human papillomavirus, with cell changes examined only where the virus is found. That change makes the test more sensitive and allows longer intervals for people who test negative.

Two things are worth knowing. First, screening looks for changes before they become cancer, which is why attending when there are no symptoms is the entire point. Second, a normal screening result is not a test for sexually transmitted infections, and it says nothing about chlamydia, gonorrhoea, HIV or syphilis.

Attendance falls in this decade, and the reasons given are consistent: time, embarrassment, previous discomfort and, for some, pain that made the last appointment intolerable. All of those can be worked with. A smaller speculum, a longer appointment, lying in a different position, self insertion of the speculum, or in some programmes a self collected sample are all reasonable to ask about. Anyone who finds examinations painful should say so when booking rather than at the moment it starts. See vaginismus.

Symptoms between screenings still need review. Bleeding after sex, bleeding between periods and persistent unusual discharge should be assessed regardless of when the last test was.

Contraception

The decision changes as circumstances do. Someone who wanted a method that could be stopped instantly at twenty two may want one that requires no thought at thirty six. Someone with heavy periods may benefit from a method that treats them as well. Someone approaching the end of their family may be considering a permanent option.

Practical points specific to this decade: combined hormonal methods become less suitable with certain risk factors that appear with age, so a review is worthwhile rather than a repeat prescription indefinitely. Long acting methods have the highest real world effectiveness. Condoms remain the only method that reduces infection transmission. See the contraception overview.

Pain that has been dismissed

The thirties are commonly when period pain finally gets investigated, often years after it started. The features that distinguish problematic pain from ordinary period pain are worth stating plainly: pain that stops normal activity, that does not respond to standard pain relief, that begins before bleeding, that comes with deep pain during sex, pain opening the bowels during a period, or difficulty conceiving.

That combination is the classic picture of endometriosis, and describing the impact rather than the intensity is what usually moves an appointment forward. Heavy bleeding is a separate issue that also deserves treatment, not least because it causes iron deficiency.

Fertility

Fertility declines gradually from the early thirties and more noticeably from the late thirties. The usual advice is to seek assessment after a year of trying without success, or after six months for women over thirty five, and sooner where there are known factors such as irregular cycles, endometriosis, previous pelvic infection or previous pelvic surgery.

Assessment covers both partners. Anyone considering delaying pregnancy, or considering egg freezing, is entitled to a factual conversation about what the options involve and what the realistic expectations are.

After birth

Many people in this decade are recovering from one or more births. The symptoms most often normalised are leaking, heaviness, pain with sex and difficulty controlling wind. All four are common and all four are treatable, and treating them at thirty five gives a much better result than treating them at fifty five. See the pelvic floor after childbirth and the first year after birth.

Infection testing

Testing when partners change remains relevant at every age. Most sexually transmitted infections cause no symptoms, chlamydia in particular, and untreated infection is a preventable cause of tubal damage. Testing is largely self collected and available without a general practitioner in most countries. See testing for sexually transmitted infections.

Breast awareness

Knowing what is normal for your own breasts matters more than any particular technique. Changes worth reporting include a new lump or thickening, a change in shape or size, skin dimpling or puckering, a rash or change around the nipple, nipple discharge that is new, or persistent pain in one area. Most changes turn out to be benign, and the point of reporting them is that the ones that are not are far more treatable when found early. Routine screening programmes generally begin later than this decade, so symptoms in the thirties are assessed on their own merits.

Early menopause

Uncommon but not rare. Menopausal symptoms before forty five, and particularly before forty, need assessment rather than being attributed to stress. See perimenopause.
