Who Should Be Eligible to Play Women’s Cricket?

Marizanne Kapp, Anaya Bangar, male puberty, testosterone — and the difficult line between inclusion and fairness.

Some conversations in sport have become so politically charged that it can feel almost impossible to discuss them without immediately being placed on one side or the other.

Transgender participation in women’s sport is one of them.

Support inclusion and you may be accused of ignoring women’s sporting rights.

Question whether someone who experienced male puberty should compete in a protected female category and you may be accused of prejudice.

Yet women’s cricket needs to be capable of having this conversation without reducing transgender people to an argument — and without pretending that biological sex, puberty and testosterone are irrelevant to sporting performance.

South African all-rounder Marizanne Kapp recently entered that debate very publicly.

After transgender cricketer Anaya Bangar was cleared to play women’s community and Premier cricket in Australia, with a possible pathway towards elite domestic cricket, Kapp posted:

“Absolutely ridiculous, this should NOT be allowed!”

Bangar responded by urging critics to educate themselves about transgender athletes and the process she had undergone.

Perhaps education is exactly where this conversation should begin.

Because the question is considerably more complicated than either “trans women are women, therefore they should play” or “they were born male, therefore there is nothing more to discuss.”

The real sporting questions concern puberty, testosterone exposure, physiology and the purpose of creating a separate women’s category in the first place.

Why Do We Have a Women’s Category?

Not because every man is stronger or faster than every woman.

There is enormous overlap between individuals. There are women stronger than many men, tall women, short men, exceptionally athletic women and relatively unathletic men.

Sport separates the sexes because, at population level, male puberty produces substantial average differences in size, strength and power that affect sporting performance.

That distinction — from puberty onwards — is important.

Before puberty, the physical performance differences between boys and girls are considerably smaller. Testosterone-driven puberty then produces a range of changes that become highly relevant in competitive sport.

The International Cricket Council’s eligibility regulations recognise this. The ICC notes the significant average advantages in size, strength and power that develop following male puberty and uses those differences as part of the rationale for maintaining a protected women’s category.

What Does Male Puberty Actually Do?

During typical male puberty, increased testosterone contributes to greater skeletal muscle mass, strength, haemoglobin levels and changes in body dimensions and composition.

None of this determines whether someone will become a good cricketer.

Skill matters enormously.

Technique matters. Coordination matters. Training matters. Decision-making matters. Temperament matters.

But physical characteristics matter too.

A fast bowler converts strength, speed, leverage and coordination into ball velocity.

A batter generates bat speed and power.

Fielders sprint, throw, dive and repeatedly produce explosive movements.

So when cricket regulators discuss male puberty, they are not making a judgement about somebody’s identity.

They are asking whether developmental exposure to higher testosterone produces physical characteristics that matter inside a protected female sporting category.

But Transition Changes the Body Too

This is equally important to understand.

A transgender woman undergoing feminising hormone treatment does not simply retain completely unchanged male physiology.

Reducing testosterone produces real physical changes.

Research has shown reductions in haemoglobin, lean body mass, muscle size and strength following feminising hormone treatment.

So saying that hormone treatment makes absolutely no difference is not scientifically accurate.

The more difficult question is:

That is where the science becomes considerably less certain.

Some studies have found that certain performance differences diminish substantially over time.

Other research has found that differences in muscle mass or strength may remain after extended periods of hormone treatment.

More recent reviews have also highlighted the limited quality and relatively small amount of elite-athlete data available.

The responsible conclusion therefore is not:

“Hormone treatment changes nothing.”

Nor is it:

“Every transgender woman will always possess an overwhelming sporting advantage.”

The evidence is more complicated than either position.

What we know much more confidently is that male puberty creates significant average physiological differences, hormone treatment changes several of those characteristics, and there remains scientific uncertainty around exactly how much relevant advantage persists in different sports.

The Anaya Bangar Case

Anaya Bangar previously played male age-group cricket in India before transitioning.

She has subsequently been cleared to participate in women’s cricket in Australia under Cricket Australia’s domestic framework.

This has sometimes been described online as Bangar simply being allowed into the Women’s Big Bash League.

That is not accurate.

Being eligible to follow an elite cricket pathway and actually being selected or contracted by a WBBL team are very different things.

Selection would still depend on performance, opportunity and a team choosing to contract her.

But Bangar’s case has exposed something much more interesting:

That is because international and domestic cricket currently draw the line differently.

Where Has the ICC Drawn the Line?

The ICC has taken a relatively clear approach to international women’s cricket.

Under its current eligibility regulations, a transgender woman may be eligible for international women’s cricket only if she did not progress through male puberty beyond Tanner Stage 2 or beyond the age of 12, whichever occurred first, together with additional hormonal requirements.

In practical terms, a transgender woman who experienced typical male puberty is not eligible for international women’s cricket.

This remains the case regardless of later surgery or hormone suppression.

The important point is that the ICC rule is not simply:

“Transgender women cannot play.”

It asks a much more specific physiological question:

The ICC has identified male puberty as the relevant boundary for international women’s cricket.

What About Someone Who Never Experienced Male Puberty?

This distinction is frequently lost on social media.

Consider two transgender women.

One transitions as an adult after completing male puberty.

The other receives medical treatment early enough that she does not progress through typical testosterone-driven male puberty.

Those athletes have not experienced the same physiological development.

That is precisely why the ICC regulations include puberty history.

A transgender girl who does not undergo male puberty has not acquired the same suite of male-puberty-related characteristics as someone who transitions after adolescence.

Whatever position one ultimately takes on eligibility, treating those two situations as biologically identical does not help the discussion.

Now Consider Transition in the Opposite Direction

There is another part of this conversation that receives far less attention.

What happens when a player who was born female and has played women’s cricket transitions to male?

A transgender man may begin taking testosterone as part of gender-affirming treatment.

And suddenly testosterone becomes impossible to ignore.

Testosterone is not merely cosmetic.

Over time it can increase muscle development, alter body composition, increase haemoglobin and produce a range of masculinising physical characteristics.

In competitive sport, externally administered testosterone is also classified as an anabolic androgenic steroid.

Under the World Anti-Doping Agency rules, testosterone is a prohibited substance unless an athlete meets the requirements for a Therapeutic Use Exemption where applicable.

WADA Prohibited List

This is relevant to the broader conversation because it demonstrates something fairly straightforward:

When a female-born athlete takes testosterone, sporting authorities recognise that it can alter performance-relevant physiology.

That naturally raises a difficult question when we look in the opposite direction:

If testosterone exposure is sufficiently important to consider when a female-born athlete begins taking it, how should sport regard years of testosterone exposure through male puberty before a transgender woman begins hormone suppression?

The situations are not identical.

A transgender man beginning testosterone treatment as an adult is not going through exactly the same developmental process as an adolescent boy experiencing puberty.

Likewise, reducing testosterone in a transgender woman can reverse several physiological characteristics.

But the comparison illustrates why the discussion cannot simply dismiss testosterone as irrelevant.

Does Testosterone Change Someone’s Biological Sex?

This is another area where language matters.

It would be overly simplistic to say that taking testosterone completely changes someone’s biological sex.

Human biological sex involves several characteristics, including chromosomes, reproductive anatomy, gonads, hormone exposure and secondary sex characteristics.

Medical transition can significantly change some of those characteristics while not changing others.

From a sporting perspective, however, the philosophical question of exactly how sex should be defined is not necessarily the most useful question.

The more relevant question is:

That is ultimately what sporting governing bodies are trying to regulate.

A Blood Test Does Not Tell the Whole Story

Current testosterone levels are important, but they do not necessarily tell us everything about an athlete’s physical development.

A transgender woman who has experienced male puberty may later suppress testosterone to very low levels.

Her haemoglobin may decrease.

Muscle mass may decrease.

Strength may decrease.

But some characteristics associated with development during puberty — including aspects of skeletal size, height and limb proportions — are not simply reversed by reducing testosterone later in life.

This is one reason sporting bodies can examine similar evidence and adopt very different rules.

One policy might place greater emphasis on an athlete’s current hormone level.

Another might place greater emphasis on whether male puberty occurred at all.

For international women’s cricket, the ICC has chosen the latter approach.

Why Does Australia Have Different Rules?

Because ICC eligibility regulations govern international cricket.

Domestic cricket remains largely the responsibility of individual national governing bodies.

Cricket Australia therefore operates its own transgender and gender-diverse participation policies.

At community level, Australian cricket places considerable emphasis on inclusion and allows transgender players to participate according to their affirmed gender under its community framework.

Elite cricket has additional eligibility requirements and medical assessment.

This creates the unusual possibility that a player could potentially be eligible for an elite domestic competition but remain ineligible to play international women’s cricket.

Cricket Australia: transgender and gender-diverse participation

Should Social Cricket and Elite Cricket Have the Same Rules?

This is another important question.

Not every cricket match is a World Cup final.

A social cricket club trying to encourage people to be active, make friends and participate in the game has very different objectives from international cricket.

At recreational level, inclusion and participation may reasonably carry much greater weight.

But the further one moves towards elite competition, the more difficult the balance becomes.

Professional contracts are limited.

National places are limited.

Provincial selection places are limited.

Records matter.

Championships matter.

Selection can determine whether someone receives funding, sponsorship or a career opportunity.

And the entire reason a protected women’s sporting category exists is to create competitive opportunities that would otherwise be drastically reduced if sport operated as one unrestricted category.

It therefore may not be unreasonable for social, club, provincial, professional and international cricket to have different participation thresholds.

But whatever those rules are, they should be clear and understood before players take the field.

And Then There Is Masters Cricket

This discussion becomes particularly interesting in Masters sport.

Masters cricket should absolutely be about enjoyment, friendship, travel, competition and keeping people involved in the game for longer.

But once an event becomes a serious competition — particularly one involving national teams or using terminology such as “World Cup” — eligibility questions inevitably arise.

Who defines the women’s category?

Which governing body’s regulations apply?

Is the tournament sanctioned?

Does it follow ICC eligibility rules?

If not, what rules does it use?

Are those rules published before players register?

And do all participating teams understand the eligibility framework they are competing under?

Those are not anti-trans questions.

They are sporting governance questions.

A competition presenting itself as a women’s international tournament should have a transparent definition of eligibility.

Protecting Women’s Sport Does Not Require Hostility Towards Transgender People

This is perhaps where the conversation most often breaks down.

A transgender cricketer is not an abstract political problem.

She is a person.

She may have played cricket from childhood.

She may have teammates, coaches and friends within the sport.

She may have gone through an extremely difficult process of understanding her identity and transitioning.

And she may simply want to continue playing the game she loves.

That deserves empathy.

But empathy cannot be the only principle governing competitive sport.

Female athletes also have legitimate interests.

They have spent years training for limited places.

Women’s competitions exist specifically because sex-linked physiological differences affect sporting performance.

Protecting that category is not inherently an attack on transgender people.

Likewise, treating transgender athletes with dignity does not require pretending that biological development does not matter.

Both ideas can exist at the same time.

Perhaps Education Is Exactly What We Need

Marizanne Kapp’s reaction was blunt.

Anaya Bangar’s response was essentially that people should educate themselves before commenting.

There is value in doing exactly that.

Understand what male puberty does.

Understand what lowering testosterone does.

Understand what hormone treatment may not completely reverse.

Understand that a transgender woman who never experienced male puberty presents a different physiological question from someone who transitioned after completing it.

Understand why testosterone treatment becomes relevant when a female-born athlete transitions in the opposite direction.

Understand that the available science still contains uncertainty.

And then ask what level of uncertainty a protected sporting category should reasonably accept.

People can disagree about where that line should sit.

What should not be controversial is that the conversation itself is legitimate.

The Conversation Needs to Continue

There should be space in women’s cricket to discuss fairness without cruelty.

There should also be space to discuss inclusion without dismissing female athletes who have concerns.

The subject is complicated.

The science is still developing.

Different cricketing bodies have drawn the line in different places.

And reasonable people will not always reach the same conclusion.

But silence is not a solution.

Neither is shouting people down.

Women’s cricket should be mature enough to have difficult conversations, listen to the science, listen to the athletes affected on all sides, and insist that governing bodies establish clear, transparent and defensible rules.

Because fairness and compassion should not have to be enemies.
