OPINION
Appeal from the United States District Court for the District of Arizona.
Before WALLACE and TANG, Circuit Judges, and WHELAN, * District Judge.
The government appeals the dismissal of an indictment against Hicks and Davis alleging against Davis two counts and against Hicks one count of carnal knowledge of a female Indian under 16 years of age in violation of 18 U.S.C. § 1153 and § 2032. 1 In response to arguments that the statutes’ classification on the basis of gender denies equal protection under the law, the district judge dismissed the indictment. We affirm.
I
We first determine the proper standard of scrutiny to be applied in assessing the constitutionality of the statutes in question. The government does not dispute that the statutes classify on the basis of gender. Hicks and Davis argued before the district judge that only males can be perpetrators, and only females victims, of the crime of carnal knowledge. The statutes assign the roles of victim and criminal on the basis of gender. Had Hicks and Davis been female, they would not have been charged, 2 and the statute thus discriminates against males.
Because federal statutes are before us, we examine the constitutionality of the dissimilar treatment they impose pursuant to the Fifth Amendment. “[T]he Due Process Clause of the Fifth Amendment forbids the Federal Government from denying equal protection of the laws.”

In
Craig v. Boren,
II
At the hearing on the motion to dismiss, Hicks and Davis offered expert testimony and exhibits to demonstrate the unconstitutionality of section 2032. The court rejected these offers of proof. The government then argued that the statutes before us have two purposes: the prevention of unwanted pregnancy and the prevention of physical injury to young females. 3 It offered no evidence. The district judge stated that the statutes “[m]ay or may not have to do with pregnancy,” and, relying in part on Craig, dismissed the indictments. On appeal, the government’s central argument is that Hicks and Davis had the burden of going forward in this case and, therefore, that it first fell to them to show that the statutes did not satisfy the Craig standard. We disagree.
In
Berkelman v. San Francisco Unified School Dist.,
In
Craig,
the Court characterized the State’s statistical evidence as demonstrating an “unduly tenuous ‘fit’ ” between the gender classification and the asserted State objective,
In
Caban v. Mohammed, supra,
the Court declared unconstitutional a New York law which granted unmarried mothers, but not unmarried fathers, the right to withhold consent to adoption of their children. The Court rejected outright one of the State’s asserted reasons — that mothers are emotionally closer to their children than fathers.
Craig and Caban demonstrate that once an appropriate party invokes constitutional scrutiny of a statutory gender-classification, the government must shoulder the burdens of producing evidence and proving a constitutionally-sufficient justification. 4 They thus reaffirm our analysis in Berkel-man.
Hicks and Davis triggered constitutional scrutiny in their argument before the district judge by showing that the statutes facially discriminate against males. Each had standing to bring this challenge, because if the statute were unconstitutionally underinclusive, the district court would be required to dismiss the indictment. This provided a sufficient “personal stake in the outcome of the controversy” to afford standing.

It remains for us to determine whether the government met its burdens of producing evidence and proof in this case. We conclude that it did not.
The government has articulated two purposes behind the statutory scheme: prevention of teenage pregnancy and prevention of physical injuries to young females. 5 *220 But to demonstrate the relation between these purposes and the statutory penalties, it merely stated that “only women can get pregnant" and that there “seems to be evidence that women are far more likely to suffer physical damage” than are males of the same age. On appeal, the government asks us to take judicial notice of the fact that “intercourse correlates highly with pregnancy.” We do. Still, these naked assertions fail to carry even the government’s burden of producing evidence in this case, let alone to prove its contentions.
The government’s articulated objectives do suggest that Congress had some basis for defining criminal liability for heterosexual contact 6 in terms of the age of the female partner. But the government has produced not a shred of evidence demonstrating how either objective is “substantially” furthered by punishment only of the male. The absence of such evidence is particularly disturbing because the statute punishes males of any age, even in cases in which the male is younger than the female. 7 The government supplied no evidence that males necessarily always do or should bear greater responsibility for causing sexual contact. No evidence was produced explaining why punishment of males only is more likely to deter teenage pregnancies than punishment
of just females, or of both partners. Nor has the government proven why, in sexual contact between females under 16 and males of any age, the female, but not the male, is necessarily always “victimized,” or likely to suffer physical injury.
In the absence of any supporting evidence, we cannot accept the government’s assertions, which imply the broad generalization that males of all ages are larger, stronger, more sexually aggressive, and less likely to suffer physical injury from sexual contact than females. The government had the burden of showing why gender is a “sufficiently ‘accurate proxy,’ ”
Orr v. Orr, supra,
AFFIRMED.
Notes
Honorable Francis C. Whelan, United States District Judge, Central District of California, sitting by designation.
. 18 U.S.C. § 1153 states in part:
Any Indian who commits against the person or property of another Indian or other person any of the following offenses, namely, . carnal knowledge of any female, not his wife, who has not attained the age of sixteen years within the Indian country, shall be subject to the same laws and penalties as all other persons committing any of the above offenses, within the exclusive jurisdiction of the United States.
18 U.S.C. § 2032 states in part:.
Whoever, within the special maritime and territorial jurisdiction of the United States, carnally knows any female, not his wife, who has not attained the age of sixteen years, shall, for a first offense, be imprisoned not more than fifteen years, and for a subsequent offense, be imprisoned not more than thirty years.
The indictment charged Hicks and Davis under both statutes. Though we must necessarily decide the constitutionality of each, we decide only the constitutionality of that portion of § 1153 pertaining to the offense of carnal knowledge. See note 10 infra.
. The government asserts that carnal knowledge of a male by a female would be treated as an assault pursuant to 18 U.S.C. § 113 but does not contend that, absent an assault, females could be criminally liable for such conduct.
. While there is some question whether the government adequately raised the physical injury argument in the district court, the record clearly shows that the argument was mentioned. Therefore, the issue is properly before us.
. The government points out that a party challenging a
de facto
statutory classification, even one affecting a class protected by strict scrutiny, bears the burden of producing evidence that a statute, though facially-neutral, is applied in discriminatory manner.
See Hernandez v. Texas,
. None of the parties has found any legislative history that sheds light on the actual intent underlying the statutes before us. But we need not decide in this case Congress’ actual intent in passing these statutes, nor whether such
*220
history or other evidence of legislative intent might ultimately be required to satisfy the government’s burdens. As did the Court in
Craig,
we first assume the truth of the proclaimed objectives,
. Though we use “sexual contact” as the equivalent of conduct prohibited by the statutes in question, we do not thereby imply any legal definition of the term “carnal knowledge.”
. We are thus not asked merely to uphold a legislative judgment to give special protection to only one class of potential victims of exploitation (young females) by older persons, based on the unique harms flowing to that group. Instead, we are asked to uphold a legislative judgment that young females are victims in any case of sexual contact, no matter what the age of the male partner.
. The First Circuit overturned a similar New Hampshire statute in
Meioon v. Helgemoe,
Although the Fourth Circuit has twice rejected equal protection challenges involving the rape provisions of a West Virginia statute, the first decision,
Hall v. McKenzie,
State court decisions since
Craig
have sustained statutory rape provisions against claims of sex discrimination.
See, e. g., Michael M. v. Superior Court,
. Although the government concedes that it failed to suggest one further purpose before the district court, it now asks us to presume that a further goal of Congress in enacting these statutes was the protection of minors from sexual abuse. We need not decide, however, whether such a presumption would be appropriate, for we observe that the assertion of this purpose, assuming it to be valid, would still fail for lack of any evidence in the record of its relation to the gender-based classifications at issue here.
. We do not hold all of section 1153 unconstitutional. “ ‘Unless it is evident that the legislature would not have enacted those provisions which are within its power, independently of that which is not, the invalid part may be dropped if what is left is fully operative as a law.’ ”
