delivered the opinion of the Court.

Appellant Otilio Serrano Ortiz was convicted by a jury of a violation of the modality provided in the second paragraph of '§ 260 of the Penal Code, 33 L.P.R.A. § 966,1 and sentenced to serve an indeterminate sentence of three to six years in the penitentiary. The trial court granted him the benefits of a suspended sentence.

1. Upon requesting the reversal of said sentence he adduces that the trial court erred in failing to give instructions to the jury on the necessity of weighing with caution the testimony of the aggrieved girl. He relies on well-established cases which construe § 288 of the Penal Code of California, West, Annotated California Codes, Penal Code, p. 183, phrased in a language similar to that of our § 260, supra.2

*727At the outset, the instruction to the effect that a charge of lewd and lascivious acts is easily made and, on the other hand, difficult to disprove, for which reason the testimony of the prosecutrix must be examined with caution, was refused by the courts in California, on the ground that this was not an instruction upon-a matter of law required to be presented by the court to the jury, People v. Harrison, 112 Pac. 733 (1910); People v. Anthony, 196 Pac. 47, 50 (1912); People v. Knight, 218 Pac. 79 (1923); People v. Agullana, 40 P.2d 848 (1935); cf. People v. Barnett, 278 Pac. 885 (1929). In 1938 the court begins to depart from the stated rule. In People v. Garrett, 81 P.2d 241, citing People v. Vaughn, 21 P.2d 438 (1933) it is maintained, in synthesis, that where there is corroborative evidence of the prosecutrix’s testimony it is not prejudicial error for the court to refuse to give a cautionary instruction, but that it is necessary where particular circumstances, like those herein,3 justify it for the purpose of attaining complete justice. Ultimately in People v. Lucas, 105 P.2d 102 (1940) they disapprove of the language used in People v. Anthony, supra which is classified as “unfortunate”, and from the opinion rendered in People v. Adams, 93 P.2d 146 (1939) it is cited: “There is no class of prosecution attended with so much danger, or which afford so ample an opportunity for the free play of malice and private vengeance.” It does not suffice, however, to inform the jury that a minor’s testimony in the sex cases should be examined with caution, for it tends to convey the impression that for undisclosed rea*728sons the trial judge distrusts the testimony of the particular witness; it is necessary that the jury be specifically informed that these charges are easily made and place the defendant in a peculiarly vulnerable position, usually with no defense except his own denial of the asserted misconduct, People v. Putnam, 129 P.2d 367 (1924).4 At page 370 it was said: “The rule permitting a conviction on the uncorroborated testimony of the prosecuting witness is necessary to protect the public but it needs a counterweight to protect the accused .... the very secrecy that precludes corroboration also precludes effective denial. The ordinary reaction to an accusation of a sex offense usually committed in secret is that the offense has been committed, and a necessary safeguard against injustice is a warning to view such accusations cautiously.” Since then the rule on the necessity to give the instruction has been uniformly followed. People v. Elliot, 322 P.2d 1029 (1958); People v. Lyons, 303 P.2d 329 (1956); People v. Norton, 297 P.2d 439 (1956); People v. Buchel, 296 P.2d 113 (1956); People v. Trolinder, 264 P.2d 601 (1954); People v. Ernst, 263 P.2d 114 (1953); People v. Clark, 255 P.2d 79 (1953); People v. McCracken, 246 P.2d 913 (1952); People v. Norred, 243 P.2d 126 (1952); People v. Todd, 205 P.2d 453 (1949); People v. Westek, 190 P.2d 9 (1948); People v. Ahsbahs, 175 P.2d 33 (1946). See, 30 Cal. Jur.2d, Lewdness, Indecency and Obscenity, § 44; Note, Lewd and Lascivious Conduct with a Child: Need for Corroboration, 41 Calif. L. Rev. 744 (1953) and 48 Calif. L. Rev. 648, 673-676 (1960).

The grounds stated to justify the rule we have discussed having been considered the reasonings adduced to *729request the instruction that the prosecutrix’s testimony he weighed with caution are persuasive.5 Now then, the failure to give said instruction does not constitute reversible error in all cases. It depends on the concurring circumstances, People v. Taylor, 199 P.2d 751 (1948). Thus, where the prosecutrix’s testimony has been corroborated by direct or circumstantial evidence, People v. Taylor, supra; People v. Roberts, 123 P.2d 628 (1942), or where, in the opinion of the appellate court, the verdict would not have been different because the evidence is convincing, is not sharply conflicting, and is not inherently improbable, People v. Rankins, 153 P.2d 399 (1944); People v. Trumbo, 141 P.2d 225 (1943); People v. Putnam, supra; People v. Lucas, supra, failure to give the instruction does not constitute prejudicial error.

An examination of the record of this case suffices to show that the minor’s testimony was not only corroborated as to certain points by the evidence for the prosecution, but also by the testimony of appellant himself. Furthermore, we do not believe the result would have been different had the jury been instructed as indicated.

2. Appellant argues that the jury was not instructed as to the offense of aggravated assault and battery. The evidence does not justify it. People v. Arce Valentín, supra.

The errors assigned not having been committed, the judgment rendered by the Superior Court, Bayamón Part, on July 30, 1964, will be affirmed.
