Appellant was tried before a jury on two counts of aggravated sodomy of his young daughter. The jury returned a verdict finding appellant guilty of both counts. Appellant’s motion for new trial was denied and he appeals from the judgments of conviction and sentences entered on the jury’s verdicts.
*1581. Appellant enumerates the general grounds. The testimony of the victim, standing alone, authorized the finding that appellant had committed the crimes with which he was charged. There is no longer any requirement that the victim’s testimony be corroborated. See Motes v. State, 161 Ga. App. 173 (3) (288 SE2d 256) (1982). Appellant’s contention that the expert medical evidence contradicted the victim’s testimony is refuted by the transcript. To the contrary, the medical testimony established that the victim’s physical condition was not necessarily inconsistent with the commission of the acts that the victim had attributed to appellant.
“ ‘It is the function of the jury, not the appellate court, to determine the credibility of witnesses and weigh any conflict in the evidence. The appellate court views the evidence in the light most favorable to the jury’s verdict after it has been rendered. [Cit.]’ ” Bowers v. State, 164 Ga. App. 462 (1) (297 SE2d 359) (1982). After a review of the entire record, we find that a rational trier of fact could reasonably have found from the evidence adduced at trial proof of appellant’s guilt beyond a reasonable doubt. Jackson v. Virginia, 443 U. S. 307 (99 SC 2781, 61 LE2d 560) (1979).
2. Appellant complains that the court erroneously overruled an objection to hearsay testimony when the victim’s mother was asked about her conversation with the victim. He asserts also that the error was reversible.
The trial scenario is as follows.
The victim testified on direct examination that she told her mother about the sexual relations with her father, after they moved out of the family home, on her grandmother’s porch, and that the next day they went to the sheriff’s office and then the hospital.
Defendant’s attorney then cross-examined the victim and asked several questions about whether other girls told her about anything that happened to them “before you told your mama.” He also cross-examined the victim about the conversation with her mother at great length:
“Q. Then, you say that you told your mother about it at your grandmother’s?
A. Yeah.
Q. Why did you tell her about it, [name]?
A. I was scared.
Q. Okay. Now who all was there on that front porch at your mamaw’s when you told this to your mother?
A. Me and mama.
Q. Anybody else?
A. Huh-uh. . . .
Q. Well, you’ve talked about it with your grandmother, haven’t you?
*159A. I guess I did. I don’t know.
Q. Okay. Isn’t it true, [name], that your grandmother started asking you about this before you told your mother?
A. (Witness shakes head from side to side.)
Q. You’re certain of that?
A. Yeah.”
He kept cross-examining her about it.
On redirect examination, the victim acknowledged that she talked to her mother about what had happened to her, and that her mother did not make the story up for her and that her friend Vickie helped the victim decide to tell her mother.
The examining doctor testified that the victim was brought in to Tri-County Hospital by her mother and an officer from the Dade County Sheriff’s Department and that he gave a general physical examination. He further testified that the vagina was unusually enlarged, indicating that something had been put into it over repeated times, and that although the anus appeared normal, that would not necessarily mean there had not been a violation of it lay an adult male sex organ.
The mother testified that she took the victim to the sheriff’s office because of a conversation she had had with the victim the day before. Defendant objected on grounds of hearsay when the mother was asked the question: “I don’t want you to go into any detail, but what basically was the — .” The court allowed the mother to testify what the victim told her, which is what prompted the mother to take the victim to the sheriff’s office, after the court instructed the jury that it was for the limited purpose of explaining the mother’s conduct in taking the victim there. The court further explained that it was not to be considered for the truthfulness of the information, that is whether the content of what the victim said to the mother was true or not.
“Q. Could you tell us, then, what was it that you were told that led you to take [victim] to the Sheriff’s Office?
A. She told me that Clines was taking her to the bedroom of a night when I was at work.”
It is that answer that the appellant contends was reversible error to admit, i.e., inadmissible hearsay which was unlawfully prejudicial to defendant.
However, even if the objection should have been sustained, admission of the mother’s answer, considering its content and its place in the context of all the other evidence, including evidence elicited by defendant, was not reversible error. Since it is a non-constitutional error, the test that applies is whether it is highly probable that the error did contribute to the judgment. Johnson v. State, 238 Ga. 59, 61 (230 SE2d 869) (1976); Teague v. State, 252 Ga. 534, 537 (314 SE2d *160910) (1984). It did not.
Even if the error were constitutional, it would not require reversal. In such cases the standard is harmlessness beyond a reasonable doubt. Harrington v. California, 395 U. S. 250 (89 SC 1726, 23 LE2d 284) (1969); Schneble v. Florida, 405 U. S. 427 (92 SC 1056, 31 LE2d 340) (1972). Considering everything, the jury’s hearing the mother’s statement was harmless beyond a reasonable doubt.
a. The defendant made an issue of whether or not the victim told her mother, by cross-examining her all about the communication, prior to her mother’s testimony. He opened the door to the later question to the mother as to whether the victim did tell her about it.
b. A primary reason for the exclusion of hearsay testimony is that its truthfulness cannot be tested under oath before the trier of fact through the examination of the sayer. Its credibility is thus not able to be established to the degree necessary to render it worthy of consideration in the investigation for the truth. Glisson v. State, 57 Ga. App. 169, 170 (194 SE 877) (1938); Peacon v. Peacon, 197 Ga. 748 (30 SE2d 640) (1944). Here, although made out of court, the speaker as well as the hearer were both subject to thorough and sifting cross-examination under oath, before the jury, about what the speaker said.
c. The object of all legal investigation is the discovery of the truth. If the credibility of a witness is at issue, as here the victim’s was, whether she told her mother of the incident, as she testified she did, was an issue of fact. It would have weakened her credibility if the mother testified that the victim told her something different than what the victim testified she told her mother, or different than what the victim testified had actually occurred.
d. While it may be true that the mother’s conduct was not in issue, the victim’s conduct and truthfulness certainly were. Had the 12-year-old fifth grader not told her mother, that fact would have been relevant to her veracity. The fact that she did tell her mother lends credibility.
e. The victim’s testimony was corroborated to a degree by the physician’s examination.
f. It is obvious from the evidence, absent the simple objected-to, rather inconclusive single-sentence answer of the mother, that the victim told her about some sexual conduct with defendant. The mother did not describe the conversation in great detail and was not even explicit as to any sexual activity. As a matter of fact, she only testified that the victim told her that the defendant was taking her to the bedroom while the mother was at work. Her answer was less damaging to defendant than would have been the reasonable inferences that could have been drawn from the circumstances. But there was no objection to the evidence that the mother took the victim to the sheriff the next day and then to the hospital for examination, and that the *161doctor examined her and found evidence of penetration of the vagina, and that she accused the father of violating her. This not only allows a reasonable inference by the jury of the fact that the victim told her mother about it but almost demands such a finding in the exercise of common sense. The evidence is so overwhelming that the child told her mother about it that for the mother to say, “She told me that Clines was taking her to the bedroom of a night when I was at work,” is cumulative and inconsequential when viewed in the context of all of the other evidence which nearly swallowed it up. The mother made this statement after being allowed to testify that the child did have a conversation with her. Had the objection been sustained, the jury could have reasonably inferred from all the circumstances and subsequent activity that the child told her mother much more than that, and the reasonable inferences could have been much more damaging to defendant than the short statement.
Decided December 5, 1984 Rehearing denied December 20, 1984 James A. Meaney III, for appellant. David L. Lomenick, Jr., District Attorney, Herbert E. Franklin, Jr., Assistant District Attorney, for appellee.3. We have examined the recharge, which was prompted by a jury question, and find no error. It correctly explained the instruction given in the charge, with respect to the elements of the crimes.
Judgment affirmed.
