But man sex chromosome have difficult to distinguish male and female, baby of female sex organ,
South Daily 3 Report on the 22nd in the moon (reporter Cao Si) Sex chromosome XX women, XY men, this has already been general knowledge. But recent, become mother's Ms Zhang (assumed name) for the second time But is getting " L Daughter " R Little Great Britain ' Assumed name) Chromosome inspection report at no, know whether what to do. Handle the third affiliated hospital hereditary disease of Guangzhou medical college in this case to determine Li Qing, expert of department, says: " What has been written was baby girl that born in the report, but the chromosome inspection result revealed small Great Britain was true man's body. " At present, the gender that Ms Zhang and husband are facing the child is chosen the difficult problem, very depressed.
Small Great Britain has man sex chromosome, but have female sex organs, this kind " L The fault " R Make people very puzzled. Li Qing says, the institute of wide medicine three met and examined several this kind of patients recently, she reminds mothers to reduce and contact the harmful substance in pregnancy period.
" L The fault " R Baby's gender difficulty is made
The elder son was born 5 years ago, but male genitals were not very obvious, Ms Zhang made chromosome inspection for children. The result is: The sex chromosome is XY, the genetic gender is men, but suffer from false two sexes syndrome of man, only grand sex hormone insensitive syndrome, all male external genitalia development is smaller than the ordinary person.
A few days ago, Ms Zhang came to institute of wide medicine three again. Little the intersection of daughter and little the intersection of Great Britain and half year old, she that have a lingering fear for insurance, determine, lead children make the chromosome, check. The result is not the good news . " L Daughter " R It is in fact man's body too, suffer from the same kind of disease with the elder brother, but more serious, can't find out the existence of the male external genitalia at all on the appearance.
Ms Zhang and husband want, cry, have tears, give gender of child it puts two into to be difficult choose. But she says, will not abandon these two children in any case, will not consider regenerating and breeding either.
" L The fault " R Do not know that there are early and many men
Why have " L The fault " R The man? Li is blue and green to explain, this is a kind of X chain recessiveness and hereditary disease which mothers carried. Carrying mother of the pathogenic gene if has given birth to the son, 50% probability demonstrate the pseudohermaphrodism. A sad one, such a patient raise as daughter more, seek medical advice until thinking oneself was infertile after growing up, the inspection result often brings the great blow to family. There was one 30 not long ago Married in a lot of years " L Lady " R Because amenorrhea has been had, sought medical advice infertily for many years, the chromosome is checked " L She " R It was men unexpectedly.
To two sons of Ms Zhang's, Li's blue and green suggestion, the elder son can choose to be a man, because he has a male other reproduction device, can pass the supplementary and androgenic therapeutic method, impel the development of sexual organ; But the young son is cumbersome, or choose male genitals to give a new lease of life to the operation, or choose the vagina to give a new lease of life to the operation, but under comparing, choose the latter to be relatively easy, and the result is better . " But in any case, can't be pregnant either after the patient, even if there is couple's life probably both sides are unsatisfied either, can only then consider realizing the other value of life. "
Li Qing says, false two sexes can not be managed to be found in sifting and looking into in period of pregnancy, and the environmental factor relation is not too big either. But probably the important period splitting up in foetus' organ, mother contacted the harmful substance to cause, she proposes mother should be very prudent definitely in pregnancy period.
