Cardinal Wordss: Mother ‘s age, Last catamenial Period, Month of Conception, sex anticipation, Sex planning, Chinese Method. —
The ultimate purpose of every married adult female remains to be a female parent. Marital life starts with guess and planning of kids, their Numberss and sex. Fertility, which refers to holding construct or existent kid bearing, becomes the foremost desire. Gender of the pick is a natural desire of a adult female. However on first gestation this desire remains hibernating in the supplications.
During initial phases of gestation suspense remain in cognizing the sex of an unborn babe. Assorted scientific methods are available for the anticipation of the sex of the foetus. These include Chorionic villus sampling ( CVS ) , amniocentesis and ultrasound. Other methods used to foretell the sex of foetus after construct are Old married womans narratives, foetal bosom rate trial, draino trial and Chinese lunar calendar ( CLC ) method etc. The most popular method is extremist sound which is best done between 18 and 26 hebdomads of gestation but its truth depends upon several factors: babe ‘s cooperation, gestational age, technician ‘s ability, etc ( 1 ) .
Once the twosome have the babe of either sex and wants to hold the babe of their ain pick, they go for gender choice or planning of methods which provide counsel for following steps before construct. There is a broad prevailing tendency among pregnant adult females of developing states of holding a penchant for male child babes. In states like China, India, and Korea socio-cultural environments do be which contribute to boy kid prejudice in attitude and action ( 2 ) . A societal study on gender penchants prepossession sex choice among pregnant adult females in Karachi, Pakistan revealed that 27.6 % Pakistani adult females do demo a statistically important penchant for male childs over misss ( 3 ) , In Egypt a survey found 1.4 overall boy penchant index ( 4 ) Among the United States general population harmonizing to a cross-sectional web-based study, 39 % of respondents liked their first kid to be a boy, and 19 %
liked their first kid to be a girl ( 5 ) .However on big graduated table, prepossession sex choice for non medical grounds raises of import lesson, legal, and societal issues and it can take to a socially riotous instability of the sexes.
The methods which provide the option of planning of sex of the babe before construct include the Shettles method and Chinese lunar calendar method. Shettles method named for Dr. Landrum Shettles, based on timing of sexual intercourse in relation to ovulation, sexual place and adult females orgasm ( 6 ) . The Chinese lunar calendar chart ( Table – 1 ) has the advantage of utilizing it for planning of sex of the babe before construct and foretelling the sex even after construct. Harmonizing to fable, the Chinese birth gender chart is based on statistics taken from adult females inside the out metropolis during the China dynasty. This chart was discovered by a Chinese scientist around 700 old ages ago buried in a royal grave. Original transcript of the chart is now placed in the institute of scientific discipline of Beijing China. Accuracy of this chart is claiming to be 99 % and is based on female parent ‘s age and month of construct which are converted into their lunar equivalents ( 7 ) . Globally really few surveies have been conducted on this method but in Pakistan no such record were found.
The purpose of this survey was to prove the truth and prognostic value of Chinese calendar method in a sample of pregnant adult females admitted for hospital bringing at PNS Shifa Hospital Karachi.
SUBJECT AND METHODS
This was a longitudinal descriptive survey in which truth of the Chinese method of foretelling sex of unborn babe was noted in the conceived adult females. Pregnant adult females holding full term gestation labeled bringing instances and admitted in officer ‘s household ward of Pakistan Navy Ship Shifa infirmary from 31 March 2010 to 11 June 2010 were included in the survey. Civilian non entitled ( CNE ) class of the adult females was included as compared to services forces households sing their better socio economic conditions, instruction and better place of remembering the day of the month of last catamenial period ( LMP ) .

The average gestational age was 36 hebdomads. Out of 100 delivered babes 42 were misss and 58 were male childs. Among 42 miss babes 19 were right predicted, hence the method holding a sensitiveness of 45.23 % and specificity of 53.44 % . Out of 58 male childs babes 31 right predicted with a sensitiveness of 53.44 % and specificity of 45.23 % ( Figure – 2 ) . .The positive predicted values calculated for foretelling male childs was 57.40 % and for misss 41.30 severally.
Family / Community physicians like accoucheurs while covering with a pregnant lady normally encountered the inquiry about anticipation of sex of foetus.
