Perhaps you only want a girl baby or you already have that baby boy and just want to complete your happy family. For whatever reason you want to increase your odds for conceiving a baby girl there are some simple things you can do to improve them。

或許你們一心只想要女孩，當(dāng)然，也有可能你們已經(jīng)有了寶貝兒子，只不過(guò)希望能夠錦上添花，龍”鳳“呈祥。不管夫妻們是出于何種原因想要女兒，現(xiàn)實(shí)中也的確有一些簡(jiǎn)單的方法，可以提高懷上女孩的可能性。

How to Get Pregnant with a Girl with Timing of Conception

時(shí)間要準(zhǔn)：

Sperm contains two different types of chromosomes; the X chromosome and the Y chromosome. X chromosomes are slow swimmers but they are strong and resilient, they live longer than the Y carrying male counterparts。

精子里有兩種不同類型的染色體：X染色體和Y染色體。X染色體游動(dòng)得比較慢，但生命力和適應(yīng)環(huán)境的能力較強(qiáng)。相比于攜帶雄性基因的Y染色體，X染色體存活的時(shí)間更長(zhǎng)。

Because the sperm that carry the female (X chromosomes) are responsible for producing a baby girl you will want to introduce them at the point of time that the egg is present and the male (Y chromosome) sperm have been weakened or destroyed. The best time is about 3 or 4 days prior to ovulation. Once you have tracked and determined your date of ovulation plan on having intercourse as much as possible in the days prior. Do not have intercourse on the day of or the day following ovulation. By introducing the sperm prior to ovulation the male sperm will weaken and die off and all that are present to fertilize the egg are the female producing sperm. This increases your chance of conceiving a baby girl。

X精子(攜帶X染色體的精子)，是誕下女?huà)氲年P(guān)鍵。只有在卵子排出，且Y精子(攜帶Y染色體的精子)活性減弱或死亡的情況下，精確把握X精子與卵子結(jié)合的時(shí)間，才能確保懷上女孩。最好的交配時(shí)間，是在排卵前的大約3-4天，一旦排卵的準(zhǔn)確時(shí)間確定下來(lái)，夫妻之間應(yīng)盡可能地選在排卵前幾天發(fā)生性行為，絕對(duì)不要在排卵當(dāng)天或在第二天發(fā)生性行為。排卵期前性行為，能使Y精子在其與卵子結(jié)合前，活性漸失，并大量相繼死去，卵子得以與生命力更頑強(qiáng)的X精子相結(jié)合。這種方法可以增加懷上女孩的可能性。

How to Get Pregnant with a Girl using Positioning

姿勢(shì)要對(duì)：

The entrance of the vaginia is the least alkaline area of the vaginia. Y sperm are vulnerable to acidic environments and die off easily. Due to the fact that Y sperm does not survive well in acidic conditions if you use positions for intercourse that only allow for shallow penetration you can decrease the number of Y sperm that make it past the vaginia and into the race for the egg。

陰道口是女性陰道酸性最強(qiáng)的區(qū)域，而Y精子在酸性環(huán)境下十分脆弱、易死亡。因?yàn)閅精子在酸性條件下不易存活，如果夫妻之間在發(fā)生性行為的時(shí)候，能夠?qū)ψ鰫?ài)的體位加以控制，只進(jìn)行淺而緩的抽插，就能減少穿過(guò)陰道的Y精子數(shù)量，從而降低Y精子與卵子結(jié)合的機(jī)率。

How to Get Pregnant with a Girl by Maintaining an Acidic Environment for Sperm

環(huán)境要“酸”：

Male Y sperm survives well in alkaline environments but becomes weakened or destroyed in the presence of acidic environments. The female X sperm can survive in either climate. By maintaining an acidic environment in the vaginial cavity you can improve your chance of conceiving a baby girl. Orgasms increase the alkalinity of the vaginia and should be avoided if possible for optimal chances. Preventing or delaying female orgasm can maintain the acidic environment decreasing the number of Y sperm that travel to the egg and giving the slower more resilient X sperm a better chance of fertilizing the egg。

Y精子能夠在堿性環(huán)境下很好地生存，但在酸性環(huán)境下，精子的活性會(huì)受到削弱和破壞。而X精子在酸堿環(huán)境下，都能很好地生存。因此，維持陰道腔內(nèi)的酸度，可以增加懷上女?huà)氲目赡苄浴Ｐ愿叱睍r(shí)，陰道內(nèi)的酸度會(huì)下降，為了不錯(cuò)失“良機(jī)”，夫妻做愛(ài)時(shí)，應(yīng)盡量避免發(fā)生性高潮。防止女性發(fā)生性高潮，或延遲高潮到來(lái)的時(shí)間，可以維持陰道內(nèi)的酸度，減少經(jīng)由長(zhǎng)途跋涉、最終有能力到達(dá)卵子的Y精子數(shù)量，為X精子與卵子的最終結(jié)合，創(chuàng)造更好的機(jī)會(huì)。
