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。

或许你们一心只想要女孩，当然，也有可能你们已经有了宝贝儿子，只不过希望能够锦上添花，龙”凤“呈祥。不管夫妻们是出于何种原因想要女儿，现实中也的确有一些简单的方法，可以提高怀上女孩的可能性。

How to Get Pregnant with a Girl with Timing of Conception

时间要准：

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。

精子里有两种不同类型的染色体：X染色体和Y染色体。X染色体游动得比较慢，但生命力和适应环境的能力较强。相比于携带雄性基因的Y染色体，X染色体存活的时间更长。

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(携带X染色体的精子)，是诞下女婴的关键。只有在卵子排出，且Y精子(携带Y染色体的精子)活性减弱或死亡的情况下，精确把握X精子与卵子结合的时间，才能确保怀上女孩。最好的交配时间，是在排卵前的大约3-4天，一旦排卵的准确时间确定下来，夫妻之间应尽可能地选在排卵前几天发生性行为，绝对不要在排卵当天或在第二天发生性行为。排卵期前性行为，能使Y精子在其与卵子结合前，活性渐失，并大量相继死去，卵子得以与生命力更顽强的X精子相结合。这种方法可以增加怀上女孩的可能性。

How to Get Pregnant with a Girl using Positioning

姿势要对：

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。

阴道口是女性阴道酸性最强的区域，而Y精子在酸性环境下十分脆弱、易死亡。因为Y精子在酸性条件下不易存活，如果夫妻之间在发生性行为的时候，能够对做爱的体位加以控制，只进行浅而缓的抽插，就能减少穿过阴道的Y精子数量，从而降低Y精子与卵子结合的机率。

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

环境要“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精子能够在碱性环境下很好地生存，但在酸性环境下，精子的活性会受到削弱和破坏。而X精子在酸碱环境下，都能很好地生存。因此，维持阴道腔内的酸度，可以增加怀上女婴的可能性。性高潮时，阴道内的酸度会下降，为了不错失“良机”，夫妻做爱时，应尽量避免发生性高潮。防止女性发生性高潮，或延迟高潮到来的时间，可以维持阴道内的酸度，减少经由长途跋涉、最终有能力到达卵子的Y精子数量，为X精子与卵子的最终结合，创造更好的机会。
