Question

State three things that could happen to a sperm after it has been deposited at point X

Answer 1

The complex process of sperm transport through the female reproductive tract begins at the time of ejaculation. During coitus, 1.5- to 5.0-ml of semen containing between 200 and 500 million sperm is deposited at the posterior vaginal fornix, leaving the external cervical os partially submerged in this pool of fluid.1 At this time, some sperm may be passively taken up by the cervix in a process described as “rapid transport;” otherwise, sperm undergo “delayed transport.” Both of these are discussed at length in this chapter.

The optimal pH for sperm viability is between 7.0 and 8.5,2,3,4,5 and a reduction in sperm motility is seen at a pH less than 6.0.6,7,8 Normal vaginal pH is only 3.5 to 4.0,9 and the acidic environment of the vagina is thus toxic to sperm. However, both seminal fluid and cervical mucus present within the posterior vagina are alkaline and act as buffers. Fox and coworkers have shown that vaginal pH rises to 7.0 within just seconds after ejaculation,10 and this decrease in acidity can be maintained for up to two hours after ejaculation.

Answer 2

Answer:

It will be described briefly below:

Explanation:

• Sperms are very active but sensitive substance

• It is the most motile substance and when goes in female reproductive tract it starts to search for its destination to bind, but there are abnormality which can affect the speed or life of sperm that are:

1. If the female reproductive tract are acidic in nature it will affect the sperm
2. The accumulation can leads to the slow down of some sperms
3. The affected sperm can not function properly which affect reproduction.
