A) One of the factors that may influence the human reproductive process is the role of reproductive hormones. The reason being is that during the process of conception there are tremendous number of things that should not go wrong. For instant when the egg is being released from the ovary it enter the fallopian tube to await for fertilisation then the fertilised egg will travel down the fallopian tube and reaches the uterus to implant itself in the lining of the uterus. In this process for the pregnancy to be an achievable one there are hormones which need to be produced and these hormones are progesterone and oestrogen. The role of these hormones is to help the uterus to prepare itself for conception.
However this process can only be a result of a successful pregnancy if nothing went wrong which is that if the egg was not fertilised probably because it is not mature the level of progesterone will decreased and lead to menstruation. Reasons why there might be an unsuccessful pregnancy it is possibly because of the causes of infertility due to the deficiency of hormone production. This could be that the hormone that causes the pituitary gland to produce certain hormones that sends message to the ovaries to release oestrogen and progesterone was in a low amount of level. The production of progesterone and oestrogen is very important without it there will not be any form of conception because the egg would not being release from the ovary even if it does it will not be mature and be inactive for sperm and egg to fuse to fertilised. Other reasons could be that the amount of level of hormones of the man might be less which will due to low sperm count or sperm with poor quality that is slow in terms of movement and going the wrong direction.
Contraceptive pills play a role in the human reproductive process and the reason why is because the pill contain the two type of female hormones an oestrogen and progesterone. When this pill is taken it will prevent a woman from ovulate (producing egg) every month and it will thicken round the cervix which will cause the sperm to be unable to get through. Also the hormones in the pill causes the lining of the uterus to be thinner so that the egg cannot implant itself in the uterus since it
