Health Issues Related to the Human Reproductive System

Infertility in male and female:

Causes of interfility	Description
Less sperm count	Probability of fertilisation to occur is low
Abnormal sructure of sperm	Sperms do not function and fertilisation does not occur
Blockage of sperm duct	No sperm found in semen
Inactive sperm	Sperm unable to move to Fallopian tube for fertilisation
Infection in testis	No sperm formed or abnormal sperm formed
Impotence	Sexual reproduction does not occur

Female:

Causes of infertility	Description
No ovum formed	Fertilisation does not occur
No ovulation	No ovum is released and fertilisation does not occur
Blockage of Fallopian tube	Sperm could not fertilise with ovum
Uterus problems (abnormal structures,tumuor)	Implantation difficult or does not occur
Irregular menstrual cycle	Production of ovum and ovulation is affected

Overcoming infertility in male:

Sperm bank

Donor's sperms are collected and stored frozen in liquid nitrogen at a temperature of -196 degree celcius
The sperms chosen by the couple will be injected into the woman's Fallopian tube during ovulation

2. Artificial insemination (AI)

Due to the small amount of sperm, this technique will accumulate sperms over a certain period of time to achieve a large quantity
Sperms are injected into the Fallopian tube during ovulation

Infertility treatment:

In vitro fertilisation (IVF)

A mature ovum is removed form the ovary and is fertilised by the sperm in a culture plate in the laboratory
Fertilisations occurs after 5-6 hours
The fertilised ovum is re-inserted into the uterus for the embryo implantation process
The baby born is known as a test tube baby
