Infertility is defined as the inability to conceive even after engaging in regular unprotected sex or the biological inability in contributing to conception. It can also be defined as a female’s inability in carrying the pregnancy to full term. The failure of a couple to conceive after regular sexual intercourse for twelve months without the use of contraceptives is referred to as infertility in most countries.

From studies conducted by Mayo Clinic in the US, about 40-50 %of infertility cases are caused bu problems in the woman while 20% of the cases are due to man’s problem. The study also veiled that 30-40% of infertility cases are due to problems associated with both the woman and the man. It is estimated that about 10% to 15% of all the couples in the United States are infertile according to the Health and Human Services Department.

Through egg freezing
IVM – In Vitro Maturation is a process where immature eggs undergo maturation in a laboratory.
Ovulation induction- this involves artificial stimulation of the follicles leading to simultaneous egg production in a single cycle.
