# Introduction

nfertility is a condition of the reproductive system that prevent the conception of children. It affects approximately 10-15% of couples throughout the United States. The diagnosis of infertility is usually given to couples who have been attempting to conceive for at least 1 year without success. (1) Global infertility prevalence rates are difficult to determine, due to the presence of both male and female factors which complicate any estimate which may only address the woman and an outcome of a pregnancy diagnosis or live birth. One in every four couples in developing countries had been found to be affected by infertility. (2) When the cause of infertility exists within the female partner, it is referred to as female infertility. Female infertility factors contribute to approximately 50% of all infertility cases, and female infertility alone accounts for approximately one-third of all infertility cases. The most common causes of female infertility Author ? ? ?: Banoon Center for Assisted Reproduction & Obstetrics & Gynecology. Banoon IVF Center. e-mail: musab.noor13@gmail.com include problems with ovulation, damage to fallopian tubes or uterus, or problems with the cervix. Age can contribute to infertility because as a woman ages, her fertility naturally tends to decrease. (3) The risk of infertility from cancer treatment depends on many things, like your cancer type, age and pre-treatment fertility status. Treatment specifics such as duration and dose of chemotherapy or radiation and location and scope of surgery or radiation also impact fertility. Specifically, treatment can cause the following:

? The ovaries no longer contain a supply of health eggs ? Damage to the reproductive system prevents a fertilized egg from successfully implanting and growing in the uterus ? Damage to the reproductive system prevents you from being able to carry a pregnancy. (4) Chemotherapy can stop your ovaries from working. This causes infertility, which can be temporary or permanent. It can also bring on the menopause.


# a) Temporary Infertility

With temporary infertility, your periods may become irregular or stop during treatment. But they'll go back to normal once your treatment is over.

This happens in about a third of all women whose periods stop because of chemotherapy. It takes about 6 to 12 months for your periods to go back to normal.


# b) Permanent Infertility

Permanent infertility is more likely if you have higher doses of the drugs. It's also more likely in older women than young women -especially if you're getting close to the age where you'd naturally have the menopause.

Some chemotherapy drugs can be very damaging to the eggs in your ovaries, so that none are left after treatment. If this happens, you can no longer get pregnant and you might have symptoms of the menopause. (5) It is also known that there is a higher rate of obstetric complications in patients who have received radiation treatment in comparison with the general population; complications include spontaneous abortions, preterm labor and low-birth weight infants. (6) II. Literature Review Study done by Kutluk Oktay et al showed that; BRCA1 mutations are associated with occult primary ovarian insufficiency. This finding may, at least in part, explain the link between infertility and breast/ovarian cancer risks. (7) 


# III. Justification

There is no published data concerning the association between cancer and infertility.


# IV. Objectives

To know the prevalence of cancer among selected group of Sudanese ladies with fertility disorders.

V. 


# Material and Method


# Ethical Consideration

All participants were informed about the purpose of the study and all of them were consent.


# VII.


# Result

The prevalence of cancer among the selected group was 10% (6% was breast cancer, 4% other types of cancer).


# VIII.


# Discussion

The prevalence of cancer among the study group was high and that may give us a link between cancer and infertility with strength of this link was increased among the participants with breast cancer , then our study agree with the previous study done by Kutluk Oktay et al that showed association between breast cancer and infertility.


# IX.


# Conclusion

Further studies should be done involving large sample size from different races.
