It is rather difficult to absolutely recover from serious abnormalities whereas some abnormalities are inherited and/or incurable. The guideline of the paper is to describe reproductive abnormalities of males and females and to evaluate IVF success.
It is known that general reproductive abnormalities fall the following categories such as gonadal, chromosomal, hermaphroditism, external genitalia, tract abnormalities, gonadal dysfunction, gonadal descent. It is mentioned that some reproductive abnormalities are connected with gonad development that can affect the later sexual development either of man or woman. Gonad development can lead to infertility. Other reproductive abnormalities are connected with external genitalia and the tract which can also be caused by gonadal abnormality. (Carlsen 1992)
Abnormalities do make the treatment process more complication and log-lasting, because it is necessary to cure abnormality firstly and only then start curing infertility. Abnormalities do slow the process of recovery. The success of treatment depends absolutely on the professionalism of doctors and the patient as well.
It is necessary to point out that infertility is inability to have children for men and to become pregnant for women or to carry pregnancy. Normal healthy couples are said to have about 25% chance to have a child each month. It is reported that 95% of normal couples achieve pregnancy within a year. It is more difficult for women from 30-35 to become pregnant and the possibility considerable decreases from 35 years.
It is known that about 15% of married couples are infertile and can't have children. About 60% of infertility causes are connected with inadequate ovulation, cervical factors and/or blocked fallopian tubes. About 42% of infertility is connected with male problems such as bad sperm functioning, abnormal structure of sperm and inadequate sperm counts. But there are more serious reproductive abnormalities which can lead to infertility and than to long period of treatment. (Holbrook 1990)
Unfortunately the IVF success is not very high, because many of reproductive problems significantly decrease the chances to have the child. It is rather difficult to absolutely recover from serious abnormalities whereas some abnormalities are inherited and/or incurable. (Carlsen 1992) Female infertility is told to account one-third of infertility cases. The infertility rate is about 15% whereas some cases are unexplained infertility.
A couple is considered to be infertile if:
1. If they haven't conceived a child after a year of unprotected sexual relations or after half a year in case if woman is over 35. The rapid decline of fertility for women is after 35.
2. If woman is incapable to carry a child to the set term.
Male infertility: reproductive abnormalities
The risk of men's infertility can be increased by such factors as drug use, alcoholic drinks, tobacco smoking, health problems, medicines, age, radiation treatment, environmental toxins (lead and pesticides). (Goldstein 1999)
Male reproductive abnormalities may lead to lower chances to have a child. It means that for example dysfunctional activity of sperm can result in diminished ability to impregnate the ovum. It is necessary to mention that chromosomal abnormalities play significant
