| IVF-ET (IN VITRO FERTILIZATION AND EMBRYO TRANSFER) |
IVF-ET was initially considered a treatment of choice for tubal factor infertility. Thus cases of tubal disease, occlusion, adhesions or surgery were considered as other treatments could not offer comparable success. Subsequently 1VF indications expanded to include PCOS wherein better follicular growth and fertilization rates were obtained. Today the indications cover unexplained infertility, advancing maternal age, repeated trials of conservative treatments, ovarian failure, and antispcrm antibodies. IVF offers a possibility of diagnosis of gamete dysfunction. With the advent of ICSI, indications have expanded to encompass almost all cases of male infertility. |

- Women in the perimenopausal age group who do not show proper recruitment of follicles and who have other existing causes of infertility
- Women with genetic disorders
- Those who have undergone radiation therapy
- Those with ovaries that are not accessible by ultrasound due to severe adhesions.
