Patients of genital TB infertile: 40-80%(mc presenting complaint of genital tb -INFERTILITY >pain)

Incidence of genital tb in patients with infertility-17%

Mullerian anomaly association with urinary tract abnormality-30%

Risk of endometriosis is 7 times more if 1st degree relative is affeced with endometriosis

Patient with history of ovarian ca in 1st degree relatives,so risk of ovarian cancer-7%(dnb 2014)

Recurrence rate ater incision and drainage of endometrial cyst-50%(€€therefore best t/t - cystectomy)

Rate for conversion to frank cancer
cin-1 : 1%
Cin-2 :5%
Cin-3 : >12%(22)
Cin 1 conver to CIS -11%
Cin 1 time to regress to normal-2yrs

Protection rate of hpv vaccine-70%

Risk of involvement of ovaries in ca cx-11%

BSO can reduce the risk of breast ca by 50%

Dermoid always benign but risk of cancer -less than 2%

Risk for lifetime
brca 1-ovarian ca-35-45%
Hnpcc-endometrial ca-75%

Post mentrual bleeding patients developing endometrial ca-10%
any abnormal uterine bleeding above 40yrs endometrial ca should be ruled out therefore endometrial biopsy to be done rather than PAP

Endometrial hyperplasia(pre invasive)
simple withOUT atypia-1% risk for endometrial ca
Complex WITHOUT atypia-3%
Simple with atypia-8%
Complex with atypia-20%
(Without atypia progestrogens to be given for MINIMUM 14 days)

Use of OCP for 5yrs decrease the risk ovavarian ca by 50%

Molar preg
partial-90% triploidy 10% tetra

Complete 80-90% monospermic 46xx,10% 46xy
