Endometrial polyps are identified by hysteroscopy in 16–26% of women with otherwise unexplained infertility and the rate is much higher (46%) in infertile women with endometriosis (Kim et al., 2003; de Sa Rosa e de Silvaet al., 2005). 


Studies suggest that endometrial polyps <2 cm in size appear to have limited impact on IVF outcome. 

a number of studies demonstrated that local injury to endometrium by endometrial biopsy increases implantation and pregnancy rates in subsequent IVF–embryo transfer cycles (Barash et al., 2003; Raziel et al., 2007; Zhou et al., 2008).

Available methods to improve implantation in gynecological diseases.

Gynecological disease	Therapy methods
Endometriosis	Excision or laser/diathermy ablation of endometriosis implants

Hydrosalpinges	Salpingectomy
	Proximal tubal occlusion (if salpingectomy is technically difficult or not feasible)
Endometrial polyp	Hysterescopic polypectomy
PCOS	Weight loss
	Insulin sensitizers
Adenomyosis	GnRH agonist treatment
	Surgical excision
Endometritis	Antibiotic therapy
Endometrial dysfunction due to ovarian stimulation	Cryopreservation of embryos
