Abstract Background Infertility is a global problem that refers to the absence of pregnancy after 12 months intercourse without using contraception. Assisted reproductive techniques (ART) are treatment technique for infertile patients. Poor ovarian response stimulation (POR) one challenges in field ART. POR people whom, despite appropriate stimulation, number oocytes retrieved less than expecte...

Controlled ovarian hyperstimulation is one of the major steps of in vitro fertilization. The inaccessibility or non-visualization of developing follicles on transvaginal sonography (the preferred imaging method) may be misjudged as a poor response, resulting in cycle cancellation. It is necessary to scrupulously appraise proxy indicators for ovarian response, such as estradiol levels, endometri...

Endometriomas account for 35% of benign ovarian cyst. Convincing evidence has emerged showing the reduced responsiveness to gonadotropins after ovarian cystectomy. Surgery should be envisaged only in the presence of large cyst or with severe symptoms. For endometriomas less than 3 cm cyst, aggressive removal of same may lead to a poor response during ovulation inductions.

background: smoking has negative effects on reproductive process. exposing to cigarette smoking (passive smoking) may exert some effects as the direct smoking. objective: the aim of this study was to evaluate the correlation between ovarian response and passive smoking in women who underwent art cycles. materials and methods: one hundred-sixty patients who underwent icsi between 2000 and 2001 w...

BACKGROUND In primates, androgens can play a synergistic role with FSH in promoting the early follicular recruitment, which is critical in assisted reproduction technique programmes. OBJECTIVE To assess whether poor responders can benefit from androgen application. METHODS Inclusion criteria were a previous poor ovarian response to controlled ovarian stimulation and a decreased hormonal ova...

OBJECTIVE To investigate whether poor response to controlled ovarian stimulation (COS) is due to a qualitative decline in ovarian function. METHODS This retrospective cohort study included 436 patients younger than 35-years old, undergoing COS for intracytoplasmic sperm injection (ICSI). Patients with four or fewer MII oocytes after COS (poor-responder group, PR, n = 52) were age-matched with...
