Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of assisted reproduction technology. The syndrome is characterized by cystic enlargement of the ovaries and a fluid shift from the intravascular to the third space due to increased capillary permeability and ovarian neoangiogenesis. Its occurrence is dependent on the administration of human chorionic gonadotrophin (hCG). β-hCG and its analogs, estrogen, estradiol, prolactin, histamine and prostaglandins have all been implicated in OHSS but now it is increasingly better understood that the vasoactivesubstances such as interleukins, tumor necrosis factor-α, endothelin-1, and vascular endothelial growth factor (VEGF) secreted by the ovaries have been implicated in increasing vascular permeability. Enlargement of the ovaries causes abdominal pain, nausea and vomiting. Leakage of fluid from follicles, increased capillary permeability leading to third spacing (due to the release of vasoactive substances), or frank rupture of follicles can all cause ascites. Due to leakage of fluid through the impaired blood vessels both within and outside the ovary there is massive fluid-shift from the intra-vescular bed to the third compartment results in intravascular hypovolemia with concomitant development of edema, ascites, hydrothorax and/or hydropericardium. Low-dose gonadotrophin protocols have been implemented to reduce the risks of fertility treatment in polycystic ovary syndrome patients. Prophylactic albumin administration may interrupt the development of OHSS by increasing the plasma oncotic pressure and binding mediators of ovarian origin. OHSS is significantly lower in an antagonist protocol than in an agonist protocol. Cabergoline inhibits partially the VEGF receptor 2 phosphorylation levels and associated vascular permeability without affecting luteal angiogenesis reduces the ‘early’ (within the first 9 days after hCG) onset of OHSS. To prevent thrombosis, subcutaneous heparin 5000-7500 U/d is begun on the first day of admission. These patients need a hospital ward where the clinical picture is well understood and the personnel have expertise in its treatment and follow-up. Admission to an intensive care unit is necessary when critical OHSS develops.

The endocrinology of human pregnancy involves endocrine and metabolic changes that result from physiological alterations at the boundary between mother and fetus. Progesterone and oestrogen have a great role along with other hormones. The controversies of use of progestogen and others are discussed in this chapter. Progesterone has been shown to stimulate the secretion of Th2 and reduces the secretion of Th1 cytokines which maintains pregnancy. Supportive care in early pregnancy is associated with a significant beneficial effect on pregnancy outcome. Prophylactic hormonal supplementation can be recommended for all assisted reproduction techniques cycles. Preterm labor can be prevented by the use of progestogen. The route of administration plays an important role in the drug's safety and efficacy profile in different trimesters of pregnancy. Thyroid disorders have a great impact on pregnancy outcome and needs to be monitored and treated accordingly. Method of locating review: Pubmed, scopus

Reviewing the literature revealed that most of the cases involved the anterior part of the oral cavity of male patients living in developing or underdeveloped countries and also that predisposing factors invariably accompanied infestation.

Introduction:Involuntary childlessness is a distressing condition that has considerable social implications in developing nations.Aim:The present study aims to investigate the less known sociocultural determinants of infertility stress in patients undergoing assisted conception and reproductive treatments.Methods:This cross-sectional research was conducted on 300 men and women with primary infertility. The profile of sociodemographic variables, clinical variables, and sociocultural variables was collected using a locally devised questionnaire. Infertility stress was assessed using the psychological evaluation test.Statistical Analysis:Research data were analyzed using SPSS 15. Chi-square test is used for univariate analysis. Multiple logistic regression with enter method is used to examine the association between infertility stress and sociocultural variables.Results:The findings suggest that in both men and women, low spousal support, financial constraints, and social coercion in early years of marriage predicts infertility distress. Peer-support neither predicts nor protects against distress.Discussion:Family acceptance and social security for infertility is low. Stigma, concealment, and discrimination among men are reported to be high. Distress is three times greater in women with overinvolved family members who had unrealistic expectations from treatments. Taking continuous cycles of fertility treatments seems unaffordable for most patients. Subfertile individuals were socially perceived to be deprived, blemished, incomplete, and sexually incompetent.Conclusion:Data from this investigation, provides a glimpse into sociocultural aspects of infertility. The findings may be useful for identifying targets for individual and family-focused psychological interventions for distress reduction in infertility.
