Agha-Hosseini M, Aleyaseen A, Safdarian L, Kashani L,
Volume 65, Issue 11 (2-2008)
Abstract

Background: Oocyte donation and assisted reproductive technology (ART) give women with ovarian failure, advanced reproductive age, inheritable disorders or recurrent implantation failure, the ability to conceive. The success of oocyte donation is reportedly influenced by multiple parameters of the oocyte donor and recipient. The objective of this study was to evaluate the donor and recipient variables affecting the outcome of oocyte donation.

Methods: In this retrospective study, we analyzed 51 oocyte donation cycles of 45 women in an in vitro fertilization clinic. Data collected included age, body mass index, endomet-rial thickness, cycling and gravidity of recipients and the age of donors.

Results: The clinical pregnancy rate was 40% per recipient and 35% per cycle resulting in 9 singleton, 7 twin and 2 triplet gestations. Embryo implantation rate was 27%. Oocyte fertilization rates among patients who had become impregnated and those who had not were 75% and 79%, respectively of 18 pregnancies, 15 culminated in a live birth (33% live birth rate). There was no significant relationship between incidence of pregnancy and mean age, BMI, gravidity, cyclicity of recipients and age of donors. There was a significant difference between the endometrial thickness of patients who became pregnant and those who did not (p=0.048). The number of transferred embryos was positively associated with pregnancy (p=0.006).

Conclusion: The factor that most reliably predicts the outcome of oocyte donation cycles is oocyte recipient endometrial thickness. Donor age from 20-34 years dose not affect clinical pregnancy rates. Donors in their early 30's are considered to be the best candidates for oocyte donation.


Evaluating thrombophilia in severe ovarian hyperstimulation syndrome
Safdarian L, Mohammadzade M, Agha Hosseini M, Alleyassin A, Sarvi F,
Volume 70, Issue 1 (4-2012)
Abstract

Background: Ovarian hyper stimulation syndrome (OHSS) and its consequences, especially thromboembolic events, are of the most dangerous complications of assisted reproductive technologies (ART). It is unclear whether a thrombophilic predisposition or changes in blood components during clinical presentation of OHSS increase thrombotic risks. Testing for certain thrombophilias in selected high risk patients may help risk assessment and decision-making about prophylactic measures.

Methods: In this study carried out in April 2010 to March 2011, 108 in vitro fertilization candidates with ≥20 follicles following ovarian stimulation were recruited. Protein S, protein C, antithrombin, lupus anticoagulant and anticardiolipin antibodies were measured. Blood tests were compared between severe and non-severe OHSS groups and their changes were traced after onset of clinical OHSS in 43 patients presenting with severe symptoms by repeating the tests at hospital admission.

Results: Mean protein S activity was lower in severe OHSS group (101.7±16.3 vs. 118.4±17.0 P<0.001). After clinical presentation of severe OHSS, this level decreased to 91.6±20.1 (P<0.001). Antithrombin levels decreased 2.09% after the onset of symptoms in the group with severe OHSS, but this difference was not statistically significant (P=0.051). Protein C, lupus anticoagulant and anticardiolipin antibodies were not correlated to severe OHSS development.

Conclusion: Patients with relatively lower protein S activity were at higher risk for the development of severe OHSS, and its dangerous consequences. During clinical OHSS presentation, protein S decreased even more, and patients were more vulnerable to hypercoagulability states. These points should be kept in mind in risk assessment and adoption of prophylactic strategies.

Abstract
Background: Sexual health is one component of reproductive health that has great impact on the health of individual and society. Sexual health has expressed as a strategy to achieve the millennium development goals. To date, many Iranian studies have addressed the issue of reproductive and sexual health but no study has addressed the definition of sexual health and described its components. Therefore, this study aimed to explore the definition of sexual health and provide a description of its components. Methods: This qualitative study was conducted from June 2009 to November 2013 in Tehran, Iran. Participants were Iranian sexual health experts selected by targeted sampling. Data was collected through semi-structured interviews. All interviews were audio-taped and transcribed verbatim with participants’ permission and then coded by researcher. Development of codes and themes was inductive and arose from the interviews. Data collection was stopped when data saturation was reached. Data was analyzed through conventional content analysis. Results: The theme of individual and family health was extracted from data. From this theme and its categories, the definition of sexual health and its components was extracted including knowledge and information (training needs), physical and mental health, economic needs, social and cultural values and religious values. Based on the results, the sexual health of adults is satisfying from sexual needs by establishing a healthy and socially defined relationship with someone of the opposite sex. Conclusion: According to this study, sexual health has a special definition in each age group and also has different requirements. To start a healthy sexual relationship, at first a correct relationship between a woman and a man must shape. A relationship that is based on customary, religious and social values. Sexual health is a system that consists of abstract components and without proper formation of each of these components we will not be able to access sexual health completely. It seems one of the most important components of sexual health is the knowledge and information about sexual issues. However, further studies are needed to confirm this result.

Abstract
Background: The position of each subject area in scientific production can indicate the ability of the scientific performance of that subject field. Since obstetrics and gynecology is one of the most important clinical sciences discipline of medical science, this study aimed to evaluate the scientific production in the field of obstetrics and gynecology before and after the Iran health reform plan.
Methods: This study is a scientometrics, time interval in the study was from 2008 to 2017 on Iranian articles based on the indexes of the number of documents, the number of citations received, the number of citations to each article, and the H-index of obstetrics and gynecology field based on the Web of Science database. It Indicators investigated, was extracted separately from the analysis section of the database.
Results: The average citation per article, the number of documents and the number of citations in the 5 years before the health reform plan respectively in the field of obstetrics and gynecology equal to 10.44, 196.6, 1750.6 and after the implementation of the health reform plan, equal to 3.89, 282.6, 1031.4. Also, the level of international collaboration before and after the project is 13.06 and 13.25, respectively. Also in the field of gynecology and obstetrics, Ramezani Tehrani, with 1.91% of all articles was the most reproductive writer, and Tehran University of Medical Sciences, with the highest scientific productions in the field of obstetrics and gynecology by 23.77% of all productions. Finally, the field of obstetrics and gynecology had the highest share of scientific production by 66.88%.
Conclusion: The findings showed that the scientific production of obstetrics and gynecology, in terms of quantity (number of documents), after the health reform plan, has been growing, but the quality (citation, H-index) is decreasing. Also, international collaboration has grown after the health reform plan. The findings also showed that before and after the health reform plan, the most cooperation was with the United States and the rate has been lower with Asian countries.

Abstract
Background: Infertility is defined as the failure to achieve pregnancy after one year or more of regular unprotected sexual intercourse. Assisted reproductive technologies (ART) represent a key therapeutic approach for infertile couples. Bisphenol-A (BPA), a compound found in plastic polymer products, has been associated with increased infertility risk. This systematic review addresses whether BPA affects ART outcomes.
Methods: A comprehensive and systematic literature search was conducted across PubMed, Google Scholar, Web of Science, and Scopus up to December 2024 without any language or time restrictions. The search strategy combined relevant keywords and medical subject headings such as “bisphenol A,” “infertility,” “assisted reproductive technology,” “in vitro fertilization,” and “embryo implantation.” All human studies assessing the relationship between BPA exposure and ART outcomes were considered. After removing duplicates and screening titles and abstracts, 23 studies that met the inclusion criteria were reviewed in detail. The selected studies included cross-sectional and prospective cohort designs, and data on sample size, BPA measurement methods, and reproductive endpoints were extracted for qualitative synthesis.
Results: The reviewed studies consistently indicate that exposure to BPA is associated with adverse reproductive outcomes, particularly in women undergoing IVF treatment. Evidence suggests that higher BPA levels correlate with fewer retrieved oocytes, reduced oocyte maturation rates, and impaired ovarian response to hormonal stimulation. Several studies also observed reduced estradiol concentrations and lower fertilization and cleavage rates, leading to decreased implantation success and clinical pregnancy rates. In addition, diminished ovarian reserve markers, such as anti-Müllerian hormone and antral follicle count, have been negatively influenced by BPA exposure. Male factors were also affected, with reports of decreased sperm motility, abnormal morphology, and increased DNA fragmentation, which could compromise embryo quality and early development. Variability in study methodologies, small sample sizes, and differences in BPA detection techniques, however, make direct comparison challenging.
Conclusion: Current evidence supports an inverse association between BPA exposure and fertility outcomes, but further prospective studies with larger sample sizes and more precise measurement methods are needed.
