The More the Merrier? The Effect of Fertility Preference on Marriage Outcomes

2019

This paper analyzes how fertility preference affects individuals' marriage outcomes. By using the selective Two-child Policy in China, which relaxed Han Chinese and only child's birth quota hence made them more attractive, I find that after the policy, the treatment group is more likely to marry same-type spouses to have more children. Moreover, to meet their fertility preference, Han Chinese and only child men searched longer and bought more expensive houses before marriage, and transferred more to their wives in terms of income and education.

Impact of FIGO type 3 uterine fibroids on in vitro fertilization outcomes: A systematic review and meta‐analysis

2023

Background: The effect of FIGO (the International Federation of Gynecology & Obstetrics) type 3 myomas on in vitro fertilization (IVF) is uncertain. Objectives: To evaluate whether FIGO type 3 myomas affect IVF outcomes, through a systematic review and meta-analysis (CRD42022379700). Search strategy: Electronic databases were searched until November 15, 2022. Selection criteria: Studies evaluating the effects of FIGO type 3 myomas on IVF outcome. Data collection and analysis: Pooled results were expressed as odds ratios (OR) with 95% confidence intervals (CI). Heterogeneity was assessed using Higgins I2 . Sources of heterogeneity were explored with sensitivity and subgroup analyses. Mai…

Persistent Employment Instability and Fertility Intentions

2014

Our paper adds to the growing literature on the measurement of employment instability and its consequences on fertility dynamics. Many of these studies disregard that the persistence (duration) in an unstable condition, more than the status itself, may have the most severe consequences on subsequent family choices. In this paper, we propose an index of persistence in employment instability (EINI) that synthesizes all the information inside the individual sequence of employment statuses in a single number accounting simultaneously for the duration, sequencing, intensity, and labour market circumstances. Then, we test its impact on short-term childbearing intentions of Italian couples separat…

Laparoscopic lymph node dissection should be performed before fertility preserving treatment of patients with cervical cancer

2012

Objective: The aim of this study is to assess our results of treatment of women with stage I cervical cancer > 2 cm in diameter seeking fertility preservation. Treatment consisted of Laparoscopic Pelvic and Paraaortic Lymphadenectomy (LPPLND), and when no nodal metastasis was detected, neoadjuvant chemotherapy (NACT) followed by radical vaginal trachelectomy (RVT). Patients with positive lymph nodes underwent primary chemoradiation. Methods: A cohort of women younger than 40 years of age with stage I disease > 2 cm who underwent LPPLND and either NACT and RVT or chemoradiation. Oncological outcome was evaluated prospectively. Results: Eighteen women were eligible for this study. Twelve (67%…

Clinical Recommendation Radical Trachelectomy for Fertility Preservation in Patients With Early-Stage Cervical Cancer

2012

Radical trachelectomy (RT) is a fertility-sparing procedure with the aim to provide adequate oncological safety to patients with cervical cancer while preserving their fertility. In the current review, indications, development of the procedure, technical aspects, preoperative and postoperative management, and oncological, fertility, and obstetric outcomes are discussed and studied with respect to whether the procedure is performed abdominally or vaginally. Complications of RT, staging, and more conservative alternatives to RT are discussed as well. A systematic MEDLINE search was performed, which yielded 218 articles, of which 75 were selected for further analysis based on the number of pat…

Uterus transplantation: animal research and human possibilities

2012

Uterus transplantation research has been conducted toward its introduction in the human as a treatment of absolute uterine-factor infertility, which is considered to be the last frontier to conquer for infertility research. In this review we describe the patient populations that may benefit from uterus transplantation. The animal research on uterus transplantation conducted during the past two decades is summarized, and we describe our views regarding a future research-based human attempt.

Physiology and Pathology of Ovarian Hyperstimulation Syndrome

2010

Ovarian hyperstimulation syndrome (OHSS) occurs when ovaries primed with follicle-stimulating hormone/leuteinizing hormone (LH) are subsequently exposed to human chorionic gonadotropin (hCG). The ultimate pathophysiological step underlying this clinical picture is increased vascular permeability (VP). With the administration of hCG, the expression vascular endothelial growth factor (VEGF) and VEGF receptor 2 (VEGFR-2) mRNA increases significantly rising to a maximum coinciding with peaked VP. Immunohistochemistry shows the presence of VEGF and VEGFR-2 proteins in the granulosa-lutein and endothelial cells of the entire corpus luteum. These findings suggest that the syndrome can be prevented…

Comparison of a Manual and an Automated Method to Estimate the Number of Uterine Eggs in Anisakid Nematodes: To Coulter or Not to Coulter. Is That th…

2007

Studies reporting numbers of eggs in vagina and utero in nematodes often give little information of the technique used for the estimations. This situation hampers comparison among studies, because, so far, differences in estimations provided by different techniques have not been assessed. This note examines whether a manual method based on visual counts in aliquots and an automated method using a Coulter counter yield equivalent estimations of egg numbers in vagina and utero of 3 anisakid nematode species (Anisakis simplex, Pseudoterranova decipiens, and Contracaecum osculatum). The number of eggs from 50 females per nematode species was estimated using both techniques. The automated and ma…

Do vitamin E supplements in diets for laboratory animals jeopardize findings in animal models of disease?

1999

Abstract Vitamin E has been supplemented to the diets of farm animals to improve fertility, health, growth rates and quality of animal products. Because of the positive experience obtained in farm animals, vitamin E has been added in increasing amounts to the diets of laboratory animals. Today, vitamin E levels in standard rodent maintenance diets range from 30 mg/kg (France, United States), 90–120 mg/kg (Netherlands, United Kingdom) to as much as 200 mg/kg (Germany). While increasing fertility and health of laboratory animals, these vitamin E supplements affect diverse pathophysiological conditions and thus the outcome of animal models of disease. Because of the large variability of vitami…
