Abstract

:Chronic energy deficiency can impair the hypothalamic-pituitary-gonadal (HPG) axis and lead to hypothalamic anovulation in underweight women. This review presents the syndromes related to underweight status that are associated with infertility, summarizes the underlying mechanisms, and reviews the available treatment options. Eating disorders, such as anorexia nervosa (AN), constitute the most common cause of infertility in underweight women, who, in addition, experience miscarriages, and sexual dysfunction. The relative energy deficiency in sports (RED-S; former terminology: athlete's triad) involves menstrual dysfunction due to low energy availability, which results in anovulation. Moreover, lipodystrophies, malnutrition, starvation, systematic illnesses (malignancies, endocrinopathies, infectious diseases, advanced chronic diseases, neurologic illnesses), and the utilization of drugs can cause excessive weight loss. They may result in fertility problems due to the loss of adipose tissue and the subsequent hormonal disturbances. Each of these conditions requires multidisciplinary management. Nutritional counseling should target the restoration of energy balance by increasing intake and reducing output. Medical treatment, recommended only for patients who did not respond to standard treatment, may include antipsychotics, antidepressants, or leptin administration. Finally, psychiatric treatment is considered an integral part of the standard treatment.

摘要

: 慢性能量缺乏可损害下丘脑-垂体-性腺 (HPG) 轴,并导致体重不足妇女下丘脑无排卵。本综述介绍了与不孕症相关的体重不足状态相关的综合征,总结了潜在的机制,并综述了可用的治疗方案。饮食失调,如神经性厌食症 (AN),是体重过轻妇女不孕的最常见原因,此外,还会出现流产和性功能障碍。运动中的相对能量不足 (RED-S; 前术语: 运动员三联征) 涉及由于低能量可用性导致的月经功能障碍,导致无排卵。此外,脂肪营养不良、饥饿、系统疾病 (恶性肿瘤、内分泌疾病、传染病、晚期慢性疾病、神经系统疾病) 和药物的使用可导致过度的体重减轻。由于脂肪组织的损失和随后的激素紊乱,它们可能导致生育问题。每一种情况都需要多学科管理。营养咨询应该通过增加摄入量和减少产量来恢复能量平衡。仅推荐用于对标准治疗无反应的患者的药物治疗可包括抗精神病药、抗抑郁药或瘦素给药。最后,精神病治疗被认为是标准治疗的一个组成部分。

METHODS::1. Glutathione S-transferases (GST) and cytochrome P450s (CYPs) are xenobiotic metabolizing enzymes participating in the protection of cell. The present study aimed to investigate the relationship between polymorphisms of glutathione S-transferase M1 (GSTM1) null, glutathione S-transferase T1 (GSTT1) null, glutathione S-transferase P1 (GSTP1) Ile105Val, cytochrome P450 1A2 (CYP1A2) 734 C→A, cytochrome P450 2D6 (CYP2D6) 1934 G→A and male infertility.2. A total of 306 azoospermic or oligozoospermic infertile men and 129 normozoospermic or fertile controls were enrolled in the study. Multiplex polymerase chain reaction (PCR) or PCR-restriction fragment length polymorphism methods were used for genotyping. There was a significant relationship between male infertility and CYP2D6 GG genotype (p < 0.001). CYP1A2 AA genotype was slightly higher in the infertile group (p = 0.056).3. There was no association between GSTT1 null polymorphisms and male infertility (p = 0.068), GSTM1 null (p = 0.843) and GSTP1 Ile105Val (p = 0.192) genes. GSTM1 null genotype frequency was higher in azoospermic men (p = 0.009). Men carrying CYP1A2 AA genotype had higher risk of infertility risk (OR = 3.14; %95 CI = 1.16-8.54) in the smoker group.4. Our results demonstrated that polymorphisms of CYP2D6 and CYP1A2 may play a role in idiopathic male infertility in our sample population.

METHODS:PURPOSE:This study evaluated the effect of counseling based on the choice theory on irrational parenthood cognition (IPC)- and marital quality in infertile women. DESIGN AND METHODS:This randomized controlled trial was conducted on 50 primary infertile women in Zanjan, Iran. Stratified block randomization was used to allocate participants to groups. The intervention group received counseling, but the control group received routine care. Data were collected using the IPC and marital relationships quality based on the Glasser's choice theory. FINDINGS:A statistically significant difference was found between the groups in IPC (P = 0.005), but the difference in marital quality was not statically significant ( P = 0.085). PRACTICE IMPLICATIONS:Counseling can be used for decreasing IPC, but more interventions are needed to increase marital quality.

METHODS::A decrease in cancer deaths has resulted in the possibility of child bearing for many young adult cancer survivors. Most antitumor treatment modalities are detrimental to female fertility, and methods for fertility preservation before gonadotoxic treatment, including cryopreservation of oocytes, embryos and ovarian tissue, have therefore been developed. This review focuses on the ovarian function of cancer patients, the safety and efficacy of fertility preservation methods, and the pregnancy outcomes of these patients. Breast cancer and hematological tumors constitute the majority of cancers in reproductive-aged female oncology patients. Ovarian function may not be impacted by breast cancer cells, while in patients with hematological malignancies, decreases in anti-Müllerian hormone and antral follicle counts have been demonstrated. In most cases, patients can undergo ovarian stimulation without delaying treatment, and a new stimulation protocol known as dual stimulation, which may be more efficient, has now been developed. Birth outcomes are also acceptable in cancer patients.
