The purpose of this document is to review the current methods of diagnosis and evaluation for men with azoospermia.

The purpose of this systematic review is to evaluate if uterine myomas impact the likelihood of pregnancy and pregnancy loss, and if myomectomy influences pregnancy outcomes in asymptomatic women. There is insufficient evidence to conclude that the presence of myomas reduces the likelihood of achieving pregnancy. However, there is fair evidence that myomectomy (open or laparoscopic) for cavity-distorting myomas (intramural or intramural with a submucosal component) improves pregnancy rates and reduces the risk of early pregnancy loss. There is fair evidence that hysteroscopic myomectomy for cavity-distorting myomas improves clinical pregnancy rates but insufficient evidence regarding the impact of this procedure on the likelihood of live birth or early pregnancy loss. In women with asymptomatic cavity-distorting myomas, myomectomy may be considered to optimize pregnancy outcomes.

Standardization improves performance and safety. A template for standardizing the embryo transfer procedure is presented here with 12 basic steps supported by published scientific literature and a survey of common practice of SART programs; it can be used by ART practices to model their own standard protocol.

Although there is currently no definitive evidence linking West Nile virus (WNV) transmission with reproductive cells, it is recommended that practitioners defer gamete donors who have confirmed or suspected WNV infections. This document replaces the previously published document of the same name, last published in 2016 (Fertil Steril 2016;105:e9-10).

This Committee Opinion provides practitioners with suggestions for optimizing the likelihood of achieving pregnancy in couples/individuals attempting conception who have no evidence of infertility. This document replaces the document of the same name previously published in 2013, Fertil Steril 2013;100(3):631-7.

Based on American Society for Reproductive Medicine (ASRM) and Society for Assisted Reproductive Technology data available through 2014, ASRM's guidelines for the limits on the number of embryos to be transferred in in vitro fertilization (IVF) cycles have been further refined in continuing efforts to promote singleton gestation and reduce the number of multiple pregnancies. This version replaces the document titled Criteria for number of embryos to transfer: a committee opinion that was published most recently in August of 2013 (Fertil Steril 2013;99:44–6).

Following the birth of the first child from a transplanted uterus in Gothenburg, Sweden, in 2014, other centers worldwide have produced scientific reports of successful uterus transplantation, as well as more recent media reports of successful births. The American Society for Reproductive Medicine recognizes uterus transplantation as the first successful medical treatment of absolute uterus factor infertility, while cautioning health professionals, patient advocacy groups, and the public about its highly experimental nature.

Luteal phase deficiency (LPD) has been described in healthy normally menstruating women and in association with other medical conditions. Although progesterone is important for the process of implantation and early embryonic development, LPD, as an independent entity causing infertility, has not been proven. This document replaces the document by the same name, last published in 2012 (Fertil Steril 2012;98:1112-7).

The purpose of this ASRM Practice Committee report is to provide clinicians with principles and strategies for the evaluation of couples with male infertility problems. This revised document replaces the document of the same name, last published in 2012 (Fertil Steril 2012;98:294-301).

This document provides the latest recommendations for evaluation of gestational carriers and intended parents. It incorporates recent information from the US Centers for Disease Control and Prevention, the US Food and Drug Administration, and the American Association of Tissue Banks, with which all programs offering gestational carrier services must be thoroughly familiar. This document replaces the previous document of the same name, last published in 2015 (Fertil Steril® 2015; 103:e1–8).

The purpose of this guideline is to review the literature regarding septate uterus and determine optimal indications and methods of treatment for it. Septate uterus has been associated with an increase in the risk of miscarriage, premature delivery, and malpresentation; however, there is insufficient evidence that a uterine septum is associated with infertility. Several studies indicate that treating a uterine septum is associated with an improvement in live-birth rates in women with a history of prior pregnancy loss, recurrent pregnancy loss, or infertility. In a patient without infertility or prior pregnancy loss, it may be reasonable to consider septum incision following counseling regarding potential risks and benefits of the procedure. Many techniques are available to surgically treat a uterine septum, but there is insufficient evidence to recommend one specific method over another.

Although there is currently no definitive evidence linking West Nile virus (WNV) transmission with reproductive cells, it is recommended that practitioners defer gamete donors who have confirmed or suspected WNV infections. This document replaces the previously published document of the same name, last published in 2012 (Fertil Steril 2012;98:e15-6).

All in vitro fertilization programs and clinics should have a plan to protect fresh and cryopreserved human tissue (embryos, oocytes, sperm) and to provide for continuation of patient care in the event of an emergency or natural disaster. This document was reviewed and affirmed by the Practice Committee in 2015.
