In Vitro Fertilization01:24

In Vitro Fertilization

326
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Birth Control Methods

325
Vasectomy is a surgical form of male sterilization that involves severing and sealing the vasa deferentia, preventing sperm from mixing with semen during ejaculation. Because a vasectomy does not impact the testes' ability to produce testosterone, hormone levels, libido, and sexual function generally remain unchanged. While vasectomy is highly effective in preventing pregnancy, with a success rate near 99.85%, rare cases of recanalization (spontaneous reconnection) can occur. Although...

Infertility in Males01:23

Infertility in Males

295
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Infertility in Females01:28

Infertility in Females

348
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of...

Fertilization01:38

Fertilization

71.1K
During fertilization, an egg and sperm cell fuse to create a new diploid structure. In humans, the process occurs once the egg has been released from the ovary, and travels into the fallopian tubes. The process requires several key steps: 1) sperm present in the genital tract must locate the egg; 2) once there, sperm need to release enzymes to help them burrow through the protective zona pellucida of the egg; and 3) the membranes of a single sperm cell and egg must fuse, with the sperm...

Spermatogenesis01:41

Spermatogenesis

102.6K
Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male...

  • 临床试验分析临床试验分析
  • 生育能力研究生育能力研究

背景情况:

  • 生育能力受到各种因素的影响,包括生育窗口内的性交时间.
  • 定时性交,包括排卵预测,旨在增加怀孕的可能性.
  • 排卵预测的方法包括激素测量,基于生育意识的方法 (FABM) 和超声波,每个方法都有潜在的缺点,如压力和成本.

研究的目的:

  • 评估排卵预测方法的好处和风险,以确定试图怀孕的夫妇在怀孕时的性交时间.
  • 评估尿排卵测试和FABM对怀孕结果和不良事件的影响.

主要方法:

  • 进行了随机对照试验 (RCT) 的系统审查,搜索主要数据库和试验注册表.
  • 包含的RCT将使用排卵预测的定时性交与其他预测方法或没有预测的性交进行比较.
  • 主要结局是活产和不良事件;次要结局包括临床怀孕,怀孕时间和生活质量.

主要成果:

  • 尿排卵测试可能会增加活产和怀孕率,而没有排卵预测 (中等质量的证据).
  • 证据不足以确定尿排卵测试对压力,临床怀孕,怀孕时间或生活质量的影响.
  • 由于数据有限,FABM对活产,妊娠结果,压力,焦虑,抑郁,勃起功能障碍,怀孕时间和生活质量的影响仍然不确定.

结论:

  • 使用尿排卵测试进行定时性交可能会改善试图怀孕的夫妇的活产和怀孕率.
  • 没有足够的数据来确定尿排卵测试对不良事件,临床怀孕,怀孕时间和生活质量的影响.
  • 需要进一步的研究,以充分了解使用各种排卵预测方法的定时性交的安全性和有效性.
