由於hcg可代替黃體分泌激素，以維持子宮內膜的厚度，因此若分泌量不夠就可能會造成流產

無法維持子宮內膜厚度

詳解提供者：Miao Miaw Zhang

沒有足夠HCG會導致無法維持子宮內膜的增厚，使胚胎無法順利著床導致流產

詳解提供者：katte過了一關剩下兩關

會流產
hCG的功能類似黃體酮，會抑制子宮收縮並維持內膜厚度
若濃度不足以維持功能
會導致月經來潮
進而小產

Although proprioceptors are known as non- nociceptive mechanoreceptors, they also express the pro- nociceptive acidsensing ion channel 3 (ASIC3). To probe the role for proprioceptors in sensing acidosis (or sngception), we found that genetic deletion of Asic3 in proprioceptors but not in nociceptors abolished acid- induced chronic hyperalgesia in mice. Chemo- optogenetically activating proprioceptors resulted in hyperal-gesic priming that favored chronic pain induced by acidosis. In humans, intramuscular acidification induced acid perception but not pain. Conversely, in a spinal cord– injured patient who lost pain sensation in the right leg, pro-prioception and sngception were remaining somatosensory functions, associated with the spinal dorsal column. Together, evidence from both mouse and human studies suggests a role for proprioceptors in sngception.摘要引用自：Cheng-Han Lee et al ,A role for proprioceptors in sngception.Sci.Adv.11,eabc5219(2025)
