problems with the uterine lining that can affect a woman’s ability to get pregnant and have a successful pregnancy.
A luteal phase defect can refer to one of two problems with the luteal phase - the second part of the menstrual cycle, after ovulation has occurred. First, the phase itself may be too short (only ten days rather than the average 12 to 16), which does not give an embryo enough time to implant successfully. Second, progesterone production in this part of the cycle may be too low, meaning that the lining of the womb will not get thick enough for an embryo to implant before menstruation begins.
When the luteal phase (the time between ovulation and menstruation) is too short (less than 10 days) it may indicate that the corpus luteum is not functioning properly and may prevent implantation of a fertilized egg or may lead to early pregnancy loss.
An abnormality that interrupts the normal luteal phase following ovulation.-M, N
A condition present when the lining of the uterus does not mature properly in response to progesterone secretion by the ovary after ovulation.
Inadequate function of the corpus luteum that may prevent an embryo from implanting in the uterus or may lead to early pregnancy loss.
A condition that occurs when the uterine lining doesnot develop adequately due to inadequate progesterone stimulation or becauseof the inability of the uterine lining to respond to progesterone stimulation.LPD may prevent embryonic implantation or cause an early abortion.
A shortened luteal phase or one with inadequate progesterone production.
characterized by endometrial histology (on endometrial biopsy) that is repeatedly out of phase by more than two days, associated with recurrent pregnancy loss
(LPD) A luteal phase that is shorter than optimal for a fertilized egg to undergo implantation. Very likely if the luteal phase is shorter than normal (11 to 16 days), but not all luteal phases within this range are innocent. Often caused by a prior defect of the follicular phase or of the development of the ovulating tertiary follicle (the preovulatory follicle) and hence there can be a defect of the egg itself (if ovulation has actually occurred) or there can be a luteinized unruptured follicle -- any of which will either increase the risk of miscarriage or will prevent pregnancy altogether for that cycle. Synonymous with luteal phase insufficiency.
A shorter than normal luteal phase described as suboptimal production of progesterone or a lag in endometrial development.
A condition that occurs when the uterine lining does not develop adequately because of inadequate progesterone stimulation; or because of the inability of the uterine lining to respond to progesterone stimulation. LPD may prevent embryonic implantation or cause an early abortion.
an abnormality that interrupts the normal luteal phase following ovulation. During the normal luteal phase, progesterone is produced in increasing amounts following ovulation, which helps prepare the endometrium for implantation of the fertilized egg.
low levels of progesterone in repeated menstrual cycles. Progesterone is a hormone that is essential for the survival of a fetus early in pregnancy. In the past, doctors thought LPD affected miscarriage in early pregnancy but recent studies have not shown this to be true.
(LFD) A cause of Female factor infertility, whereby, due to insufficient progesterone being produced, the fertilised ovum fails to implant into the uterus, or spontaneous miscarriages occur very early in the cycle. ( more...)
A hormone imbalance present during the time after ovulation that may contribute to suboptimal implantation and pregnancy loss.
