|A cap-like structure over the nucleus of a sperm cell, containing enzymes crucial for fertilization as it helps the sperm penetrate the egg.
|A stage in early human embryonic development that consists of a fluid-filled cavity and precedes implantation into the uterine wall.
|A wide fold of peritoneum connecting the sides of the uterus to the walls and floor of the pelvis, providing support to the uterus.
|The lower, narrow part of the uterus that opens into the vagina, with a canal that allows passage between the uterus and vagina.
|A series of rapid cell divisions following fertilization, resulting in the embryo's progression from a zygote to a multicellular structure without growth in size.
|A temporary endocrine structure in the ovary that secretes hormones, primarily progesterone, to prepare the endometrium for a potential pregnancy.
|The lining of the uterus, which thickens during the menstrual cycle in preparation for possible implantation of an embryo.
|Tubes extending from the uterus to the ovaries, facilitating the passage of eggs from the ovaries to the uterus.
|The process by which a sperm cell and an ovum (egg) merge to form a zygote, initiating embryonic development.
|A benign, solid, noncancerous tumor in the breast.
|A fluid-filled sac in the ovary that contains an immature egg (oocyte); it grows and matures in response to hormonal signals during the menstrual cycle.
|The rounded upper part of the uterus.
|Gonadotropin-releasing hormone; released by the hypothalamus to stimulate the pituitary gland to secrete gonadotropins, which influence the menstrual cycle and ovulation.
|Luteinizing hormone; released by the pituitary gland in response to GnRH, with a surge leading to ovulation.
|An early stage in the embryo development consisting of approximately 16 cells, resembling a mulberry, following the cleavage stage and preceding the blastocyst stage.
|The thick, muscular layer of the uterus responsible for contractions during childbirth and menstruation.
|Fluid-filled sacs on the ovary, often forming during the process of ovulation and varying in type, from functional cysts related to the menstrual cycle to pathological cysts.
|A reproductive organ in females that produces eggs (ova) and hormones, such as estrogen and progesterone.
|The release of an egg from the ovary into the fallopian tube, where it can be fertilized by sperm.
|Polycystic Ovarian Syndrome (PCOS)
|A condition characterized by the presence of multiple cysts on the ovaries, leading to hormonal imbalances, irregular menstrual cycles, and fertility issues.
|The process of sperm development, from spermatids to fully mature sperm cells.
|A duct that carries urine from the kidneys to the urinary bladder.
|A muscular organ in the female reproductive system where fetal development occurs; consists of the fundus, body, and cervix.
|The first cell of a new individual formed immediately after the sperm and egg nuclei merge during fertilization.
