Secondary oocyte undergoes meiosis-II to form ootid.

Endometrium regenerates within 5 - 6 days of the cycle.

Labia minora fuses anteriorly to form a skin fold called perpuce in front of small erectile organ, the clitoris. Labia minora also fuse posteriorly to form a membranous fold, called fourchette.

It is the placenta with only three barriers.

Mitochondrion is present in the middle piece of sperm as it provides energy (in the form of ATP) to the sperm for entry into the ova and helps in the metabolism of the whole sperm.

Spermatogenesis is the meiotic division through which the sperms are formed. This occurs in scrotal sac. Its main function is to provide the ideal temperature required for sperm formation.

Vagina contains cervix. This part gets dilated at the time of child birth.

50 years to 55 years is the average age of menopause in the females. At this stage, menstrual cycle completely stops.

Oxytocin is responsible for milk ejection after a baby's birth.

During implantation, a zygote is termed as blastocyst. The blastocyst is a structure formed in the early development of mammals. It possesses an inner cell mass (ICM), which subsequently forms the embryo.

Progesterone levels are not at peak during ovulation period.

The oviducts (fallopian tubes), the uterus and the vagina constitute the female accessory ducts. Each fallopian tube is about 10-12 cm long and extends from the periphery of each ovary to the uterus; the part closer to the ovary is the funnel-shaped infundibulum.

The tertiary follicle changes into the mature follicle or Graafian follicle. The secondary oocyte forms a new membrane called zona pellucida surrounding it. The Graafian follicle now ruptures to release the secondary oocyte (ovum) from the ovary by the process called ovulation.

Includes events from the formation of embryo to the time of birth

Includes cycle days 1-5 and bleeding takes place during this phase

The morula, a collection of around 30 cells (blastomere), is created at about 96 hours. Because these cells arise only through the cleavage of the zygote and all are found inside the pellucid zone, which cannot expand, no growth is seen. Every new cell is thus only half as large as the cell from which it derives.

It is homologus to penile urethra.

It is secreted by pituitary gland. It helps in lactation in nursing mothers.

Oocyte is liberated from ovary under the influence of LH completing meiosis I and before the completion of meiosis II.

Tunica vasculosa is the protective covering of testis that consists of network of capillaries surrounded by delicate connective tissue.
