Answer 1

Ans 2

Fimbriae – (c) sweeps ova into oviduct

Infundibulum- (e) terminal/ uterine end of oviduct

Isthmus –(a) muscular tube that helps maintain the fetus within the uterus

Uterus – (f) location of egg implantation and fetal development

Cervix- (d) ovarian end of the oviduct, mucosa contains a deep folds

"Vagina "–(b)allows copulation and the shedding of endometrium

Ans 1

1. Lack of testosterone receptors on all cells of the body of fetus with XY chromosomes results- into the androgen insensitivity syndrome in which person is genetically male but their behaviour or physical appearance resembles like a female . as the testosterone is the most imp. Hormone for the male traits which causes the reproductive growth and many more functions .
2. Autoimmune recognition of ova surface proteins results into the production of self -antibodies which destroys the ova proteins ., whenever the cells sees these cells they are destroyed by immune system.
3. Interruption of sympathetic innervations in the" penis "  cause the changes in sexual activity and also the male reproductive physiology . it will affect the arousal, ejaculation etc . function as most signals are going through the sympathetic innervations . Sympathetic innervation originates in the lower thoracic and lumbar cord , the psychogenic erection mediated via the sympathetic fibers in conjunction with the parasympathetic. Ejaculatory disorders (primarily anejaculation) are highly prevalent in such cases . not in "penis" the disturbance also affects the female part too
4. Lack of estrogen receptors in the endometrium

Primarily the estrogens help to stimulate the growth of the egg follicle if the receptors are absent in the endometrium the stimulation of the eggs are affected . besides as in male the testosterone function as the imp. for the male characteristics so the same here for female .

It maintains the thickness of the' vagina' ,

In uterus Estrogen enhances and maintains the mucous membrane that lines the uterus. It also regulates the flow and thickness of uterine mucus secretions
